CoroMill® 178

PM-HSS and solid carbide power skiving tools for gear and spline production with high output

High productivity and flexibility

​Possible to machine the complete component in universal 5-axis machine in one single set-up.

Reduced cycle times

​Considerably reduced machining cycle time compared to conventional machining methods, such as broaching, shaping and hobbing.

Efficient also in dry machining

​Power skiving runs efficiently also in dry conditions, which eliminates coolant costs and makes for environmental- and operator-friendly machining.

Chamfering and deburring tools to complement the power skiving tools are also available.


What is power skiving?

 

Power skiving is a continuous cutting process that enables all machining to be carried out in a single setup. In essence it is a combination of hobbing and shaping. The intersecting angle between tool and gear axes is decisive for productivity – the larger the angle, the better the productivity.  

A further advantage of the machining method is its capability to machine close to shoulders, allowing greater freedom in design of components.
