What Is CNC Laser Cutting Machine?
A CNC laser cutting machine is a piece of technology that vaporizes, melts, or otherwise progressively removes material using laser beams as the primary cutting tool. Computer numerical control, often known as CNC, is a technology that enables a machine to employ optical, an assist gas, and a navigation system to guide and center a laser beam onto the material.
They are pretty well-known for their exact cuts. Even though laser cutting has existed for many decades, CNC has introduced not long ago and is used by many. CNC depends on a computer program to perform its functions, much like any other system technology. This system does the cutting by executing several G-Code operations in sequence.
How Does a CNC Laser Cutting Machine Work?
The operation of the laser cutting machine happens by focusing a powerful laser beam, which gets controlled by computer numerical control (CNC) in the direction of the material. The laser beam gets navigated with the help of the optics and the CNC. There are other navigation methods, such as collimation, adaptive optics, and constant beam length axis. CNC laser-cutting machines depend on CNC’s functionality to deliver instructions to conduct the cutting sequence.
In addition to being a non-contact, thermally based technique, the CNC laser cutting process is also a very efficient method for laser cutting. A laser-focusing lens and a nozzle are both incorporated inside a laser head, which is the component responsible for carrying out this process. The combination of these things produces a concentrated laser beam. After that, computer numerical control (CNC) regulates the motion sequence, enabling you to form the material according to the design of your choice.
Types of CNC Laser Cutting Machines?
It is possible to categorize different types of CNC laser cutters according to the state of the operating laser medium. Therefore, when it comes to different kinds of CNC lasers, the most common are: the CNC Fiber Laser, the CNC CO2 Laser, and the CNC Crystal Laser.
These specific laser cutters use computer numerical control (CNC) technology to supply you with the incredible finishing you need on the cut. Here is a list of the following types you can get in the market.
- CNC Plasma Cutting
- CNC Laser Cutting
- CNC CO2 Laser Cutting
- CNC Crystal Cutting
- CNC Flying Optics Machines
- CNC Neodymium-doped yttrium aluminum ganet.
The few types of laser-cutting technologies that are now accessible across the industry are summarized above. However, the three primary CNC machines are:
CNC Fiber Lasers
This laser machine uses a method that generates a powerful laser beam by using a stack of diodes to produce the laser power. The laser’s ability to be precise and consistent results from the beam getting concentrated utilizing a fiber optic cable. This machine uses computer numerical control (CNC) to improve the cutting accuracy and ensure the laser beam moves in the correct direction.
CNC CO2 Laser
This laser machine uses carbon dioxide as the active laser medium in their machine. CNC technology often uses them, improving the lasers’ accuracy and precision. Given its high power output and excellent efficiency, this laser gets heavily utilized in the industry. This machine is ideal for cutting thin sheet metal or anything else with a thickness of fewer than 10 millimeters.
CNC Crystal Laser
In a CNC crystal laser, the high-powered output gets generated by the beams that come from the crystal. Neodymium-doped yttrium aluminum garnet and neodymium-doped yttrium ortho-vanadate are examples of the materials used in constructing these machines. These machines use CNC technology, guaranteeing the precision and the shape produced. Therefore, crystal lasers have a higher intensity than other forms of lasers. They can also cut through various materials, including carbon steel, aluminum, and thin metal sheets.
Difference Between the CNC Cutting & Laser Cutting
Both are different from one another due to the presence of certain features that set them apart. The primary distinction is in the way in which they operate. The term “friction” refers to the interaction of the tool being used to cut the material, and it is the driving force behind the CNC cutting process.
On the other hand, the procedure used for laser cutting is the opposite. When laser cutting, the equipment directs intense laser beams onto the substance. Compared to CNC laser cutting, laser cutting takes place without the machine ever coming into contact with the material.
The pricing is also another point of differentiation between them. Because of the higher level of technology, a CNC machine will be 10% more costly than a laser cutting machine. Due to this, if you run a small creative company and need a wide variety of cutting tools, you should consider investing in a CNC machine. Laser cutting is the method of choice for industrial applications since it simply requires a predetermined set of forms, and there is a high demand for production.
CNC Laser Cutting Machine Applications
CNC laser machines offer various applications in manufacturing, including engraving, large-scale cutting production, 3D printing, medical usage, and the textile industry. These machines get utilized in multiple industries because of their highly efficient process and technology. In addition, since CNC technology has been accessible, many businesses are deciding to use such cutters. The following are some of the most prevalent uses for laser cutting that are currently available:

Engraving
Due to the high precision and accuracy required in engraving and marking, most companies use such lasers. In this application, computer numerical control (CNC) technology uses features to specify the material’s engraving or marking. With the assistance of these CNC laser cutting equipment, you can operate on even the tiniest thing possible.
3D Printing
Printing objects with 3D technology is the construction method of the future. The development of 3D printers and the rising demand for them have led to the use of CNC laser cutting machines in producing these devices. Devices known as 3D printers are those that are modified to make use of laser technology. You can cut through various materials and patterns with CNC laser cutting integrated into the printing machine.
Workshop
As a result of their versatility and ability to operate with a wide variety of equipment, these machines are also an ideal choice for small workshops. Due to this, there is a significant and growing demand for CNC lasers in workshops. They cut various materials and objects into multiple forms and dimensions.
