The laser cutting machine is welcomed by all walks of life because of its advantages such as high cutting speed, narrow cutting seam, high cutting quality, small Heat-affected zone and wide application range. The laser cutting process may be affected by various factors, so many problems may arise during the cutting process of the laser cutting machine. Let’s take a look together!
- Laser cutting cannot cut through thoroughly
Laser power decrease or lamp tube aging
Laser cutting speed too fast
The focusing mirror or reflector is contaminated
Cracking of the focusing mirror and deterioration of the focusing effect
Inappropriate focus adjustment
Incorrect laser path
Voltage instability and low laser current
The cut material has a high reflectivity
The nozzle light outlet is blocked
Auxiliary gas pressure too low
Poor cooling system heat dissipation effect 6
- The starting point and key point of the cutting closed line do not coincide
Looseness between gears and shafts in the workbench
The X-axis and Y-axis guide rails are not perpendicular
X. The conveyor belt of the Y-axis is loose
Excessive gap between slider and guide rail
The tape is too loose, resulting in reverse clearance
- The laser head does not produce a light source
Laser power decrease or lamp tube aging
Laser output energy too low
Loose screws inside the laser cutting head cause optical path deflection
There is a lot of dust in the laser cavity, which contaminates the diaphragm frame
The cooling system is turned on for a long time without turning on the laser power, resulting in icing and no light output
- There is a large deviation in the cutting shape of geometric shapes (circular shapes are cut into ellipses, square shapes are cut into parallelograms)
The parameter settings of the machine tool are not accurate
X. Y-axis guide rail not perpendicular
- The workbench jumps during the cutting process
Permanent deformation of the drive belt
Dirt and incorrect meshing in the transmission gear groove
There is dirt in the grooves of the small and large reduction gears
- Cutting size is too large
Incorrect pulse count setting
The radius compensation is not set
Incorrect factory parameter settings for the bed
- Severe edge melting on the cutting surface
Excessive laser output power
Laser cutting speed too slow
Auxiliary air pressure is too low
Unreasonable nozzle design
- An alarm occurs during cutting
The software is not working and the host is loose
Failure to turn on the cooling system resulted in excessively high temperature in the laser cavity
The water pressure in the cooling system is too low, and the water level is not enough
- The laser power cannot be turned on
Emergency stop switch closed
Damaged laser power supply
