Notes:
PCBN tools are used worldwide for machining of hardened steel parts in automotiveindustries. Because cutting by PCBN tools has many advantages, which are high-precision, highefficiency,high-flexibility and low total machining cost, compared with conventional grindingmethods. But in heavy interrupted cutting of hardened steel, the tool life is not so stable by suddenbreakage of the cutting edge, and total cost of cutting by PCBN is not so economical compared tothe grinding. So the conventional grinding is still main process in such applications. Recently,demand for decreasing machining cost has grown in heavy interrupted cutting and much tougherPCBN material is required. To solve this problem, new PCBN has been developed. New PCBN hasvery fine and homogeneous microstructure to increase the toughness of sintered body that itprovides a reliable tool life for heavy interrupted cutting. The features and cutting performances ofnew PCBN are described in this report
