When to use CBN inserts?
CBN (Cubic Boron Nitride) inserts are a type of superhard material tool that has significant advantages in machining high-hardness materials due to its extremely high hardness and wear resistance. It is usually used to cut materials with a hardness exceeding HRC45, such as hardened steel, powder metallurgy, high-temperature alloys, and hardened cast iron. Since these materials are extremely wear-prone to the tool, ordinary carbide inserts are difficult to handle, while CBN inserts can provide a longer service life.
CBN inserts also play an important role in the field of high-precision machining. For example, the manufacturing of parts such as automotive gears, bearing seats, and molds has strict requirements on dimensional accuracy and surface finish, and the stability of CBN inserts makes it an ideal choice. Due to its extremely high heat resistance, it is particularly suitable for high-speed cutting, and can maintain good cutting performance even under conditions of no coolant or minimal lubrication, thereby improving production efficiency while reducing dependence on cutting fluids.
Jinxin CBN inserts perform well in high-precision machining and slightly intermittent cutting, such as the finishing of hardened steel gears, which can ensure stable cutting results. You can also contact us to help you solve your customized needs.
