Main Maintenance & Treatment Methods For CNC Hydraulic Press Brake

CNC hydraulic press brake without work progress

1. PV valve, check signal or clean
2. If single-side no progress, may be filling valve, remove and clean
3. Check the signal of intermediate relay

CNC hydraulic press bending force is not enough, high oil temperature

1. Check whether the oil is dirty
2. The filter needs to be replaced
3. The pump is damaged
4. The proportional pressure valve dirty, need to clear
5. The main valve loosen, need re-lock

CNC hydraulic press Ram running vibrantly

1. Check the slider rail elastic
2. Adjust the machine parameters

CNC hydraulic press brake bending angle or size is not accurate

1. Both sides of the angle can be amended on the system
2. Check whether the slider connection is loose
3. Check the workpiece material, material is uniform
4. Check whether the mold has been worn
5. Size is not right, first check the parallelism of backgauge, then check the stoppers
