CNMN BN-S20 Hard turning insert form cbn insert manufacturer Halnn tools
Hard turning process machining work piece which hardness above HRC45.There are many materials can use hard turning,such as bearing steel,gear steel ,surfacing hardened steel,Nickel-based alloys,ect.In current times ,quenching steel and Carburizing steel also begin to be used for hard turning.
Hard turning can replace grinding in some processing(like machining cylinder,end surface ect) ,not only save the processing time ,but also save the processing costs.And it also obtain excellent roughness which can be below Ra0.4.So there are more and more manufacturers interested in hard turning process instead of grinding.
The key of hard turning process is the choice of the cutting tools.Many customers want to try hard turning ,but they didn’t know how to choose the most suitable cbn insert ,so they
will waste much time in the processing.

Hard turning usually use dry cutting ,and the temperature of insert tip wil be very high,if use cbn insert ,most heat can be taken away by the cutting chips.So CBN insert will be the most suitable cbn insert.
Halnn always to devote to making the world have no difficult to machine materials.
