Although CNC laser cutters have become an integrated term, laser cutting and CNC technology differ. Laser cutters are machines that can cut through various materials using high-powered lasers.

On the other hand, CNC or computer numerical control machines are used to accurately control the movement of various tools using computer programs. The purpose is to achieve highly accurate performance that is otherwise impossible to perform manually.

So when these two technologies are combined, we get super accurate CNC laser cutting machines that we can use to cut anything, implement exact design and engraving at an impressive speed, etc. This article will discuss how CNC machining has revolutionized laser cutting. Let’s go!

Introduction To Laser Cutting And CNC Machining 

Before you learn how laser cutting and CNC machining are working together to bring revolutionizing change in varying industries, you first have to know how they differ. So, let us take a quick look at these two processing technologies. 

Laser Cutting

Laser cutting is exactly what it sounds like, using a laser to cut things. But these lasers are not the ordinary ones we see in kids’ toys, music concerts, or laser light shows. They are high-powered and precise and can cut through various materials.

The laser cutting machine produces laser light inside a closed chamber. Then, the light intensifies and becomes strong enough to cut through materials. It’s an elaborate process; you can find details about it here.

However, you have to be precise to cut things using a laser cutter. You have to be so accurate that it is barely possible for humans. The precision and accuracy have to be inhuman. That’s where CNC machining comes into play.

CNC Machining

CNC machining stands for computer numerical control. It is a computerized system where the machine is preprogrammed to move in a predetermined path. The purpose of CNC machining is to ensure precise movement.

As we have said above, laser cutting requires precise control, which is impossible to achieve by human hands. CNC machining overcomes these limitations of manual control and provides impeccable accuracy. So, as you can understand, for precision laser cutting, the incorporation of CNC machining with laser cutting is much needed.

Here is an example of highly accurate CNC laser cutting:

How Do Laser Cutting And CNC Machining Make A Perfect Pair?

Laser cutting and CNC machining can complement each other in manufacturing processes by leveraging their respective strengths. Laser cutting is ideal for its precision and ability to cut intricate shapes. At the same time, CNC machining is effective for materials and details that may not be suitable for laser cutting alone.

Manufacturers can achieve broader capabilities and produce complex parts and components by combining laser cutting and CNC machining. Laser cutting can be used to create initial shapes and cutouts, while CNC machining can further refine and sculpt the workpiece. This collaborative approach allows for greater flexibility and efficiency in manufacturing processes.

Industries such as automotive, aerospace, and many others benefit from combining laser cutting and CNC machining. The automotive industry has been revolutionized thanks to various modern inventions like laser CNC cutters. Utilizing both technologies enables manufacturers to tackle a variety of materials, thicknesses, and intricate details, making it a versatile solution for their manufacturing needs.

Why Is CNC Machining So Advantageous For Laser Cutting?

The popularity and accuracy of laser cutting stem mainly from the development of CNC machines. Everything a laser cutter offers nowadays comes from modern CNC machining technology. Here are some reasons why CNC machining is so advantageous for laser cutting:

Speed

You can cut at high speed using CNC laser cutting machines. Computer programs quickly operate the laser cutter nozzle without compromising quality or jeopardizing safety.

When we cut various things manually using multiple cutting tools, we can cut with precision but at a compromised speed. If you want speed and accuracy simultaneously, nothing beats laser CNC cutters.

Accuracy

Accuracy matters little when cutting a piece of metal or wood into two parts. But accuracy is the most critical aspect when engraving detailed designs on something (a piece of metal, wood, etc.). Before there were laser cutters, hand engraving was a thing.

But that was difficult, time-consuming, and less accurate. You can cut with utmost accuracy with laser CNC cutting machines without compromising speed. Laser engraving is becoming more popular every day, and the incorporation of CNC machines is the reason behind that.

 Safety

Laser cutters are not safe for manual use. Something that can cut through metal or wood can easily cut through human muscle or bone. If something goes wrong, laser cutter machines can become life-threatening.

CNC machining allows remote control of the laser cutter. You have to program the machine to cut or design your desired shape. The CNC machine will take care of the rest. CNC machining technology pairs with various cutting technologies such as lasers, water jets, etc. It has increased efficiency, accuracy, ease of use, and safety all at the same time.

Automation

One major advantage of CNC machining is its ability to automate the laser cutting process. CNC systems are programmed to follow specific cutting paths.

Computer programming eliminates the need for manual intervention. This automation minimizes the chances of human error which leads to improved efficiency and productivity in laser cutting operations.

Flexibility

CNC machines offer a high level of flexibility in laser cutting. They can easily switch between different patterns, shapes, and sizes without requiring manual adjustments.

This versatility makes CNC machining suitable for a wide range of applications in various industries. Industries like jewelry, metal fabrication, automobile, prototyping, etc. benefit from CNC laser cutting.

Conclusion

Laser-cutting technology has undoubtedly revolutionized CNC machining in numerous ways. Its ability to produce precise and intricate cuts and its versatility in working with a wide range of materials has made it a game-changer in the manufacturing industry. 

With continuous advancements in laser technology, we can only expect further innovation and growth in CNC machining. As more enterprises adopt laser cutting technology, the possibilities for design and manufacturing will continue to expand, ultimately shaping the future of CNC machining.
