The power skiving solution from Sandvik Coromant includes a solid bore, solid shank and indexable cutters. These tools are said to offer high tool accuracy with regard to run-out and pitch. Reconditioning can be performed as many as 10 times depending on the quality of the tool. The cutters feature a positive rake angle for light cutting action and the potential for dry machining.

According to the company, the power skiving cutters provide both high output and an optimized finishing profile. The tools are designed to meet customer specification and are said to be as much as 15x faster than shaping and more flexible than broaching. Applications include internal and external gears and splines, in addition to cylindrical spur and helical gears for automotive transmissions, and variety of other gears, coupling components, splines, shafts, synchronization rings and CV joint parts. 


  • Getting the Most Out of Hard Turning

    Traditionally, production of most parts made from hard or hardened materials, defined as those at or more than 45 HRc, required dedicated grinding equipment and processes.

  • Broaching On A Lathe

    Producing a keyway, spline or similar longitudinal feature on a turned part usually necessitates an additional, time-consuming, secondary operation on a broaching or slotting machine. That means moving the part to and from a secondary operation, an extra setup, additional labor and hourly machine costs and all of the other headaches that go with secondary operations.

  • Precision Lathe Operations on a CNC Mill

    Sometimes a shop doesn’t do enough turning work to justify the purchase of a CNC lathe. But when it needs to produce precision turned parts, even if for a very small lot size, the shop needs a solution.
