The Introduction of PCD The PCD (Polycrystalline diamond) is a composite material, consisting of sintered diamond particles with a metallic binder. Diamond is the hardest material in absolute terms and therefore also the most resistant to abrasion. Used as a cutting tool, it has a good wear resistance, and a yield superior to traditional sharp carbide. The machined surface roughness with the PCD can reach comparable to the adjustment. Main applications ▲Processing of non-ferrous ▲Aluminum alloys with high or low silicon content (pistons, engine blocks engine, wheels, carburetors, connecting rods, gear boxes, cylinders for brakes, etc.). ▲Bronze and copper alloys (copper manifolds, engine bearings, bushings, connecting rods eyes, locations pumps etc.). ▲Tungsten carbide (trafilatori rollers and other components sintered etc). ▲Pieces composed of aluminum and lead, aluminum engine blocks with cast iron pipes reported ▲Processing of non-metallic materials ▲Very abrasive materials, such as ceramics industrial uncooked. ▲Some fired ceramic: zirconia aluminum oxide, such as spark plugs and insulators.
▲Glass, plastics with glass fibers, carbon fibers.
The Introduction of PCBN
PCBN has the characteristics of high thermal stability, high hardness, high wear resistance and. It`s inert to iron family element, hence PCBN is mainly used for the machining of high hardness and hard processed ferrous materials, such as d facing alloys, harden steel, pearlitic gray cast iron, high temperature alloy, high-speed steel, hard facing alloys, Ni-Cr alloy, powder metallurgy metals.
