Function introduction:
The machine tool?is mainly used for?piston pinhole semi-finishing, circlip groove finishing and chamfering inside and outside of pinhole.
SIEMENS 828D(with double-channel) ?system?is adopted, and the Z1/Z2 axes are?adopted with?the AC servo motor driver. The left and right radial servo system is that the rotary oil cylinder with controllable stroke(or X1, X2 axis?of Servo motor) drives the left and right boring heads to make boring rod have radial offset, so the piston pinhole semi-finishing, circlip groove finishing and chamfering inside and outside of pinhole can be completed.
