Preferably, the group number of multiple groups cathode arc source target is 4 groups of aluminium for being arranged alternately and starting simultaneously in the step 7
Evanohm target and titanium chrome alloy target.
Preferably, the vacuum degree of the step 7 is 0.001Pa-0.01Pa.
In conclusion the invention has the following advantages: by high using high temperature to the raw material with diamond dust
Pressure compacting diamond dust obtain high rigidity and high-wearing feature away drill cuttings, have high-wear resistance and it is longer use the longevity
Life, while away drill cuttings are after shaping, carry out coating film treatment to the surface of away drill cuttings, improve the hardness, wear-resisting of away drill cuttings
Property and high temperature resistance, therefore compared with uncoated cutter, coated cutter allows using higher cutting speed, to improve
Machining efficiency；Or cutter life can be improved under identical cutting speed.Due between Coating Materials and machined material
Coefficient of friction it is smaller, therefore the rotary cut power of coated cutter be less than uncoated cutter.With tool sharpening, the machined surface of part
Quality is preferable.Since the comprehensive performance of coated cutter is good, therefore plated film carbide chip has preferable versatility, a kind of plated film
Away drill cuttings have compared with use scope.
