De Beers公司生产了一种立方氮化硼基的DBC80新型超硬材料。用DBC80制造的刀片被作成焊接件形式或可换式刀片(装夹在标准刀杆上)。在上述两种场合下,刀片都有硬质合金垫片和薄薄的工作层(在一个面上)。DBC80与Amborite材料和DBC50不同之点是,立方氮化
De Beers produces a new type of cubic boron nitride based DBC80 superhard material. Blades made with DBC80 are made as welded parts or interchangeable inserts (mounted on standard arbor). In both cases, the inserts have carbide inserts and a thin working layer (on one side). The difference between DBC80 and Amborite material and DBC50 is cubic nitridation
