How to Paint Over Powder Coat

For durable and lasting protection of metal surfaces, powder coating is an excellent choice. The convenient alternative to traditional paint looks good and protects against the elements, along with wear and tear. 

Even though powder coating provides a beautiful, stylish surface, it does wear down over time. That might leave you wondering how to paint over powder coat and whether you should.

It’s possible to paint over a powder-coated surface, but there are some key details to keep in mind before you try. The good news is that this article will tell you what you need to know. Contact us for all your metal fabrication needs, including powder coat finishing.

What Is Powder Coat?

First, you need to understand what powder coat is and how it’s different from liquid paint. To start, you need to know what you’re working with to get a good result.

While powder coating provides a finish resembling a fine paint job, it’s not the same

The coating uses a fine powder made up of pigment and other compounds to adhere the pigment to the metal. The glossy finish is resistant to chemicals, wear, and chipping, which is ideal for durability.

It also means that a powder-coated surface is tricky to paint over.

Challenges to Painting Over Powder Coat

The strengths of powder coating are what make it a challenge to cover with liquid paint and other traditional pigments. The combination of process and the components in the powder coat creates a very slick surface.

Of course, if almost nothing will stick to it, most paint will not adhere to the surface easily either.

Another issue to keep in mind is the condition of the metal underneath the powder coating. Powder coating helps prevent environmental stresses, but it doesn’t eliminate them. 

Over time, different areas of the powder-coating may wear away, but the process can be uneven. As a result, oxidation can attack the metal underneath, creating a surface that won’t cooperate with paint.

How to Paint Over Powder Coat Properly

The best option is to take your powder-coated metal to a qualified professional, who will approach the issue with a few key guidelines. If the coating is completely intact, the technician will lightly sand it. This creates a rougher surface to which the paint can adhere.

If the powder coating has worn away in some places but not in others, the technician may go ahead and sand off the coating entirely. This ensures a consistent surface for the paint application.

If areas of the underlying metal are oxidized, the technician makes sure to get rid of all rust before moving forward. Rust will continue eating away at the metal underneath the paint, increasing the risk of flaking and chipping.

5 Common Challenges of Precision CNC Machining 

The most common issues with machined parts arise with improper maintenance and usage. Below are 5 of the most common errors you may encounter when using CNC machinery. 

1. Applying Wrong Settings and Tools 

Using an inappropriate cutting tool or setting will present challenges and errors. If the cutting tool is not sharp and there is not an appropriate cutting coolant used, a poor surface finish will result. Additionally, this causes a cutter mark on your material and unnecessary wear on your tool. 

Damages occur when the machine settings are wrong. When the feed rate is too high, rough edges and marks appear on your piece. Setting the feed rate too low will burn your workpiece. Wrong settings may even burn your tools. 

2. Machine Vibrating and Chattering 

CNC Machine vibration and chatter are related to tools and settings. If your CNC machine is vibrating or chattering, something needs changing. When the issue goes unfixed, tools will lose durability, the accuracy of dimensions will be affected, and the quality of the workpiece will diminish.

3. Choosing Inappropriate Raw Material 

The material chosen for your project is an important factor. Some machinists will have an easier time working with certain metals. Moreover, some materials require certain strengths when used for specific functions. 

Each metal responds differently to CNC machining. Some metals need extra steps to produce high-quality products, such as deburring. Note how CNC machining affects different metals and parts. 

If you do not take time to consider what metals are best for your project, you may face avoidable issues had you used a different type of material. 

4. Processing and Programming Data 

CNC machining relies on software. This software can easily affect a machine’s performance. Sometimes, issues may arise when the computer software is not productively communicating with the device. For example, the software may dictate machine instructions too slowly. 

CNC machines are programmed and have a programming language. Lack of knowledge of coding and programming data will lead to errors in production and problems with the machines. 

5. Purchasing and Repairing CNC Machines 

CNC machines are expensive and require a hefty investment. CNC machine repairs are also costly. The machines are notoriously complex and require specific mechanical and programming knowledge to repair. The knowledge required takes years to develop and does not come easily.

Remedies for Common Precision CNC Machining Challenges

Fortunately, each challenge has a corresponding remedy. Most of the solutions require educating yourself on how CNC machinery works. Knowledge will allow you to take preventive measures to avoid precision CNC spinning errors. 

Deal with Setting and Tools 

Setting and Tool issues are relatively easy to fix. Consider the following solutions: 

  • Examine the material and decide what tool and setting is appropriate 
  • If a tool is blunt, replace the tool with a sharpened tool 
  • Examine the tool type and adjust the settings accordingly 

Listen for Chatter and Vibration 

When these noises appear, something is wrong. Check these areas if you notice chattering or vibrating: 

  • Adjust the RPM 
  • Use tool holders that are balanced 
  • Check if there is enough lubricant 
  •  Look at CNC machine part positioning
  • Check hydraulic pump and pressure 

Know the Correct Material to Use 

Knowing your metals will help you avoid issues linked to the material. To avoid issues: 

  • Know what material you and your staff can machine well 
  • Know the project 
  • Consider what material will be most efficient based on part function

Address Process and Program Issues 

Processing and programming pitfalls are not easy for new operators to address. An experienced operator that knows coding is best at fixing data issues. However, there are some steps you can take yourself: 

  • Make sure the machine is aligned mechanically 
  • Try turning off the machine and reboot 
  • Technical upgrades
  • Invest in programming training 

The most beneficial fix for an ineffective CNC machine is to upgrade hardware and computer software. 

Take Preventive Measures to Reduce Repairs 

Upfront, CNC machinery is expensive. Small companies may struggle to adjust to the costs of CNC machinery. In the long run, investing in CNC machining will yield profit. 

Repairs are costly and require expertise. To reduce the cost of repairs, make sure you are proactive. Follow these suggestions: 

  • Invest in preventive machine maintenance programs 
  • Make sure technicians know how to operate CNC equipment correctly
  • Regularly check hardware and software 
  • Clean and perform regular maintenance on the machine, often 
  • Check airflow and lube levels

High-speed Machining Formulas and Definitions

Have you ever wondered what high-speed machining is? Are you curious about high-speed machining formulas and definitions?

HSM, also known as trochoidal milling, is all about efficiency. It’s become popular over the last few years, with more and more shops adopting the practice. There have even been some advances in Machine Learning that deal directly with HSM and optimizing your tooling.

This article will explore some of the backgrounds of high-speed machining, how it compares to conventional machining, and touch on some high-speed machining techniques.

Keep reading if you’re curious about the process and how you can apply it to your next project. Then contact Glenn Metalcraft for your heavy metal spinning and other fabrication needs. 

What is High-speed Machining (HSM)?

At its heart, high-speed machining (HSM) is all about increasing material removal rates while decreasing cycle time and improving tool lifetime.

Companies tend to argue about the correct definition of HSM. Some say that the process requires quick milling passes. You may also find the very technical definition — machining at the resonant frequency of the machine. When you break it down, all this means is using spindle speeds that help to minimize chatter.

Even the “High-Speed” part of HSM is disputed. Although generally, HSM is understood to start at 18,000 rpm, various shops have shown that the process can work with slower spindles as well.

Other machinists argue that HSM should deal with high material removal rates only. The argument here is that the true aim of HSM is to give a surface finish that’s good enough after one pass. 

Remarkably, the initial reason HSM became a consideration was the discovery that increasing spindle speed reduces the heat in the cut once you reach a particular point. At the same time, there’s also a change in cutting forces which likely contributes to the lower heat of the cutting edge.

Let’s look at an example using aluminum. At around 300 SFM (surface feet per minute), the surface temperature is approximately 650c or ~1200f. The research shows that at 1000 SFM, you start seeing the same temperatures! Even more interesting, research also shows that there’s a possibility to run faster and get even lower temperatures.

A Few Definitions

You’ll commonly hear a couple of definitions when talking about HSM and you can find a few of them below.

Feeds and Speeds

This phrase will also sometimes show up as “Speeds and Feeds.” In the simplest definition, it refers to the cutting speed and the feed rate. These two terms are often paired up when we talk about CNC cycles, but you can also use them separately.

You’ll usually see this term used alongside calculations for high feed rates and high RPM operations. Feeds and Speeds calculators can help achieve excellent finishes on both sides of the tool’s cutting edge.

Check out the full section on Speeds and Feeds further down.

SFM

SFM stands for surface feet per minute. It’s a reference to how quickly cutting tools move across the surface of a piece in a CNC cycle. Obviously, the speed at which your tool head moves impacts the whole process.

Chip Load

The chip load, otherwise known as “feed per tooth,” is the thickness of the material that gets cut away by each tooth. The chip tends to take away some of the heat with it during the milling process.

We care about this, particularly because with the wrong calculations, you may end up clogging your tool teeth and increasing temperature.

Radial Depths

When talking about the radial depth of a cut (RDOC), machine shops mean the distance a tool steps over into the workpiece. This is also sometimes called Stepover and cut width.

Chip Thinning

Chip thinning generally happens when the RDOC varies. When we talk about chip thinning, we’re talking about the thickness of the chip. Chip thinning occurs when the Chip Load and RDOC are not equal.

An easy way to think of this is to remember that if each tooth is working on the surface at a ninety-degree angle, our cut is most efficient. At that point, the RDOC is at 50% of the cutter diameter.

Below 50% RDOC, the chip thickness changes, and the cut becomes less efficient. This decrease in efficiency can lead to tools wearing down faster than expected and poor quality finishes.

Milling Variables

Beyond the definitions we’ve looked at above, there are some variables used in calculations for CNC machines that you should be aware of. We’ll discuss the formulas themselves a little further down.

  • Speed – Surface Feet per Minute (SFM)
  • Feed – Inches per Minute (IPM)
  • Feed per Tooth (FPT)
  • Adjusted Feed per Tooth – Chip Thinning (AFPT)
  • Feed per Revolution (FPR)
  • Depth of Cut (DOC)
  • Width of Cut (WOC)
  • Tool Diameter (D)
  • # of Teeth in Cutter (Z)
  • Metal Removal Rate – Cubic Inches per Minute (MRR)

High-speed Machining Formulas and Definitions

So how do you calculate optimal speeds and feeds? There are two main equations to use. Read on for more information on each part of the equation and how you can get the information that goes into it.

The first formula looks like this:

Feed Rate = Spindle RPM x Number of Teeth x Chip Load

You’ll need to know the RPMs (revolutions per minute) of your spindle and if you’re unsure, check with your manufacturer. They will have spec sheets that deal with your particular model.

Once you have found all your variables, plug them into the formula to calculate your feed rate.

The second formula for calculating SFM looks like this:

SFM = RPM x Diameter x pi/12

Now that you’ve got your RPM, you can plug the values to this formula to find the SFM.

Finally, if you have your SFM, you can also work back to get your Spindle Speed:

RPM = 12 x SFM / 3.14 x Diameter

Or, if you prefer a more simplified version:

RPM = 3.8 x SFM / Diameter

Expert Machining Done Right

The benefits of high-speed machine tools are quite clear. Now, it’s time to put that knowledge into practice. With a little patience and experience, you’ll find that HSM improves milling efficiency substantially.

Although the high-speed machining formulas and definitions we’ve talked about are fairly standard, they can feel complex and overwhelming. Contact Glenn Metalcraft to discuss full-service metal manufacturing when you’re ready to explore HSM further.

How Long Does Powder Coating Last?

Is your business in route for an upgrade? It’s not uncommon for successful businesses to upgrade components to serve their customers better and bolster their brand. Since you’re reading this, it’s safe to assume that your business is ready to level up and lead the competition.

One of the most important things you can do is add a fresh coat of paint to preserve your equipment and maintain a professional look. One of the best ways to do that is with powder coating. However, you may be wondering, “how long does powder coating last?” You would want your coating to be worth the investment.

Luckily, you’ve come to the right place for answers. This article will show you what you need to know about powder coatings so you’ll know if you should make the right move. Read on to find out more, then reach out to Glenn Metalcraft to discuss your full-service metal manufacturing needs.

So, How Long Does Powder Coating Last?

Powder coating is a powerful substance, but not all coatings are created equal or for the same tasks. Powder coatings vary in strength, application, and usage, all of which will affect the longevity of the coating overall. Here are just a few questions you’ll want to ask yourself that will help determine how long your coating will last.

What Are the Different Types of Powder Coatings?

The most obvious thing to look into is the type of powder coating you plan to use. There are several different types of coatings, but the most common ones are:

  • Polyester coating: a popular coating material used in many interior and exterior applications;
  • Epoxy coating: a super strong and durable material that’s great for indoor usage;
  • Fluoropolymer coating: A highly weather-resistant coating that makes it great for exterior use, and;
  • Urethane coating: A coating similar to polyester but is harder and more resistant to chemicals.

Each type of powder coating offers its own strengths, and by choosing the best one for your needs, you can get the most years out of it.

Also, by applying a pre-treatment solution before you add the coating, you will maximize the lifespan of the coating and keep your equipment looking new for a long time to come!

What Factors Affect the Life of a Coating, and How?

Of course, the lifespan of your powder coating can also be affected by the numerous factors surrounding your business and your application. The first thing to determine is whether you’ll be adding the coating for interior or exterior use. If the item you’re applying the coating to is for outdoor applications, but the powder coating itself is for interior application, you will drastically reduce the lifespan of the coating.

The presence of certain chemicals in the environment could also affect the coating’s lifespan. Although some powder coatings have more resistance to chemicals and corrosion than others, a chemical-laden setting is sure to wear all coatings down at a faster rate.

You’ll also want to factor in the function of the actual machine or part that’s being coated. A stationary machine or component is less likely to wear down the powder coating, while one that’s constantly moving and creating friction and heat will wear the coating down faster.

Complete Guide to Welding Types and What Each Means

What are the Different Types of Welding?

Since ancient Egypt, humans have welded base metal in one way, shape or form. Welding does not get the credit it deserves, but few skills human beings have created have had as much of an impact on the average person’s daily life.

Here are the major welding techniques, how they were or are used. Keep reading to learn how you can determine the types of welding processes you need for any projects you are working on.

And for a quote on welding services, contact Glenn Metalcraft today.

Welding’s Impact

A finished weld.

Just about everywhere you look, various forms of welding affect our lives. Your vehicle, furniture, appliances, even some electronics have some form of welding (which is different from soldering.) From the early days of forge welding through today’s most computer-driven, semi-automatic, and sophisticated welding methods, welding has helped us bond metal to create things that truly enhance our lives.

Forge Welding

Forge welding was the earliest form of welding. It started with ancient Egypt and spawned blacksmithing. It involves heating two metals to the point of a molten status and then pounding them into a single metal object.

Braze Welding

What are the different types of welding? Braze welding is a welding method.

This type of welding goes far back as well. Braze welding has been found in archeological sites worldwide. It was used for bonding bronze, silver, gold, and steel. This type of welding is still used today, primarily when working with softer metals that melt under lower temperatures.

Arc Welding

An industrial welder using the arc welding method.

Arc welding is the most common form of welding and was developed in England and France in the early 1800s. It uses an electrical pulse to melt metal at extremely high temperatures and carry it across a joint via an arc to fill the arc with an incredibly strong bond.

Arc welding came into prominence during World War I and eventually became a primary bonding method in modern manufacturing. In the war (and subsequent wars,) it was a vital tool in repairing ships quickly so they could return to battle or be retrofitted with new equipment.

Arc welding has improved in equipment, safety, cost, and weld quality and is now used in several different forms for various purposes. A few of the more common methods of welding are outlined below.

Metal Inert Gas (MIG) Gas Metal Arc Welding (GMAW)

What are the different types of welding? MIG welding is a type of welding shown here.

MIG welding is exceptionally simple but produces high-quality welds, and because of that, it is a favorite for many new welders. The welding process occurs by feeding wand-based filler metal into the portion of the weld that is arced, while gas expels to shield it from external elements.

It is not generally used to weld metals outside because of the need for a gas shield. It can be used, though, for many different types of thickness, making it a “go-to” for simple type welds. The wire serves as the electrode and melts when the arc travels from the tip of the wire to the base metal. This action creates a pool that hardens into a weld.

The arc process is controlled by the welder, which allows them to proceed at their own pace. When completed, a MIG weld is smooth, tight, and very linear.

Stick Welding Shielded Metal Arc Welding (SMAW)

A welder stick welding.

Stick welding is the most used type of welding for non-complex projects because it is easy to learn, inexpensive, and easy to perfect. The downside to stick welding is that it splatters a lot, depending on the welder’s skill. The splatter makes cleanup afterwards nearly inevitable.

An arc from the stick to the base metal is created, and the stick serves as the filler metal. The arc will generate heat and flux, coat the stick, vaporize, and protect the metal from oxidation. It can be used outdoors and in adverse weather, including rain, ice, snow, and wind. Additionally, stick welding works on rusted, dirty, and painted surfaces.

Another upside to this welding method is that there are many electrode types, and they are easy to swap. This flexibility makes stick welding very versatile and able to work with most metals, including stainless steel. Because the process will create heat, it is not the ideal welding method for thin metals.

TIG – Gas Tungsten Arc Welding (GTAW)

A closeup of TIG welding

This type of welding uses a tungsten electrode and requires no filler metal, meaning that you can join the two metals directly. Shielding gas is needed for this type of welding, and it protects the weld from external elements. There is no splatter, and the bond is incredibly precise.

Flux Cored Arc Welding (FCAW)

Flux Cored Arc Welding at a construction site.

FCAW uses a wire as the electrode, which has a core of flux that creates a gas shield around the weld. FCAW is best with thicker, heavier metals, making it a favorite for repairing heavy equipment and components with large metal seams, like barges. The FCAW process is clean, does not need external gas, and is affordable.

Plasma Arc Welding

A smaller arc helps create a very precision-oriented weld with Plasma Arc Welding. This method also uses a different type of torch, which runs much hotter than a traditional torch. The torch is so hot that even base metals can melt, allowing plasma welding with no filler metal.

Plasma Arc welding creates deep weld penetration on relatively narrow weld channels. Plasma Arc Welding produces attractive welds that are exceptionally strong. It can also be accomplished at very high speeds, making it ideal for some forms of manufacturing.

Other Types of Welding

While the welding methods outlined above are the most popular, several other types of welding are also frequently used. Each of these methods are used in hybrid situations, usually in some form of manufacturing. A few include:

  • Laser Beam Welding
  • Electron Beam Welding
  • Electroslag
  • Atomic Hydrogen Welding

What are the Different Types of Welding: Final Thoughts

A welder working.

Generally, the two most popular types of welding, stick, and MIG (GMAW), are used because they are easy, require little specialized equipment, are inexpensive, and the weld produced is superior and great looking. They are the most popular because anyone from beginner to expert can do them with little training time.

CNC Machining vs 3D Printing

Choosing between CNC machining and 3D printing is a common question for anyone looking to create metal products. Both machines produce a wide range of metal parts and offer unique perks. However, not every business will benefit from using both, and the wrong choice could cost you in terms of quality and money. How do you know which manufacturing process your company should invest in? 

This guide will take a look at everything you need to know when comparing CNC vs 3D printing. It will help you make an informed decision and choose a process that’s better suited for your needs. In the end, if you decide you need a reliable expert for your metal parts production, call Glenn Metalcraft to have your parts shipped directly to you.

CNC Machining Basics

A CNC milling machine. CNC Machining VS 3D printing

CNC stands for Computer Numerical Control. An engineer designs software to guide the CNC machine to build parts. Because the part is built by software and machines, the entire process is very precise. 

CNC machines are capable of producing parts through a process of subtractive manufacturing. With subtractive manufacturing, machines take a block of material and remove (subtract) pieces to form the final metal component. 

CNC machining has been around since the 1950s, which makes it a traditional manufacturing process. However, the original technology has been improving ever since. For example, companies like Glenn Metalcraft now operate on 6-axis machines, making the process quick, efficient, and highly accurate. 

With machines like the HAAS R2000IB 165R, Glenn Metalcraft can handle large payloads and functions such as: 

  • Material handling
  • Drilling
  • Tooling
  • Press tending
  • Spot welding
  • Assembly

3D Printing Basics

A 3d printing machine creating a product. CNC Machining VS 3D printing

One of the biggest differences in CNC vs 3D printing is simply how it works. As mentioned before, CNC machining is subtractive. However, a 3D printer functions as an additive machining process without support structures. 

With the additive machining of a 3D printer, metals are added layer by layer to build parts. First introduced in the 1980s, it has become more prominent and common in recent years. 

3D printing also uses software to build metal parts, but its capabilities in terms of size and handling are limited compared to those of CNC machines.

CNC Machining vs 3D Printing: How To Choose

Metal automotive parts created with CNC machining, not 3D printing.

As you learn how the two manufacturing processes work, you may already start to realize which is right for you. Here are some key differences between the two options to take into account when considering CNC vs 3D printing.

Speed

When it comes to large orders, nothing beats computer numerical control. These machines reduce the need for operators as they can handle much of the process from beginning to end. They can also handle large pieces on their own and work quickly from one part to the next. 

While a 3D printer can be fast, it can’t produce large bulk orders as quickly and only takes on what fits on the printer bed. So when you need a large order done accurately and speedily, CNC machining may be the better option for you. 

Price

You may not see any difference in price per unit between the two manufacturing processes for some smaller orders. However, for large orders, CNC machining’s speed makes it more cost-effective. Because large quantities are so well handled by the CNC process, you won’t see a significant increase for a large-scale project.

If you’re truly on the fence between 3D printing and CNC, get some quotes from various experts to better understand how your specific order may affect the prices. As a rule of thumb, medium to large-sized orders will get lower prices from CNC machining engineers. 

Size

You can get it all taken care of, from the smallest to the biggest metal parts, by CNC machines. This is because the equipment is made to handle any large block of material and turn it into the final product. These machines are even used to make metal parts for automobiles. 

If you want a large metal part fabricated, it will be far easier to find engineers with the right CNC machines. 

On the other hand, a 3D printed part is limited to the equipment’s size, which is currently significantly smaller than today’s standard CNC machines. While you might find large 3D printing equipment, you will have to shop around. And, it’s not by any means a guarantee that you’ll find what you need. 

Precision

When you send out to have parts created, you want the most professional final product. It won’t do to have jagged surfaces where filaments were laid imperfectly. So when considering whether to choose 3D printing vs CNC manufacturing, know that the 3D printer will work best for less precise components. 

Computer numerical control metal 3D spinning is the way to go for the smoothest surfaces and cleanest lines — it gives you the best results. Any parts needing a tightly toleranced surface, such as key components or tools, require a ready-to-use finish best provided by CNC manufacturing.

Both CNC machining and 3D printing have their own merits. However, one will be better for your project and company’s manufacturing needs than the other.

CNC machining offers a cost-effective, precise, and quick manufacturing process if you’re producing on a large scale. If you’re only looking for a small batch of parts that don’t require the highest quality finish, a 3D printer may give you exactly what you’re looking for at the lowest price.

Take Advantage of the Flexibility of CNC Machine Capabilities

If you’re looking for the best machined part services, then computer numerical controlled machining (CNC) is the best process for you. Manufacturing any product you need has never been easier with modern CNC machine capabilities. Today’s latest models make it possible to produce more quickly and affordably while providing a highly accurate product. 

CNC machining also offers a wide range of potential features to customers. At Glenn Metalcraft Inc., we specialize in the best CNC machining equipment, operators, tools, and standards to provide high-quality services to our customers. Here are some reasons we love CNC machining and why you should take advantage of these revolutionary products. And if you want to learn more about our manufacturing processes and what we can do for your machining needs, you can reach out to us today. 

CNC Machine Capabilities

A CNC machine lathe

The CNC in CNC machining refers to “computer numerical control.” This phrase means that, rather than a human directly handling the cutting tools and operations, a computer or CNC program controls the machining. As a result, the computer can control every aspect of the machining process, from replacing cutting tools to welding. 

CNC lathes can cut far more precisely than humans can. As a result, they can also handle more dangerous tasks without concern for team member safety. CNC manufacturing processes are only becoming more efficient as the software continues to improve each year and enhance the quality of manufactured parts.

There are many benefits to using CNC machine capabilities for your manufacturing. Here are just a few:

Tasks are accomplished at high speed. 

Computers remain focused on the task at hand, need fewer breaks, and make fewer mistakes. All these factors mean that the machinery will perform tasks more quickly. So, you can expect faster completion times and increased productivity.

Accuracy. 

With humans, there is often room left for human error. After all, people make mistakes. 

But computer-aided design (CAD) means that accuracy is far higher. In fact, it can almost perfectly replicate a template to the accuracy of 1/1,000th of a unit. So you can trust you’re getting what you want from the software and its robotic tools. 

Lower maintenance. 

When you hire companies like Glenn Metalcraft Inc., you may not notice that CNC devices need less maintenance compared to other manufacturing processes. But you will see the difference reflected in fast turnaround times and an affordable rate. 

Large projects accomplished safely. 

Computer-aided design (CAD) software is not only accurate and fast, but the tools themselves can handle large pieces of metal and complex tasks. Fabrication of a large part or specific tasks may pose a danger to staff, but a powerful machine can accomplish the task at hand safely with great accuracy. 

Not sure if CNC machining is right for the part you need to be created? Talk with the engineers at Glenn Metalcraft Inc. and ask what we recommend for this process. 

Multi-Axis Power

A CNC machine at work

There are various types of CNC machines. Each machine can accomplish tasks differently. For example, CNC turning vs. milling is two ways of handling materials to produce a part. The difference is that turning requires the material to move, whereas milling means that the machine’s parts move around the material. 

But in addition to techniques used, you also have options for how many axes a machine has. With more axes come greater CNC machine capabilities. That’s because each axis allows for more movements, allowing the robotic mechanisms to move precisely to accomplish the function required. 

People who are familiar with CNC machine capabilities are most familiar with 3 and 5-axis units. After the 3-axis and 4-axis designs, the 5-axis showcased a significant improvement in machine competency. But people didn’t stop at the 5-axis, and units continue to improve to this day. 

The Benefits of 6-Axis CNC Machining Tools

Welding

6 Benefits of Robotic Welding

Automated welding offers several advantages to businesses, including reduced costs and higher return on investment. This article discusses the many benefits of robotic welding and how it can help your business. 

What are the Benefits of Robotic Welding?

1. Increased Productivity

Compared to manual welding, robotic welding systems can achieve faster results. 

It can improve productivity as the robotic systems get the job done quickly. You don’t have to wait hours when you have robots working—the cycle time is lesser, which means you can get more things done. 

Whether you have acquired new or used robots, the output is still the same as long as the purchased robotic welding systems are functional and in good working order or when you hire the right company to help you with fulfillment. Most importantly, robot arms don’t get tired. There’s no need for breaks.

You can have welding robots work as many hours as possible if you have several projects that need to get done. No one has to take vacations or sick leaves. If you’re flexible or have some people who can supervise, your robotic welding systems can work 24/7. 

2. Reduced Mistakes

With manual welding, it’s possible to make mistakes. 

Robotic systems, on the other hand, are designed to work effectively and efficiently. So long as the machines are well maintained and in good working condition, they make fewer to no mistakes. 

The weld quality will be exceptional with industrial robots. You don’t have to worry about manual welders’ common mistakes, such as choosing the wrong wires or the size gun or using the incorrect voltage. These mistakes are reduced significantly, which in return benefits your company. 

3. Consistency

Welding processes are used in several industries such as construction and automotive. 

Before the process can begin, a welding method is chosen. The base metals and equipment are prepped, measured, and positioned. Also, the welder has to be certified, prepared, and trained. They need to adhere to the standard procedures to ensure consistency and also avoid contamination. 

When the worker fails to do proper shielding, the result could be weak or porous. You can significantly reduce or completely avoid the problems associated with manual welding when you automate the process. 

With robotic arms helping, you know that the output is always consistent. You won’t have to worry about other issues or contamination. Robotic automation ensures high-quality output and consistency all of the time. 

4. Safety and Cost Savings

When it comes to welding, safety is the topmost priority. 

Welding injuries can occur when the workers don’t take the proper precautions, such as wearing safety glasses, safety boots, welding helmets, and hearing protection. When the welder isn’t careful, they could lose their hearing or eyesight and suffer general burns. 

It’s essential to keep all the laborers safe, or the company may pay for the medical bills or other damages if the laborer isn’t insured. You can avoid all these when with the robotic welding process. Robot arms don’t get hurt, and you won’t have to pay for insurance when you have people working for you. Over time, it can add to massive savings on your part. 

Keep in mind that running a business means reducing all the expenses wherever possible to maximize your profit. A higher return of investment is entirely possible with automated welding.

The cost to acquire robots may be higher, but it’s cost-effective in the long run. So long as you know how to maintain your robots properly, they should work efficiently for many years, helping you generate more revenue for your business. 

5. Robots Can Start Immediately

Whether you’re a startup or an established business, it’s essential to have a good hiring process in place to ensure that you have the right people in your team. 

Welding requires the right skill and concentration — you can’t hire anyone for this. They need to have the training and experience for them to work efficiently and effectively. Also, you will, of course, need to pay for labor. 

You can save time when you have robots working for you. There’s no need to spend weeks or months looking for more people to help you finish projects if you’re an established company. 

No more labor costs too, which is one of the benefits of robotic welding. Most importantly, you don’t have to wait for them to get started. Robots can begin working on your project at any time—no need for training or hiring process. Robots are already designed to do their job the best way possible. 

6. High-Quality Output

When the workers are not highly trained or experienced, they may make mistakes or even injure themselves. Major defects can include hot and cold cracking, blowholes, penetration defects, or iron contamination. 

Before starting the process, welders need to do some preparation, take extra precautions, store and handle metal the right way, choose the right gun and electrodes, etc. If they fail, the output may not be that exceptional. 

With automated welding, the output will be of top-notch quality if you have the best robots in the market. In return, you get repeat clients.

Superior Metal Spinning

Metal Industry lathe machine work

Metal spinning, also called spin forming, spinning, or metal turning is the process of rotating a tube or disc of metal at a high speed and applying localized pressure to shape the metal, which is similar to the method used in clay pottery. The process, which creates an axially symmetrical product, can be done by hand or performed by a machine.

Artisans and commercial companies use metal spinning to produce high-quality metal parts for various industries, including home goods, science and technology, and automobiles.

The metal spinning process is cost-effective and produces very little material waste. 

Any form of ductile metal can be used in metal spinning, such as aluminum, stainless steel, carbon steel, copper, brass, Hastelloy, Inconel, and titanium. The diameter for metal spun through this process can range between one inch to eight feet.

How Does It Work?

Examples of spinning tools litter history. The Ancient Egyptians used manual spinning techniques to create everyday tools or build architectural masterpieces. The process shifted in the Middle Ages to metalwork and would eventually become the machine-operated precision heavy gauge metal spinning it is today.

To begin the spinning process with a CNC machine, a pre-cut sheet of metal also called a blank, is clamped between the mandrel and tailstock of the spinning machine. A primary drive rotates the mandrel and tailstock as a spinning roller performs a series of passes over the block to change its shape.

A skilled hand spinner can also manually spin and shape a piece of metal by applying a roller by hand.

Laser Cutting

LASER CUTTING IS COST EFFECTIVE

Laser cutting has replaced some of the most conventional cutting methods in the fabrication process. A combination of high-powered laser beams, partial mirrors, and gases combine to form modern laser cutting machines. Recent developments have led to laser cutters using CNC technology to cut through steel or piping many inches thick with a smooth cut line and fine detail.

How Laser Cutting Works

precision laser cutting machine

Laser cutting directs the output of a high-powered laser via computer toward the material to be cut. The material then either melts, burns, vaporizes, or is blown away by a gas jet, leaving the edge with a smooth, high-quality surface finish. Industrial laser cutters can cut flat-sheet material as well as structural and piping materials.

At Glenn Metalcraft, we’ve been using our expertise and experience manufacturing a precision laser-cut part that meets our customer’s exact specifications for over 35 years. Need our expertise?

Advantages of Laser Cutting

Laser cutting is versatile and can implement cutting in ways that other machines can’t. Materials that are difficult to cut using other methods make excellent candidates for laser cutting. The advantages of laser cutting include:

  • High Accuracy. Accuracy of +/-0.1 mm allows achieving high precision cuts.
  • Low lead times. No need to change the setup for cutting a lot of different shapes within the same material thickness.
  • Lower power consumption. Cutting speed is faster than traditional mechanical cutting methods resulting in less power consumption.
  • Less waste. High processing speed results in a minimal heat-affected zone, ensuring low rates of workpiece distortion.
  • Ability to handle complex jobs. Capable of producing custom shapes and complex geometries.
  • Consistent part quality. Since laser cutting machines are CNC-controlled, they can repeatedly and consistently produce complex and intricate parts to high tolerances.
  • Less damage. Reduced risk of tool marks and surface scratches due to lack of physical contact.
  • No need for finishing. High-quality cuts and edges don’t require cleaning, treating, or finishing.
  • Suitable for a variety of metals. Laser cutting works on a wide array of metals like Steel, Titanium, Brass, Copper, Nickel, Tungsten, Nickel, Aluminum, etc.

Applications for Laser Cutting

Lasers are a vital part of the automation process across the automotive, electronics, energy, heavy equipment, medical device manufacturing, and tool & die industries. The use of laser cutting in the manufacturing process can significantly reduce overtime on projects and increase productivity.

Automotive

As vehicles become more advanced, smaller parts need to be precisely cut. The smooth, precise cuts created by a laser allow for less material waste, and the power required for laser cutting is low. The automotive industry has a significant need for exact replicas of parts of different shapes and sizes. Laser cutting cuts metals to form body pieces of the vehicle, electronic components, and interior covers and buttons.

Laser cutting is ideal for cutting complex formed parts. These are usually vital parts that lend support to the structure of the vehicles. Commonly, these pieces create the engine frame or the instrument panels.

Electronics

The trend toward miniaturization, more efficient use of space and large volume production are highly valued characteristics in the electronics industry. Laser cutting technology can produce the precision and high-speed production required for switching cabinet housing, plug-in units, and the housing of electrical devices.

Energy

Changes in building use are increasing the demand for custom solutions for unique purpose buildings, which require flexible machine concepts from manufacturers. Many products used in making air conditioning technology and energy technology are created from sheet metal such as housings, vents, and ductwork.

Heavy Equipment

From large part processing and thick plate cutting to exact and small, intricate parts, laser cutting can be used in many applications to maximize efficiency. Laser cutting provides a cost-effective alternative to building expensive dies to customize pieces.

Laser cutting is an ideal choice for a full range of agricultural, construction, and heavy equipment industry needs. Structural frames, exhaust pipes, driver’s cabs, mounts, blades, and brackets in agricultural and construction machinery are made from sheet metal.

Medical Device Manufacturing

Laser-cut stainless steel is the basis for medical devices and instruments that improve the procedures used with patients. Scalpels, scissors, valve framers, vascular clips, bone reamers, flexible shafts, and hones are all manufactured laser-cut precision parts.

Tool & Die

The laser’s ability to cut different depths of metal makes it ideal for cutting an extremely accurate die for stamping pieces and molds that will endure the repetitive nature of die-cutting. Laser cutting makes replicating the die a quick and precise operation.

Laser cutting can make injection molds with the same accuracy that it does with dies. Laser cutting simplifies mold making and makes reproducing the mold precisely a much less time-consuming and costly endeavor.
