Skiving And Skiving Toothing For Gears
It is, in fact, a technology which, using hard metal hobs, with dimensions of diameter suitable for the part to be made, allows us to work different materials with hardnesses up to 61/62 HRC, at rather low costs. This technique involves finishing the flanks of the teeth, removing about a tenth of a millimeter on the chordal (or Wildhaber) level, guaranteeing a Din 3962, Grade 6 machining quality.
It is also possible to repair teeth by reducing the chordal level by even a few hundredths of a millimeter, working to correct any errors in concentricity, helix deviation and tooth profile.
Skiving is an indispensable technique especially in the case of small and bulky teeth that would prevent the use of grinding wheels. In these cases, the required discharge space would be excessive and this would affect shoulders or parts that, according to the drawing, must not be touched, on the contrary, thanks to the reduced size of the skiving hobs (diameters up to 24 mm), it has no place any kind of inconvenience during the processing phase.
