Before the design is given several options for comparison and demonstration and choose the optimal program design. The hydraulic system design is based on the clamping chuck lathe with loosen, chuck clamping force.on the throats of high and low voltage conversion and rotation of change knife . Analysis of the hydraulic system of the necessary parameters of strict scientific computing. Through the analysis of the results, we have selected and then select the hydraulic circuit and hydraulic system diagram is given. In determining the hydraulic system diagram, according to the work pressure of hydraulic system and components through various valves and auxiliary components of the actual flow of the hydraulic components were selected. When the hydraulic system of the main determined, on the hydraulic manifold block also carried out stations and simple design. Through the CNC lathe hydraulic system chuck and rotation of change knife design change，Make existing machine in original basis be more big improvement , Make processing production steps more simple, thus reduce the labor intensity, improve efficiency, saving energy.
