6 Reason Why The Fiber Laser Cutting Machine Cannot Cut Through Metal

With the increasing popularity of laser cutting machines in the processing industry, many processing problems have become apparent.

The problem of not cut through during the fiber laser cutting is relatively difficult.

Then why does this kind of problem occur in the equipment? Let me briefly introduce some reasons.

The power of the laser decreases

After using the laser of the fiber laser cutting machine for a long time, the power will gradually decrease with the use of time, and eventually the cutting capacity will decrease, and the case of not cut through will also occur.

The thickness of the processed plate exceeds the cutting limit

Laser machining

There is a limit cutting thickness for fiber laser cutting machines with different powers.

If the limit thickness is exceeded, the cutting effect of the equipment will be unsatisfactory, including the case of not cut through.

Optical component pollution

Optical elements include focusing mirrors, reflect mirrors, etc. Because it is in a poor working environment for a long time, it is easy to cause residues on the surface of such lenses, which reduces the laser power of the equipment and leads to not cut through problem.

The light spot debugging of the equipment is not up to standard

The spot of the fiber laser cutting machine is one of the most important factors that affect the cutting quality. When the spot debugging fails to meet the standard, the not cut through problem may also occur.

The cutting speed of the laser cutting machine is too fast

If the cutting speed is too fast, missed cuts will inevitably occur, which will cause not cut through problem.

The auxiliary gas pressure of the equipment is not enough

The auxiliary gas is used to help blow off the residue during cutting. When the air pressure is not reached, the residue is difficult to remove, which will cause the cutting to be not cut through.

The above six points are the main reasons why the fiber laser cutting machine cannot cut through. The majority of users can pay more attention to these problems during daily use. When faced with a problem, it needs to be solved step by step, so as to obtain better results in daily processing.
