Fiber laser cutting machine may have various faults during use, affecting production efficiency and processing quality. The following are some common faults and their solutions:
1. Laser related faults
Laser has no laser output
Possible reasons:
Power failure
Laser internal components damaged
Water cooling system failure leads to laser overheat protection
Control signal abnormality
Solution:
Check whether the power connection is normal and whether the power switch is turned on
Contact the manufacturer or professional maintenance personnel to check the internal components of the laser
Check whether the water cooling system is working properly, whether the water pressure and water temperature are normal
Check whether the control signal line is connected normally and whether the control software is set correctly
Laser power drops
Possible reasons:
Laser aging
Focus lens is contaminated or damaged
Laser transmission fiber is damaged
Cooling water temperature is too high
Solution:
Contact the manufacturer or professional maintenance personnel to detect the laser power, replace the laser if necessary
Clean or replace the focusing lens
Check whether the laser transmission fiber is damaged, replace the fiber if necessary
Check the cooling water temperature to ensure that it is within the normal range
2. Faults related to the motion system
Abnormal movement of the cutting head
Possible causes:
Motor driver failure
Motor failure
Guide rail or lead screw wear
Limit switch failure
Solution:
Check whether the motor driver is working properly, and replace the driver if necessary
Check whether the motor is working properly, and replace the motor if necessary
Check whether the guide rail or lead screw is worn, and replace it if necessary
Check whether the limit switch is working properly, and replace the limit switch if necessary
Decrease in cutting accuracy
Possible causes:
Loose mechanical structure
Improper servo motor parameter setting
Focus position of cutting head Offset
Solution:
Check if the connection of each component of the mechanical structure is loose, and tighten it if necessary
Re-adjust the servo motor parameters
Recalibrate the focus position of the cutting head
III. Auxiliary system related faults
Abnormal gas pressure
Possible reasons:
Insufficient gas source pressure
Gas pipeline is blocked or leaking
Gas pressure regulating valve failure
Solution:
Check if the gas source pressure is normal
Check if the gas pipeline is blocked or leaking, and replace the gas pipeline if necessary
Check if the gas pressure regulating valve is working properly, and replace the gas pressure regulating valve if necessary
Water cooling system failure
Possible reasons:
Water pump failure
Water pipeline is blocked or leaking
Water tank water level is too low
Solution:
Check if the water pump is working properly, and replace the water pump if necessary
Check if the water pipeline is blocked or leaking, and replace it if necessary Replace water pipe
Check the water level in the water tank and replenish cooling water in time
IV. Software-related failures
The software cannot be started
Possible reasons:
Incomplete software installation
Incompatible system environment
Corrupted software files
Solution:
Reinstall the software
Check whether the system environment meets the software operation requirements
Contact the software supplier for technical support
Abnormal software control
Possible reasons:
Wrong software parameter setting
Control card failure
Signal interference
Solution:
Check whether the software parameter settings are correct
Check whether the control card is working properly and replace the control card if necessary
Check whether the signal line connection is normal and take anti-interference measures if necessary
It should be noted that the above are only some common faults and their solutions. Other problems may be encountered in actual operation.
In order to reduce the occurrence of faults, it is recommended that users:
Regularly maintain the equipment
Use the equipment strictly in accordance with the operating procedures
Contact the manufacturer or professional maintenance personnel in time to solve the fault problem
