Alloy substrate composed of a variety of turning blades or other tools Boring

Structured into welded composite CBN blade and overall PCBN inserts; former is welded to the cubic boron nitride synthetic diamond composed of a variety of cemented carbide substrate turning inserts or other boring knives, The latter is the overall polycrystalline structure of the blade. Early CBN inserts welded composite films mainly based, is currently still widely used, its Diamond blade is the ability to achieve high efficient abrasive grinding even "turning instead of grinding", but in the actual production machining, met a lot of intermittent machining hardened steel, hard cast iron, gray iron, sand, white cast iron in these areas, cubic boron nitride composite welding (PCBN) inserts often chipping knife fight, so there are a monolithic CBN blade.
