ETK2406 NC Combined Boring Machine for Piston Pinhole
Views:122 Date:2021-10-08 

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.
