1. Long-term overpressure use. It will also cause insufficient pressure on the cutting machine.
2. Long-term use of small knife molds on large workbenches, and use off-center positions.
3. The knife mold is used for a long time in front and back or left and right, and used in a fixed position for a long time.
4. The oil pump is the power of the cutting machine. If the oil pump is damaged or oil leaks, the pressure of the hydraulic cutting machine will be insufficient.
The above reasons will cause uneven pressure on the cutting machine, I hope it can help you.
