PublishedDate：2017-12-13
Halnn Superhard, as the predecessor of China Superhard cutting tools, is a professional enterprise machining brittle and hard materials with cbn inserts and have already enjoyed high reputation in superhard cutting tools field, and have our own advantages especially in some field, such as “turning instead of grinding”, high hardness heavy cutting, and high speed machining cast iron.
Specific for hard turning field, Halnn recommend 6 types cbnmaterials for reference, and already covered continuous turning to interrupt turning type, details as follows:
