125MN挤压机主剪缸深孔加工

Deep hole machining of main shear cylinder for 125MN extruder

125MN卧式挤压机中主剪油缸采用倒装活塞缸驱动结构,外形为异型件,深孔加工装夹和找正困难,通过采用工艺创新,制作专用工装支撑套,保证了深孔的加工和精度。

The main shearing cylinder of 125MN horizontal extruder adopts the driving structure of inverted piston cylinder. The shape of the cylinder is abnormal. It is difficult to install and correct the deep hole processing, By adopting the innovative technology and making the special tooling support sleeve, the machin- ing and precision of the deep hole have been guaranteed.
