Skiving

 

Skiving is a modern processing technique of tooth profile finishing, performed with CNC gear-cutting machines of last generation.

It is, in fact, a technology that, by employing carbide hobs with diameter sizes appropriate to the detail to be performed, allows processing different materials with hardness up to 61/62 HRC, at rather contained costs. This technique involves the finishing of the tooth flanks by removing about one-tenth of a millimeter on the chordal measurement (or Wildhaber), providing a Din 3962, grade 6 processing quality.

It is also possible to repair gears by reducing the chordal measurement by a few hundredths of a millimetre, being able to correct any errors in concentricity, helix deviation and tooth profile.

Skiving is an indispensable technique, especially in case of small gears and encumbrances that would prevent the use of grinding wheels. In these cases, the requested grinding undercut would be excessive and this would affect shoulder screws or parts that, in drawing, must not be involved; on the contrary, thanks to the reduced size of skiving hobs (up to 24-mm diameter), there is no kind of inconvenience during the processing stage.
