SNGN120408 CBN Cutting Tool full form Finish Turning Hardened Steel Gears with high efficiency
1. Halnn Tools SNGN120408 CBN Cutting Tool full form Finish Turning Hardened Steel Gears
The hardness of the gears after heat treatment is about HRC58~62, traditional technology is grinding process. With the increasing competition, grinding process already can’t meet the customers requirements on the high efficiency and low costs. With the appearance of cbn inserts, turning instead of grining process become widely used in most industries, which not only help improve the efficiency, reduce the machinery costs and repairing costs, and is environmental without coolant.
2. Why we Choose Halnn Tools SNGN120408 CBN Cutting Tool full form Finish Turning Hardened Steel Gears ?
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.
