What is a laser cutting machine?

The working principle of laser cutting is to use high-power and high-density focused laser beam to cut industrial products so that the irradiated materials can quickly melt, vaporize, ablate or reach the ignition point, and then become the shape users want. In this paper, the principle, components, and classification of laser cutting machines will be introduced in detail.

Here is the content list:

·Working principle



Working principle

Laser is a kind of light, like other conventional light, is generated by the transition of atoms. But different from ordinary light, laser only depends on spontaneous emission for a very short period in the beginning, and then the process is completely determined by stimulated emission. Therefore, the laser has a very homogeneous color, almost no divergent directivity, extremely high luminous intensity, and high coherence. Laser cutting is implemented by using high power that density energy produced to achieve that goal which is laser focusing. The pulse laser beam is radiated and reflected by the optical path, and focused on the surface of the processing object of the focusing mirror group, forming a fine, high-energy-density spot.

The focal spot is located near the surface to be processed, Melt or vaporize the processed material at instantaneous high temperature. Each high-energy laser pulse instantly splashes a small hole on the surface of the object. Under the control of the computer, the laser processing head and the material to be processed continuously move relative to each other according to the pre-drawn figure. In this way, the object will be processed into the desired shape.

The process parameters (cutting speed, laser power, gas pressure, etc.) and motion trajectory are regulated by the numerical control system, and the slag at the cutting seam is knocked out by the auxiliary gas with a specified pressure.


Laser cutting machine system generally consists of laser generator, beam transmission module, worktable (machine tool), computer numerical control cabinet, cooler, and computer (hardware and software).

The laser cutting machine is composed of operation software such as frame, light path system, circuit, working platform, and water channel. There are six parts in the light path: light source, light source conduction system (lens), mechanical transmission system, electronic circuit, control software, auxiliary equipment (exhaust system, cold water system, air blowing system, etc.)


Laser cutting can be divided into laser vaporization cutting, laser melting cutting, laser oxygen cutting, and laser scribing, and programmed fracture.

The above is the introduction of a laser cutting machine. A laser cutting machine is a kind of automated typesetting machine equipment, it can save a lot of materials, and the material cut by the laser cutting machine is very flat, the incision is very smooth.

The price of metal laser cutting machines is not cheap, the general price is more than 10000 or 20000, but this kind of equipment can reduce the processing cost in the operation. Most processing manufacturers will choose this kind of equipment, which can reduce the manufacturing cost and processing cost of enterprises.

The above is the whole content of the laser cutting machine. The laser cutting machine is popular because of its high efficiency and convenience. It is widely used on many occasions. It can bring many benefits to our work if we give full play to its advantages reasonably.
