The jig of the CNC machine tool mainly has the hydraulic power chuck and tailstock which is used for the disk type, the shaft type part processing.
1. Hydraulic Power Chuck
The clamping force can be controlled by adjusting the pressure of the hydraulic system, which has the characteristics of compact structure, sensitive movement and the ability to achieve large clamping force.
For the processing of long shaft parts and drilling, reaming and so on, CNC machine tools generally have manual tailstock and programmable tailstock two kinds, tailstock sleeve action and the main axis interlock, that is, in the spindle rotation, according to the Tailstock sleeve exit button, the sleeve does not move. Only when the spindle is stopped can the tailstock sleeve exit to ensure safety.
