The machine is mounted on a solid cast iron base, inclined to the front side by 15°.

The longitudinal-, the shift- and the plunge axis are driven by a ball screw.

The work piece spindle can be equipped with W25 collets, retractable arbors or customer specific work holding.

The CNC-tailstock clamping pressure can reach up to 3000 N, torque controlled. Below 500 N, the clamping pressure is generated by spring load.

The CNC-shift axis is integrated in the hob head and has a travel distance of 60 mm. The Hobbing- and milling spindle is equipped with ball bearings. Tool holders are fit to a cylindrical bore. The swivel angle on the hobbing- and milling spindle is programmable. The range go’s from +45° to 0° to -127°.

The spindle drive is a motor spindle.
