Accessories / Special Features
* BWO (HECKLER & KOCH) CNC Control model 785 H for altogether 7 axes. Input via monitor. The control has all the supervision and fault diagnosis features necessary for fully automatic working process.
* 2 workspindle units, left and right, which can be set at any angle.
* CNC controlled: Z and W Axes for tool cross slide. X and U Axes for tool longitudinal slide.
* L and O Axes for milling spindle. C Axis for workspindle rotation.
* Manually controlled: Tool slide rotary table (B and E Axes). Tool slide vertical infeed (V and Y Axes). Tilt of tool head (A and D Axes). All axes have digital display in the control.
* Hydraulically operated workpiece clamping device in conjunction with an automatic loading device using workpiece feed / conveyor belt and swivelling loading device, as well workpiece control by air.
* Coolant equipment with chip conveyor. * Noise protection cabin. * Central lubrication.
* Built-on hydraulic unit. * Pneumatically driven safety doors. * Deburring device, etc.

The machine uses the hypocycloidal milling principal, with electronically synchronized tool and workpiece axes for working straight roof-formed teeth, symmetric as well as asymmetric forms. Advantages are high precision and productivity.
