1.The introduction of cutting tool
Cutting tool of numerical control treatment must get used to numerical control machine tool high speed, efficient with the characteristic with automation high rate. Numerical control milling cutter basically is divided from appearance to make the same score bottom knife (upright milling cutter) , round nose knife and ball knife, if graph 1-1 place is shown, from cutting tool performance characteristics cent is white steel knife, flying knife and alloy knife. Machine actually in the factory in, the most commonly used cutting tool has D63R8, d50R6, d35R5, d35R0.8, d30R5, d25R5, d20R4, d20R0.8, d16R0.8, d12, d10, d8, d6, d4, d3, d2.5, d2, d1.5, d1, d0.5, d10R0.5, d8R0.5, d6R0.5, d4R0.5, r5, r4, r3, r2.5, r2, r1.5, r1 and R0.5.
Alloy knife tigidity is good, not easy generation plays a knife, the effect that is used at finish machining mould is best, alloy knife and white steel knife have side edge euqally, copper of mill of essence of life often uses its side edge when fair straight wall.
