Due to advances in powder metallurgy technology, there has been wide application getting high hardness sintered metal. One manufacturer has developed 53rc-60rc containing tungsten, nickel alloy titanium carbide powder, the hardness can be achieved. In the matrix structure of the nickel alloy carbide particles hardness up 90rc. In the processing of these materials, the blade surface coated carbide inserts wear out quickly, the initial edge is polished, it is subtle vibrations due to the microstructure of the ultra-hard particles produced will accelerate blade wear. When processing such a high hardness materials, carbide blade may also be broken by the shearing force.
cbn blade provides a highly efficient method of processing high hardness powder metal containing tungsten and titanium carbide, and its advanced geometry can overcome slight vibration. A powder alloy processing users find that using cbn blade than the best carbide inserts 2,000 times longer life. Five with a flat blade cutter to feed speed 200sfm speeds and 0.007 inches / tooth workpiece machining high hardness, results than EDM faster 75%.
