CBN300 is an impact-resistant grade obtained by changing the particle size by special process on the basis of CBN30, which can be used for interrupted cutting. CBN300 is a pure CBN sintered body with a high PCBN content (90%). It has good wear resistance, excellent thermal conductivity and impact resistance. Compared with the existing PCBN products, it is a new and more mature PCBN product. It can be used for rough finishing of pearlite gray cast iron, roughening of hardened steel, processing of chilled cast iron, processing of manganese steel and even processing of hard alloys. Due to its good impact resistance, the CBN300 can be used not only for turning hard materials (HRC>45), but also for excellence in milling workpieces, completing the leap of PCBN inserts from turning applications to milling applications.
