CoroMill® 178
Solid carbide and PM-HSS power skiving tools for gear and spline production with high output
High productivity and flexibility
Possible to machine the complete component in a multi-task machine or machining centre in one single set-up, which shortens production time, improves quality and reduces handling and logistics costs.
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.
Application area
- Optimized for single setup on a multi-task machine
- For roughing and finishing operations
- Main industry segments to target are automotive, aerospace, general machining, energy industries and MTM builders

What is power skiving?
Power skiving is a continuous cutting process that enables all machining to be carried out in one single set-up. In essence it is a combination of hobbing and shaping. The intersecting angle between tool and gear axis and the revolution speed is decisive for productivity.
A further advantage of the machining method is its capability to machine close to shoulders, allowing greater freedom in component design.
