During the woodworking engraving process, you may encounter the following problems with the spindle motor:
(1) The pressure and stroke of the loose knife hydraulic cylinder are not enough.
(2) The disc spring is too tightly pressed so that the spindle clamp cannot move completely to the correct position and the tool cannot be loosened.
Corresponding solutions:
(1) Exclude by adjusting the hydraulic pressure and the position of the stroke switch.
(2) By adjusting the nut on the disc spring, reduce the amount of spring press to eliminate.
