The processing by shaving cutters is adopted for finishing a small amount of gear tooth surface after processing with hob and / or shaper cutter.
Among the four types of shaving processes including Conventional, Diagonal, Underpass and Plunge cut, Plunge cut is mostly applied in gear production lines of four-wheel vehicles and two-wheel vehicles because of its efficiency and longer tool life.
Super Coat Shaving Cutter and Fine Pitch Shaving Cutter in our lineup have demonstrated superior improvement in tool life and work piece accuracy.

Adjust the crossed axes angle between a work piece processed with hob and / or shaper cutter and shaving cutter at 5° to 15°and rotate them after meshing each other; sliding motion of the tooth surface enables fine finishing with only a slight amount of cutting.
The processing by shaving cutter is largely applied in gear production lines of auto mobiles and construction machineries because of its cost efficiency.
This processing is performed only before heat treatment. On the other hand, profile grinding is performed after heat treatment
Move the cutter from the lower location colored in blue to the upper location colored in red; contact point moves from left to right and enables the processing of the entire tooth.
In case of that the space between each gear is narrow, it may be difficult for conventional processing to be applied because of not enough crossing angle.
In such a case Underpass processing might be applied.
Move the cutter to the arrow direction colored in red; If fed in diagonal direction, meshing point will move from right edge A to left edge B of a work piece.
