The laser power will affect the speed of the laser cutting machine. The cutting speed will affect the cutting quality. Under certain laser power conditions, too fast or too slow will affect the surface flatness of cutting materials.
How to select the cutting speed of the laser cutting machine?
If the cutting speed is too fast:
1. The laser beam and material contact each other in a short time, which may lead to failure to cut.
2. Some areas can be cut, but some areas cannot be cut.
3. The whole cutting part is layered.
4. The printing plate cannot be cut off in time. The cut surface shows a diagonal stripe road, and the lower part will produce molten stains.
If the cutting speed is too slow:
1. The interaction time between the material and the laser is too long, resulting in excessive melting of the plate and rough cutting.
2. The gap becomes wider. It will cause excessive combustion on small rounded corners or sharp corners, and can not obtain ideal cutting effect.
3. The cutting efficiency is low, affecting the production capacity. Judgment method of cutting speed.
How to determine the appropriate cutting speed?
1. The cutting speed is reasonable: sparks are scattered from top to bottom, the cutting surface is smooth, and the lower part is free of slag;
2. Cutting speed is too fast: the cutting spark is inclined;
3. Cutting speed is too slow: cutting sparks gather together and do not spread.
