High Speed Cutting Brake disc with CBN Cutting Tool full form

CBN/PCD inserts are the best choice for high speed and precision machining of high hard material, difficult to cut material and cast irons. They can be used for machining abrasive resistance alloy cast iron like brake disc and brake drum; Or machining normal gray cast iron with high speed, like engine cylinder and cover; Or machining alloy cast iron and alloy cast steel, like roller, slurry pump; Or used for machining some tough material such as hardened steel, bearing steel and die steel;  They also can be used for machining high temperature alloy like aeroengine.

Why Choose Halnn Tools  CBN Cutting Tool ?

(1) Improve Efficiency: Compared with coating carbide insert, it can realize high speed machining,and the suitable linear speed will be: 250~450m/min for roughing process, 450~800m/min for finishing process.

(2) Improve Tools Durability: The tool life of Halnn CBN Insert is about 15 times of carbide insert.
(3) Improve Roughness: Halnn BN-K20 and BN-S30 can receive the roughness within Ra1.6, is much better than carbide insert.
(4) Characteristics of Halnn CBN inserts: BN-S30 and BN-S300 adopt non-metal adhesive, improved the thermal conductivity and the strength, not only extend the insert lifetime, but also improve the impact resistance. And BN-S30 can be used for roughing process, BN-S300 can be used for finishing process. BN-K20 and BNK30 belong to brazed pcbn insert, both of them can be used for finishing process.
