Causes of sawtooth in the processed section of fiber laser cutting machine


The popularity of fiber laser cutting machines in the current sheet metal processing industry is very high. It has good cutting effects and neat processing sections. It is deeply loved by the sheet metal processing industry. The popularity of fiber laser cutting machines is also inseparable from the improvement of the manufacturing technology level of the majority of manufacturers.

Good equipment manufacturing technology and high-end brand accessories are the guarantee of the quality of the laser cutting machine. There will be various problems in the daily processing and production, such as sawtooth on the processing section, so why does this happen?


Machine parallelism

If the parallelism of the laser cutting machine is not installed properly, the equipment will be unstable during processing, resulting in jitter, and the processed material section will have sawtooth.


Equipment vibration

Fiber laser cutting machine vibration has two situations. One is the vibration of the equipment itself during cutting, which will affect the cutting effect, and the other is the problem of external equipment, such as exhaust fans and water tanks that are placed too close to make the equipment vibrate.


Gear related aspects

When the gear seat slips, it will also cause sawtooth on the processing section.Rails are not installed parallel

Sometimes the Y-direction guide rails are not installed in parallel, and there will be jams during equipment processing. Such cutting sections may also appear jagged.


The lens is not fixed

When the lens is not fixed, the lens shakes when the equipment is running, the beam will also vibrate, and the final cut section will also appear jagged.


Equipment slider wear

When the fiber laser cutting machine is used for a long time, some sliders will be worn out, and there are some foreign objects in the internal balls, which will cause the guide rail to jitter during operation, so there will be jagged problems after processing.


When we have a sawtooth problem when we cut the fiber laser cutting machine, we can hold the laser head by hand to prevent it from jittering. If there is no sawtooth problem after holding it by hand, it must be a slider problem; If it still appears, then you have to check the belt, gear and other accessories. If this kind of problem occurs in the new machining, it should be considered whether it was not installed properly during installation, or its control drive and motor are not matched.
