What is a CNC Laser Cutter? How Does a CNC Laser Cutter Work? 

CNC is an abbreviation for Computerized Numerical Control, which means controlling any machine through pre-programmed software. With that being said, the user has to give commands and instructions through a diagram, file, code, etc., and the machine does the rest of the job itself.

A special language is used to command CNC, which is generally known as CNC programming language, such as G-code. The program is stored in the memory of the machine control unit from where it is executed. 

Any machine that has CNC is called a CNC machine. It could be a router, lathe, grinder, laser machine, etc. Thus, a CNC laser cutter is a laser machine controlled through software. It makes laser cutting automated in every aspect.

For laser cutting, you need to provide the design to the machine. The design can be made on the native software of the laser cutter or design software like Adobe Illustrator, CorelDraw, Inkscape, etc. Then, the design file is converted into a specific format that is compatible with the software. The file is known as a laser-cut file

When the laser-cut file is imported, the laser is started, and the movement of the laser module is controlled according to the design and other settings.

Advantages of CNC Laser Cutting 

1. Automation

A CNC laser cutter automates the whole process of cutting the material. From the laser movement to the speed of the laser, everything is controlled by the machine. Therefore, the user has to do nothing after assigning the task to it. 

With that being said, it is quite easy to operate and handle a CNC laser cutter. Most importantly, there is less manpower required, so the cost of cutting is greatly reduced.

2. Accuracy and Precision

The power, speed, and movement of CNC laser machines are controlled by software. The accuracy can be in fractions of millimeters. It does not matter how many times you try to cut a design; you get identical results. Even if you do multiple passes on the same design, there won't be any errors.

It is an ideal option for cutting vector graphics. You won't get such accuracy and precision through a power tool, such as a jigsaw or circular saw. Most importantly, CNC laser cutting machines have a very fine laser spot, which ensures minimal Kerf width. It is possible to cut designs and patterns that have fine details.

3. Quick Results

CNC laser cutters are much faster than other power tools because of their automation and powerful laser. They save a lot of time. When the laser falls on the material, the temperature is increased abruptly. The material is turned into vapors in no time. Therefore, the machine is capable of cutting materials at an exceptional speed. 

Some machines cut at the speed of even 1000 mm/s, depending on their specifications. You can even cut materials 10-20mm thick in only one pass and a few seconds, depending on the size. For scaling a business and improving productivity, it is better to switch to a CNC laser cutting machine. It will not only save time but also save money.

4.  Safety

If we consider blade-cutting tools, they need special care and attention while handling. Any mistake can lead to an injury. Although there are safety gears and gadgets, safety is still a major concern. For beginners, it is a big no. On the other hand, CNC laser cutters are quite safe. There is no human involvement during the cutting process.

5. Minimal Waste

Laser cutting produces minimal waste. If you use a CNC router, saw, or any other mechanical tool, you will have a lot of waste. CNC laser cutting works by vaporizing the material, which produces almost no waste. The smoke and the particles produced after cutting are expelled through an exhaust. You can also connect an air purifier to clean the exhaust air. 

Secondly, the dimensions of the laser beams are minimal. Therefore, the kerf width is minimal. It will not only reduce waste but also save the material.

6. No Wear and Tear on the Material

When you cut any object using a mechanical tool, such as a saw, router, etc., the material suffers from wear and tear. The edges of the cutting and the left-out material are not as smooth as you want. You need to use sandpaper for finishing.

A CNC laser cutting machine does not create physical contact with the object. Due to no physical contact, there is no wear and tear. You get an exceptional finish, and the left-out material can be used later.

Types of CNC Laser Cutters

CNC Diode Laser Cutting Machines

A CNC diode laser cutting machine is powered by diode modules that emit laser beams having a wavelength of 450-455nm. It is also called blue laser because of its color. The best thing about these machines is that they are available at an affordable price. You can easily find a desktop CNC diode laser for $500 to $2,000, depending on the features. These machines are great for DIY purposes and small businesses. 

The desktop diode cutting lasers can cut 5-20mm materials in only one pass. If you want to cut wood and acrylic, it is an excellent option. But keep in mind these lasers cannot cut transparent and blue acrylic.

CNC CO2 Laser Cutting Machines

A CNC CO2 laser cutter is the next option after diode laser machines. It is a bit expensive due to its technology and immense power. It uses a CO2 laser tube that emits laser beams. These machines are more powerful than diode lasers. Due to high power, the cutting speed is exceptional. They are ideal for cutting a wide range of non-metals. 

CO2 lasers are easily available in desktop and industrial sizes. The cost of a desktop CO2 laser machine can be $3,000 to $6,000, depending on the features. In contrast, industrial or large CNC laser cutters are over $10,000. For small businesses, home use, hobbyists, and DIY purposes, a desktop laser machine is more than enough.

CNC Fiber Laser Cutting Machines

If you want to cut metals, you need to get a CNC fiber laser cutting machine that is designed for metal cutting. Fiber laser machines are quite powerful.
