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.

So please check the following Halnn superhard product BN-S20 application case:

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.
