M667 - Worm milling machine

All modules units are built on a solid base of cast iron and mounted on a 10 ° inclined to the rear machine base.

M667

Headstock and tailstock are mounted on the same slider base.

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

The workpiece spindle can be equipped with W20 collets, with a mandrel retraction system or customized clamping systems.

Collets and mandrel retraction system are actuated pneumatically.

The CNC-tailstock clamping pressure can reach up to 350 N, torque controlled. Below 50 N, the clamping pressure is generated by spring load.

The swivel angle on the milling spindle is manually adjustable within a range of ± 35 ° and is displayed on-screen.

The spindle drive is over a precision worm gear.
