1: The precision of the engraving machine is not enough.
The bed structure is not reasonable enough and the rigidity is not enough.
The original parts processing accuracy is not up to standard.
The assembly is not up to standard and has not been tested by special measuring tools.
The motor power is not enough, resulting in lost step
The spindle has insufficient torque and is not smooth enough to cut out.
Unreasonable parameter setting, pulse equivalent, servo gain, etc.
The workpiece is not fixed enough
Reducer damage
Gear box screw loose
2: The machine cannot return to zero
The home switch is faulty.
The track and rack are not installed properly, and there is a card phenomenon.
Motor degaussing leads to lost step
Is the control card and NC controller damaged?
Is the switching power supply damaged?
3: Power on trip
Line ground short
Electric cabinet leakage circuit
Air pressure switch and leakage protector failure
4: Driver and inverter alarm
Frequency conversion and drive power are too small, can not move
Line disconnection and short circuit
The parameter setting is incorrect, and the voltage parameter is incorrectly adjusted.
Processing file error
Brake is not open
5: Spindle heating
The line is too thin to withstand too much load
The water cooling configuration of the main shaft is unreasonable. The water pipe is too small and the head is not enough. It is best to equip the water cooler.
The power is too small to move
6: Functional processing is not smooth and misplaced
Clamping is not strong enough
The spindle has insufficient torque
Motor quality is not good enough
The document drawings are not perfect enough
Unreasonable tool selection
Feed rate, spindle speed and machining speed are unreasonable
Adjust the parallelism of the machine, check the slider, motor belt, coupling, loose and damaged
Adjust the three-point concentricity tightness of the motor seat of each shaft bearing housing
Is there static electricity or external interference, is there a ground wire?
7: Equipment failure can not be repaired
Without professional simple maintenance and lack of common sense, you should choose quality suppliers for training.
Purchase of spare parts for replacement (bearings, limit switches, leakage protectors, etc.)
