How to judge the processing quality of laser cutting equipment?

When people buy , they generally laser cutting equipment  pay more attention to its processing quality,  want to buy a laser cutting equipment with good processing quality . So how do you judge the processing quality of laser cutting equipment? The following editor will tell you the standard for judging the processing quality of laser cutting equipment when you buy it.

There are many laser cutting equipment manufacturers on the market,  the laser cutting equipment produced is also different,  the shape to the equipment, are very different. If you want to buy a good laser cutting equipment, how should we choose it? The quality of the cut products is a way to check the laser equipment. Below, Wuxi Rewards introduces you to the laser with years of experience in the production of laser cutting equipment Judgment standard of cutting equipment processing quality.

Regarding the processing of the majority of laser cutting machines , commenting on the quality of their processing mainly includes the following points:

1. Lubrication at the laser cut surface, less texture, no brittle fracture When the laser cuts the plate at high temperature, the trace of the molten material will  appear in the cut under the straight laser beam, but will be sprayed out behind the laser beam. As a result, the tortuous texture is formed at the cutting edge,  the texture closely follows the moving laser beam. In order to modify this problem, the feed rate is reduced at the end of the cutting process, which can greatly reduce the texture of the line;

2. The width of the slit is narrow (this is mainly related to the size of the laser beam spot diameter, which depends on the quality of the laser tube) The width of the slit does  generally affect the quality of the incision. When the fine summary is formed in the part, the width of the incision has an important impact This is because the cut width determines the small internal warp that is summarized. When the thickness of the plate is added, the cut width is also added. Therefore, if you want the same high precision, no matter how large the cutting width is, the workpiece should be stable in the processing area of the laser cutting equipment;

3. The straightness of the slit is good,  the heat affected area is small. When the thickness of the processed material exceeds 18mm, the straightness of the cut margin is very important; when away  the focal point, the laser beam becomes divergent. It widens towards the top  bottom. The cut margin violates the pen straight line by a few millimeters, the straighter the margin, the higher the cut quality;

4. Thermal influence of cut material As a thermal cutting processing application equipment, it will form a thermal influence on the material during the application process. Its embodiment mainly includes three aspects: a. heat affected area; b. depression  corrosion; c. material The heat-affected area during deformation means that the area adjacent to the cut is heated during laser cutting. Together, the structure of the material itself changes. For example, some materials will harden.

The heat-affected zone refers to the regional change in the internal structure that changes due to high temperature;  the depression  corrosion have an adverse effect on the appearance of the cut margin  affect the appearance. They appear in cut errors that should normally be avoided; then if the cut overheats the part, it will deform.

This is very important in finishing, because the generalizations  connecting pieces here are generally only a few tenths of a millimeter wide. Manipulating laser power  using short laser pulses can reduce component heating  prevent deformation.

It can be seen that it is  easy for a qualified laser cutting equipment to pass the test. Here, the buyer is reminded to carefully study the characteristics of the processed material before purchasing the equipment, adjust the parameters for cutting,  investigate the sample after the cutting is completed. quality.

The above four aspects can be achieved as a qualified laser cutting equipment. The detailed appraisal in the early stage saves a lot of trouble for the later processing. The purchaser should  a large laser equipment manufacturer to purchase the equipment,  have after-sales guarantee  processing training.

Generally, after reaching the above standards, the processing quality of laser cutting equipment is qualified,  you can also buy laser cutting equipment with confidence.
