During the use of laser cutting machine, due to the influence of materials, processes, environmental conditions and human factors, the technical state of the equipment will be degraded, and various faults will inevitably occur, and the function and accuracy of the equipment will be reduced. The whole machine loses its value in use. Knowing the mastery of some common faults and solutions, keeping the on-site laser cutting machine in a good state, improving the utilization rate and prolonging the service life are the needs of enterprises to improve economic efficiency.
1, boot without any reflection
Whether the power fuse is burnt out: replace the fuse.
Is the power input normal: Check the power input and make it normal.
Is the main power switch damaged: Replace the main power switch.
2, no laser output or laser is weak
Whether the optical path is offset: carefully adjust the optical path.
Whether the reflective lens is contaminated or damaged: clean or replace the reflective lens.
Whether the focus of the laser cutting machine changes focus: readjust the focus.
Concentration of the focusing mirror: Clean the focusing mirror.
Whether the cooling water quality or water temperature is normal: replace the clean cooling water to bring the temperature to a normal value.
Whether the cooling water circulates: clear the cooling waterway.
Whether the laser tube is damaged or aged: Replace the laser tube.
Whether the laser power is on: Check the laser power supply circuit to make it normal.
Whether the temperature of the whole machine is too high: 1. Shut down to lower the temperature; 2. Ventilate to strengthen the heat of the machine; 3. Adjust the ambient temperature.
Is the laser power supply damaged: Replace the laser power supply.
3, cutting / engraving depth is not ideal
Whether the cutting/engraving processing parameters are normal: Set the appropriate processing parameters.
Is the laser power setting normal: Set the laser power correctly.
Laser output is weak: see point 2.
4, the computer and equipment are not online
Whether the scan switch is on: Turn on the scan switch.
Is the motion system energized: Check that the motion system is powered and normal.
Is the DSP motion control card damaged: Replace the DSP motion control card.
Is the signal cable loose: Re-plug the signal cable and secure it.
5, the processing size has errors or malfunctions
Is the whole machine and computer grounded properly: Ground the device and computer well.
Is the signal line normal: Replace the signal line.
Computer operating system failure or virus infection: Reinstall the operating system or antivirus.
Is the computer running properly: replace or dispose of the computer.
The power supply is unstable or has an interference signal: install a voltage regulator or eliminate interference signals.
Whether the application software is normal: Reinstall the driver software for the software and motion control card.
Whether the processing parameters are set correctly (such as layout, etc.): reset the corresponding parameters
Whether the machining program is written normally: Check the programmed machining program and modify it until it is normal.
6, the slider movement is not ideal
Whether the trolley slides and sliders are contaminated: clean the slides and sliders.
Whether the rails are contaminated: Clean the rails and add lubricant.
Is the transmission gear loose: tighten the transmission gear
Is the drive belt loose: Adjust the belt tightness.
