Scudding® / Power Skiving tools Star SU and Profilator have formed an alliance to manufacture Scudding® tools for the global market. Scudding® is a continual gear cutting process which makes both the production of external and internal gears, as well as spur and helical gearing possible. As another great advantage, the Scudding ® technology allows the machining of internal or external gears/splines without the need of an undercut or groove. The end of the gear can be a defined/ programmed ramp of radius. Scudding® can compete with shaping, broaching, and other gear cutting processes to...

Power Skiving for quicker, more efficient and productive The high number of cuts per time unit not only leads to a very short cycle time, it produces high quality gears with a low surface roughness. We produce Power Skiving tools for all solutions and machines present on the market.

Chamfer-roller tools n For gears with parallel chamfers n For gears with comma type chamfers n A burr which is not removed may break off during use and damage bearings or gears in gearboxes. n Over-carbonizing may result in too much pressure being exerted on sharp gear lateral surfaces, which might then break. n A hardened burr may lead to premature wear of tools in subsequent finishing operations. n Removal of very sharp burrs reduces the risk of tool handling injuries. With our chamfer-roller tool, you can chamfer and roll your gears at the same time. The secondary burr that is generated...
