What are the criteria for judging the cutting quality of laser cutting machines?

Date: Sep. 13, 2021

With the development of science and technology, laser technology has been applied to all walks of life. As a precise processing method, laser cutting can cut almost all materials, including two-dimensional cutting or three-dimensional cutting of thin metal plates. Laser cutting machine is a technological revolution in sheet metal processing and the "processing center" in sheet metal processing.

The laser uses material excitation to generate light. This light has a strong temperature. When it comes into contact with the material, it can quickly melt on the surface of the material to form punching holes. Compared with the traditional cutting method, the cutting method has smaller gap and faster cutting speed.

The cutting quality and effect of the laser cutting machine are very good, but there are many factors that will affect the cutting quality of the laser cutting machine. So, what are the factors that affect the cutting quality of the laser cutting machine? The technical engineers of Lixing Laser will analyze and answer for you.


Judging cutting quality of laser cutting machines What are the standards?


Analysis of factors affecting the cutting quality of laser cutting machine:

1. The cutting width and verticality that affect the cutting quality of the laser cutting machine

The width of the cut usually does not affect the quality of the cut. The width of the cut only matters when a particularly precise contour is formed inside the part. This is because the width of the cut determines the contour. As the thickness of the sheet increases, the width of the cut also increased. If the thickness of the metal plate exceeds 10mm, the verticality of the cutting edge is very important. As you move away from the focal point, the laser beam becomes divergent, the cut widens towards the top or bottom depending on the position of the focal point, and the more vertical the edge, the higher the quality of the cut.

2. Roughness and texture that affect the cutting quality of laser cutting machine

The laser cut part will form a vertical texture, and the depth of the particle determines the roughness of the cut surface; the shallower the particle, the smoother the cut part. In most cases, roughness must be reduced as much as possible, so the lighter the texture, the higher the quality of the cut. When cutting a slab at high speed, the molten metal does not appear in the slit under the vertical laser beam, but is ejected after the laser beam is deflected, resulting in a curved line at the cutting edge, and the line closely follows the moving laser beam, To solve this problem, the feed rate was reduced at the end of the cutting process.

3. Material deposition, burr and deformation that affect the cutting quality of the laser cutting machine

During the cutting process, the surface of the slit can form a deposit on the surface, and the amount of deposited material can also be seen in the quality of the laser cutting equipment. The formation of burrs determines a very important factor in the quality of laser cutting, because removing the burrs requires extra work, so the severity and quantity of the burrs can directly determine the quality of the cutting. If the cut causes the part to heat up sharply, deformation will occur, so the less deformation, the better the cut quality.

The above is an analysis of the factors that affect the cutting quality of laser cutting machines.
