Why is carbide cutting tools less standard than high speed steel cutting tools?
Because the hard alloy material rigidity is better, the brittleness is bigger, the toughness is relatively bad, namely is easier than the high speed steel cutting tool to break off, after grinding blunt, the force is more complex. Greater resistance. Do you want your expensive tool to break?.
Because carbide cutting tools wear better than high speed steel cutting tools.
Because the hard alloy material rigidity is better, the brittleness is bigger, the toughness is relatively bad, namely is easier than the high speed steel cutting tool to break off, after grinding blunt, the force is more complex. Greater resistance.Cemented carbide: an alloy material made from powder metallurgy by hard metals and bonded metals of refractory metals. Hard alloy is widely used as a tool material, such as turning, milling, planing, drilling, boring, used for cutting cast iron, non-ferrous metals, plastics, chemical fiber, graphite, glass, stone and steel, can also be used for cutting steel, stainless steel, high manganese steel, tool steel and other hard processing materials. Now, the cutting speed of new carbide tools is several times that of carbon steel. Hard alloy with high hardness, strength and toughness, good wear resistance, heat resistance, corrosion resistance and a series of excellent performance, especially high hardness and wear resistance of it, even at a temperature of 500 DEG C also remained unchanged, at 1000 degrees C still have high hardness.
