Machine description
Technical details

The MATECH CNC piston lathe is designed for turning oval or complex-shaped piston skirts.
The oval machining unit's axis is an autonomous, highly dynamic positioning system.
Thanks to a highly efficient real-time control core and extremely short controller sampling times, extremely fast and precise positioning operations can be performed using the actuator.
The hydraulic tailstock ensures the high stop rigidity required for machining the piston skirt.
