Abstract
The invention relates to a special cutting tool composite material used in aluminum material cutting processes. The invention relates to the technical field of cutting tool composite materials. A production method of the material comprises steps that: high-strength ultra-fine-crystal-grain cemented carbide produced with a low-pressure vacuum high-temperature sintering technology is used as a coating substrate of diamond-like carbon; before the diamond-like carbon is coated, a cemented carbide rake face is subject to surface treatment with a wet sand blast and wet polishing technology, and is washed; a Cr layer, which serves as a transition layer, is pre-coated on the polished cemented carbide rake face with a low-temperature physical coating technology; with the low-temperature physical coating technology, the diamond-like carbon is coated on the surface of the cemented carbide substrate; after cemented carbide is coated by using the diamond-like carbon, the cemented carbide rake face is processed with the wet polishing technology. The material can be used for processing all types of aluminum materials. With the material, the cost of cutting tools can be reduced.

Technical field:
The present invention relates to the cutter technical field of composite materials, be specifically related to the special-purpose cutter matrix material of a kind of aluminium cut.
Background technology:
The existing cutter material of cut aluminium has two kinds: wimet and diamond.The high temperature y alloy y that the speed of inserted tool cutting aluminium is poorer than the speed surfaceness low, that stock-removing efficiency is low, wear resistance is low, the life-span is short, processed of diamond cutter cutting aluminium, can not cut Si >=12%; But intensity is high, good toughness, cost are low, about 20 yuan/sheet; The speed of diamond cutter cutting aluminium is better than the speed of inserted tool cutting aluminium surfaceness high, that stock-removing efficiency is high, wear resistance is high, the life-span is long, processed, can process all aluminiums; But intensity is low, poor toughness, cost high, about 120 yuan/sheet.
And sintered carbide tool material can only use PM technique production now, and the diamond cutter material can only adopt HTHP synthetic technology to produce.
Summary of the invention:
The purpose of this invention is to provide the special-purpose cutter matrix material of a kind of aluminium cut; Two kinds of cutter materials weakness separately before it has overcome can be processed all aluminiums, has both kept the H.T. of wimet and the high-wearing feature of quasi-diamond; Improve the cutting speed of cutter again; Then improve the surface quality and the stock-removing efficiency of workpiece, simultaneously, also reduce the cost (about 30 yuan/sheet) of cutter.
In order to solve the existing problem of background technology; The present invention adopts following technical scheme: its operation steps is: adopt the coated substrates of the high-strength ultra-fine grained wimet of low-voltage vacuum high temperature sintering technology manufacturing as quasi-diamond; Before quasi-diamond applies, adopt wet shot sand and wet tumbling technology that the wimet rake face is carried out surface treatment and cleaning, on the wimet rake face of polishing, adopt low-temperature physics paint-on technique (abbreviation DLC) to apply the thick Cr of one deck 0.1-1.0 μ m in advance as excessive layer; Then; Adopt low-temperature physics paint-on technique (being called for short DLC), be coated to the thick quasi-diamond of 1.0-10.0 μ m on the surface of matrix wimet, last; Wimet adopts the wet tumbling technology that the wimet rake face is handled after quasi-diamond applies.
The prescription of described high-strength ultra-fine grained wimet is: 88-95%WC+5-12%CO+0.1-1.5%Cr.
Described quasi-diamond is: 85-95% diamond+2-8% graphite+0.5-5% uncombined carbon.
The present invention has following beneficial effect:
1, improve quasi-diamond and the bonding force of wimet and the coating thickness of quasi-diamond, and then the work-ing life of improving cutter;
2, improve quasi-diamond and the bonding force of wimet and the coating thickness of quasi-diamond, simultaneously, improve the thick poor degree in its surface,, the possibility that produces built-up edge is reduced to minimum to reduce cutting resistance, thereby, the work-ing life of improving cutter;
3, improve the bonding strength of diamond and wimet;
4, raising improves the work-ing life of cutter and reduces its cost;
5, improve the work-ing life of cutter.
Embodiment:
This embodiment adopts following technical scheme: its operation steps is: its operation steps is: adopt the coated substrates of the high-strength ultra-fine grained wimet of low-voltage vacuum high temperature sintering technology manufacturing as quasi-diamond; Before quasi-diamond applies; Adopt wet shot sand and wet tumbling technology that the wimet rake face is carried out surface treatment and cleaning; On the wimet rake face of polishing, adopt low-temperature physics paint-on technique (being called for short DLC) to apply the thick Cr of one deck 0.1-1.0 μ m in advance, then, adopt low-temperature physics paint-on technique (being called for short DLC) as excessive layer; Be coated to the thick quasi-diamond of 1.0-10.0 μ m on the surface of matrix wimet; At last, wimet adopts the wet tumbling technology that the wimet rake face is handled after quasi-diamond applies.
The prescription of described high-strength ultra-fine grained wimet is: 88-95%WC+5-12%CO+0.1-1.5%Cr.
