M677 - Duplex worm milling machine

All modules units are built on a solid base of cast iron. The linear guides for the headstock and the tailstock are mounted on the same base.

M677

The longitudinal and plunge axis are driven by precision ball screws.

The direct drive workpiece spindles (synchronous motors) can be equipped with W20 or W25 collets, with a mandrel retraction system or a cusomized work holding system. Pneumatic system for collet and mandrel retraction system.

The CNC-tailstock clamping pressure can raise up to 2500 N, torque controlled. Below 500 N, the clamping pressure is generated by spring load.

The swivel angle on the milling spindle is manually adjustable within a range of ± 30 ° and is displayed on-screen. Optional CNC controlled.
