PCBN Insert Continuous Finish Turning 16Mn5 Gear Wheel Steel Gear wheel Inner Bore
1. Halnn Tools PCBN Insert Continuous Finish Turning 16Mn5 Gear Wheel Steel Gear wheel Inner Bore
There are many difficulties on hard turning Gear after heat treating:
(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 hole), 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.
