 CBN insert hard turning quenched steel 

In general, when hard turning hardened steel with CBN insert ,different tool wear mechanisms occur, such as: abrasion, adhesion, oxidation and even some diffusion, which act simultaneously and in proportions depending mainly on the temperature.During machining, temperature increased continuously and, after around 30 seconds, it became stable.

Halnn researched new cbn insert materials to help customers to solve their problems on hard turning harded steel.The CBN Insert materials as follows:

BN-S20 Solid CBN insert (include universal grade ,SNMN,CNMN,RNMN,TNMN,DNMN,RCMN,RCMX series)

BN-H21 Compound PCBN insert (include universal grade ,TNGA,WNGA,CNGA,DNGA,VNGA,VCGW series)

Halnn is a professional manufacturer of cbn insert,mainly for high speed and hard turning process for high hardness work pieces.
