First check the three-phase power supply is normal, whether the lack of phase, and then check the fuse box device is intact, then check the corresponding printed circuit board fuse is intact.
1. After the CNC EDM electromechanical box is opened, no display is displayed.
Check if the monitor display card inside the computer is loose or replace the display card.
2. The CNC EDM puncher failed to start the computer.
According to the display of the display to determine the corresponding action, generally should be poor contact between the motherboard and the slot or memory board on the motherboard.
3, CNC electric spark piercing machine computer crashes or computer internal alarm.
The CPU fan on the main board is stopped or the air inlet of the computer casing is contaminated. Replace the CPU fan and clean the air inlet grille.
4. When the CNC electric spark piercing machine is processing, the voltmeter has no voltage:
1 Check whether the KM4 is closed 2 Check the power rectifier bridge and related devices 3 Check the power circuit board or replace 5. The CNC electric spark piercing machine does not feed or return.
Check the status of the servo control board or replace it.
6, CNC electric spark piercing machine discharge that produces a strong spark.
The VMOS tube on the power supply PCB is damaged or the control has failed. Replace the power supply PCB.
7, CNC EDM machine without working fluid. Pump motor does not turn:
1Check whether the thermal relay FR has actuated 2 Whether the working fluid pump is blocked or the motor is lack of phase 3 The filter is clogged and the working fluid is not enough
