What is the reason for the vibration of the laser cutting machine when moving back and forth?
Below is a brief introduction to the reasons for the occurrence:
1. There are obstacles or loose tension wheels on the machine.
2. The polarity setting of the motherboard parameter reset detection is incorrect.
3. Clamp the Timing belt, slick head, blower pipe and drag chain.
4. If there is too much dust on the guide rail, it is necessary to remove the dust and add lubricating oil to the slider.
5. The slider clearance is too large and needs to be replaced.
6. The beam is severely offset and the supporting wheels on both sides are damaged.
7. Poor contact between the motor and the drive link wire.
8. The motor or driver has malfunctioned.
9. The motherboard has malfunctioned.
2. What are the common faults and handling methods of laser cutting machines?
One is that there is no program to start normally:
Fault manifestation: The cutting blade of the cutting machine shakes left and right.
The main power switch indicator light is not on, the motherboard indicator light is not on, the panel is not displayed, the motor drive indicator light is not on, and the machine is buzzing.
Fault cause:
Solution | Poor contact of the main power supply, damage to the DC power supply, control panel failure, motor drive failure, mechanical failure. Operators can solve it step by step.
Specific inspection methods:
1. Observe the indicator light on the machine, observe the fault location, the main power switch indicator light is not on, check whether the input power supply has poor contact or the power fuse is burnt out, check the motherboard LED, and ensure that the DC 5V and 3.3V power output is normal, and the motor drive indicator light is not on,? Check if the power output is normal, pay attention to checking if the power supply is normal, disconnect any power output wires for testing to determine the fault of the power supply or power supply components.
2. Check if all displays are functioning properly. If you can hear a noticeable buzzing sound, it must be a mechanical malfunction.
3. The guide rail is smooth and there are no obstacles. See if there’s anything else blocking it. Check if the motor shaft is separated and if the synchronous wheel is loose,
4. Check if the motherboard, power supply, and wires or plugs connected to the driver block (device) are in good contact.
5. Check if the wire connector from the drive block (actuator) to the motor is disconnected. The 18 core wire from the motherboard to the small board is damaged. Is there any insertion phenomenon.
6. Check if the parameter settings are correct. The parameters on the left are the same. Different ones should be corrected and written into the machine.
2、 The panel has no display and the button cannot be activated: the cutting machine is shaking when cutting.
Fault symptom:
The most likely issue is that the power on panel is not displayed, the buttons are malfunctioning, or there is no action.
Fault cause:
The power supply of the display control block is abnormal, the control connection is poor, and the panel is faulty.
Specific inspection methods:
1. Check if the crossbeam and car reset are normal, no action, no action fault handling. What’s the matter with the cutting machine shaking left and right.
2. Press the start reset button, press the direction and function keys on the machine panel, and check if they are normal, if the button can automatically reset, and if there is any deviation.
3. Check whether the connection display control, socket, and connector are loose and free of contact.
4. Replace the display control block, check if the indicator light on the control block is on, and if there is no power supply,
5. Replace the data cable.
