Here’s What You Need To Know About CNC Metal Cutting Machines

CNC metal cutting machines are automated machines used for manufacturing parts and components. The cutting process uses software programs to cut a metal sheet into specific shapes and sizes. Hence the name, CNC, or Computer Numeric Control. Software programs are input into the machine and turned into code used to cut out the designs. 

A CNC metal cutting machine offers a more dynamic way of cutting parts and components. It can cut more complex designs with a higher degree of accuracy and precision. It’s why there are countless applications for CNC machines in a wide number of industries. They are used to fabricate automotive and motorcycle parts. They are used to manufacture aerospace and defense equipment. CNC machines fabricate medical components and tools, plastic products, and more.

Can CNC Metal Cutting Machines Work On Everything? A Few Advantages and Limitations

As your business grows, you’ll need to improve your production process. Getting new equipment or upgrades will help you take on more projects.

In both cases, a CNC metal cutting machine delivers speed, precision, and cost-effectiveness. You’ll need a nexAir CNC metal-cutting machine that will give you advantages like:


CNC metal-cutting machines are cheaper to operate than traditional fabrication machines. For lathe or milling machines, you’ll need one operator each. A well-trained CNC operator can oversee several machines at the same time. Furthermore, you save time and raw materials. CNC machines are precise and accurate. You don’t have to waste time fixing errors, and you won’t produce a lot of material waste.

Accuracy and Consistent Quality 

CNC machining is more precise than manual techniques. Even better, it is repeatable without a decline in accuracy or quality. You can produce more workpieces faster and be confident that each piece is as precise as the one before.

Increased Production, Speed, and Efficiency 

CNC machines use computer programs for process automation. They increase operator control and make the metal-cutting process faster and more efficient. Even pre-cutting prep is shorter and faster.

Workplace Safety

Operating a CNC machine isn’t as risky as a lathe or milling machine. Workplace accidents are reduced because CNC machines have many safety redundancies. They have machining guards, transparent doors, automatic shutoff switches, and more.

Despite its advantages, your CNC metal-cutting machine has limitations to what it can do, including:

High Initial Investment Cost

The initial cost of getting a CNC metal-cutting machine can vary depending on the type that you get. Many owners attest that a CNC machine’s consistency and quick turnaround times mitigate its cost. Its precision and high productivity rate help with return on investment. But it doesn’t detract from the fact that it is an expensive piece of equipment to invest in.

Limited Scope and Restrictions for Materials and Workpiece Size

Each CNC metal cutting machine is specific to operations and materials that it can cut. For example: if you have CNC metal-cutting machine that uses a plasma torch, you can only use it for metal fabrication. You won’t be able to redeploy it for other projects that use wood, composite materials, or plastics.

Another limitation is the output size. Most workpieces made using a CNC are limited by the machine’s size and cutting tool. Your designs can be as complex as possible but their sizes are limited to a specific range. Even if you do get or rent larger-than-average CNC machines, you’ll still be limited.

Required Training 

All CNC metal cutting machines require training to use. It isn’t a plug-and-play setup and will need certification to operate. Operators will be required to train in computer-aided design. They will also be required to learn how to operate CNC machines. Many of our clients assign two-man teams to work on their CNC metal-cutting machine lines. One person is in charge of programming the designs into code. The other person is there to operate the machines. Smaller facilities often have only one person executing these tasks for one or more CNC machines.

Production Compatibility is Not Guaranteed

You may find compatibility issues with your current setup and your new CNC metal cutting machine. Or, between two different CNC models. In cases like these, you may want to call on nexAir to help you assess what needs to be done. There could be many factors that would cause these compatibility issues—or simply one.

A CNC metal cutting machine can help take your business to the next level. But it’s important to consider both the advantage and limitations of having one.

If you’re unsure of what choice is best for you, please let us know. Consulting with our nexAir experts help you as you consider all your options. nexAir CNC Plasma Cutting system, for example, is a great machine to get because it can cut metals like steel, stainless steel, and aluminum, among others, with ease. It uses a powerful plasma torch (up to 50,000 degrees Fahrenheit) for clean and precise cuts. But, its most prominent feature is also its biggest limitation: it can only work on metals. So please do let us know how we can help. Let’s assess your production requirements and how nexAir can help boost your timelines and delivery.

Is a nexAir CNC plasma cutting system right for you?

What Materials Can Be Used in CNC Machining?

In a nutshell: a lot. There’s a big caveat though. There are many types of CNC machines. Each type can cut a variety of materials. You need to know which CNC machine you need for your requirements and the materials you work on before you make your purchase. Check out the section next section. We’ve outlined the three most common CNC machines used for materials cutting. 

In the case of CNC metal cutting machines, you have a lot of options. nexAir’s CNC plasma cutting systems, for example, are used to cut a wide range of metals. Some of the most commonly used metals aluminum, stainless steel, nickel, carbon steel, titanium, and metal alloys. Of these materials, aluminum 6061 and 7075 are the two grades most typically used with CNC plasma cutting systems. Both metals have great strength-to-weight ratios, durability, versatility, and corrosion resistance. Using nexAir’s CNC plasma cutting systems, you can cut these metals for auto components, aircraft parts, and more.

Plasma and Oxyfuel Cutting Versus Laser Cutting: Here’s Why Your Business and Materials Decide the CNC You Need

CNC metal-cutting machines are essential in engineering and fabrication. Within this area is a CNC technique called thermal cutting. It’s reliable for many applications. Thermal cutting comes in three types: plasma, oxyfuel, and laser cutting. 

Quality and Cost

The CNC plasma cutting machine is a workhorse and cuts metals of up to two inches in thickness. Cost-wise, it will depend on size and functionality. ROI periods can range from around three to six months, depending on your rate of throughput. 

Oxyfuel metal cutting is highly favored for its quickness and high throughput. But it is limited to carbon steels only. Cost-wise, oxyfuel-cutting CNC machines are the most affordable, if not the most versatile. 

Laser-cutting CNCs can cut through all types of metals. However, its effectiveness is limited by material thickness (up to 1/4 inch only). Also, the CNC laser cutter is the most expensive of the three. But because of its precision, and high tolerances, it is favored in the medical industry, precision equipment and tooling, and jewelry. 

Productivity, Speed and Flexibility

In terms of production, CNC plasma-cutting machines outdo both oxyfuel and laser-cutting machines. They can churn out more workpieces per hour. They can be used for a wide range of functionalities. Plus, CNC plasmas cutters are the easiest to install and train for.  

Would CNC oxyfuel cutting machines measure up to plasma cutters? In terms of speed and productivity, it can handle itself very well. Combined with its low initial cost and speed, an oxyfuel cutter can give you lots of value. But in terms of cutting materials, it is sorely limited because it only works with carbon steel This is one metal-cutting CNC system that needs to stay in its lane. 

CNC laser cutting machines are ideal for fine work. Its rate of production, however, is not as high as CNC plasma cutting machines. So if you’re considering it for mass manufacturing, it may not be a good idea. 

Choosing your CNC metal cutting system boils down to your fabrication and production needs and timelines. That’s why here at nexAir, we help clients like you by helping you decide which system would help you achieve your production goals. Be it a plasma, oxyfuel, or laser-cutting CNC machine.

Is the Level of Skill Required To Operate CNC Cutting Machines That Important?

CNC sheet metal cutting machines require highly technical knowledge and experience. That’s why here at nexAir, we offer training and refresher courses. We offer guides to help your team get up to speed on our best CNC metal cutting machines. We also provide resources to help operators refresh their knowledge and skills on the latest equipment updates.
