BN - S20 Solid Square CBN inserts High Speed Machining Gear Wheel Steel Gear wheel High Heat Resistance
1. Halnn Tools Solid Square CBN inserts High Speed Machining Gear Wheel Steel Gear wheel
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.
2. Why we Choose Halnn Tools Solid Square CBN inserts High Speed Machining Gear Wheel Steel Gear wheel ?
Halnn Tools, previous Henan Superhard Materials Institute, with more than 10 years experience on superhard cutting tools, has researched different cbn grade specific for hard turning gears. Halnn PCBN Insert also realize interrupt turning gears, and help many customers slove their problems and lower the tool costs.
