1. Halnn CBN Materials for machining Gray Cast Iron

2. The cutting condition of Halnn CBN Insert

3. The advantages of Halnn CBN Inserts machining gray cast iron part
(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. And it also be suitable for the high speed milling with 1500m/min or above. The efficiency will be about 2 times more than cabide insert.
(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 extand 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. the tools of processing brake disc, brake drum as follows:
