Hard turning Gear after heat treating has following difficulties:

  1. The hardness of the Gear will reach HRC58~62, the insert will wear rapidly, which will affect the processing efficiency.
  2. Some Gears exist interrupted turning condition (end surface has holes), the cutting tools will be easily chipping, so the costs will be high.
  3. For large scale Gears, the hardness after heat treating will be high, and the deformation also will be large, it will require high wear resistance and impact resistance on the cutting tools.

Yusu Super Hard Tools developed solid CBN inserts to solve above problems. Yusu solid CBN inserts will make sure the excellent wear resistance, anti-fracture properties and  strong impact resistance. The Inserts Grade and corresponding cutting data as follows:
