Corvus C-Type

Corvus_CType

CORVUS cType, grinding with higher performance for numerous applications. The machine bed made from the latest generation of polymer concrete provides tremendous stability, is resistant against thermal expansion and allows high acceleration and high speeds for all axes.

 

The grinding head consists of a high-performance electric spindle (up to 50 kW peak) with internal cooling. The powerful cooler also contributes to thermal stability, especially if the material is highly abrasive.

 

Typical applications:

• Profiling racks, straight or angular toothing

• Grinding grooved shafts with any type of profile

• Grinding compressor screws and gear worms

• Regrinding large hob cutters, e.g. for the wind power industry
