Description
Technical field
The present invention relates to a kind of rare earth modified tungstenio binder diamond angle abrasive disc and manufacture method thereof.
Background technology
Buddha's warrior attendant SHIJIAO abrasive disc is the kit of angle grinding machine, is widely used in various stone material, glass, ceramic cutting and polishing. Conventional Buddha's warrior attendant SHIJIAO abrasive disc carcass includes iron-based and cobalt-based. Iron-based matrix has higher mechanical property, and diamond also has good wettability, and with low cost, but its self-sharpening is not good enough; And cobalt-based carcass has good formability and sinterability, the wettability of diamond is good, cohesive force is big, good toughness, and self-sharpening might as well, it it is the most widely used a kind of carcass in diamond tool field, but the diamond on cobalt-based carcass holds by mechanical system, causes that diamond particles can not effectively cut completely in exposure, but also can make its severe attrition because of the effect of pulling capacity, make diamond particles obscission serious, affect grinding efficiency and the service life of Buddha's warrior attendant SHIJIAO abrasive disc. In the metallic bond manufacturing carcass, add a small amount of tungsten powder sometimes, this is because tungsten is except producing solid molten strengthening with other metals, or carbide, can react with diamond and produce enhanced primary treatment power, compared with simply mechanically diamond being wrapped up with general metallic bond and being fitted together to, the generation of enhanced primary treatment power is conducive to improving carcass to the power that plates of diamond, enhancing hold, it is therefore contemplated that tungstenio binder diamond angle abrasive disc will have the performance of excellence. But the fusing point of tungsten is up to 3940 DEG C, it is sintered, as metallic bond, the ability that required temperature is born considerably beyond diamond using tungsten, it is easily caused the graphitization of diamond particles, what therefore all adopt at present mostly is the relatively low tungsten carbide-base bonding agent of sintering temperature, and simple tungsten based anchoring agent have not been reported. But tungsten carbide-base bonding agent wolfram element on the one hand itself has formed carbide, and its effect producing enhanced primary treatment power with diamond is weakened;On the other hand the sintering temperature needed for tungsten carbide-base bonding agent is still higher, be only suitable for the good diamond of heat resistance with the use of, relatively costly, range of application is narrow. Therefore, if the problem that tungsten based anchoring agent sintering temperature is high can be solved, it will the manufacturing technology for Buddha's warrior attendant SHIJIAO abrasive disc opens the gate that a fan is new.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art part, it is provided that a kind of rare earth modified tungstenio binder diamond angle abrasive disc and manufacture method thereof.
One of the technical solution adopted for the present invention to solve the technical problems is:
A kind of rare earth modified tungstenio binder diamond angle abrasive disc manufacture method, including:
1) diamond dust and rare earth modified tungstenio bonding agent being sufficiently mixed, this rare earth modified tungstenio bonding agent comprises following components by mass fraction: 40��75 parts of tungsten, 2��6 parts of nickel, ferrum 2��5 parts, 8��30 parts of stannum, copper 7��20 parts, 0.4��1 part of manganese, 0.1��1 part of rare earth element;
2) corresponding mould is utilized after said mixture cold moudling, vacuum heating-press sintering, sintering temperature 900��960 DEG C, sintering pressure 140��200KN, sintering time 25��35 minutes will to be carried out by the profile of required Buddha's warrior attendant SHIJIAO abrasive disc carcass;
3) after vacuum heating-press sintering, carry out HIP sintering, sintering temperature 840��900 DEG C, sintering pressure 80��120MPa, sintering time 5��10 minutes, obtain Buddha's warrior attendant SHIJIAO abrasive disc carcass;
4) Buddha's warrior attendant SHIJIAO abrasive disc carcass is installed on the abrasive disc matrix of angle, obtains Buddha's warrior attendant SHIJIAO abrasive disc.
In one embodiment: described diamond dust is artificial monocrystalline diamond powder, and its diamond concentration is 50%��100%, and granularity is 35/40��170/200.
In one embodiment: described rare earth element is at least one in the compound of lanthanum or lanthanum.
In one embodiment: the compound of described lanthanum is at least one in lanthana, lanthanum sulfate, Lanthanum (III) nitrate, lanthanum chloride.
In one embodiment: described step 4) in, Buddha's warrior attendant SHIJIAO abrasive disc carcass is welded on the abrasive disc matrix of angle, obtains Buddha's warrior attendant SHIJIAO abrasive disc.
In one embodiment: described step 4) in, by Buddha's warrior attendant SHIJIAO abrasive disc carcass hot pressed sintering on the abrasive disc matrix of angle, obtain Buddha's warrior attendant SHIJIAO abrasive disc.
The two of the technical solution adopted for the present invention to solve the technical problems are:
A kind of rare earth modified tungstenio binder diamond angle abrasive disc manufactured according to rare earth modified tungstenio binder diamond angle abrasive disc manufacture method.
Diamond concentration of the present invention is industry slang, refers to the quality of diamond in unit volume metallic bond, with 4.4 carats/centimetre3For diamond concentration 100%.
Carcass of the present invention is industry slang, refers to the metal sinter of trapping gold hard rock, plays the effect holding diamond, as the working portion in diamond tool, for instance cutter head, working lining etc.
Heretofore described artificial single crystal's diamond dust is product sold in the market.
Heretofore described tungsten, nickel, ferrum, stannum, copper, manganese are elemental metals powder, are product sold in the market.
Heretofore described lanthanum, lanthana, lanthanum sulfate, Lanthanum (III) nitrate, lanthanum chloride are product sold in the market.
The technical program is compared with background technology, and it has the advantage that
1. rare earth modified tungstenio bonding agent provided by the present invention, each component complements each other, sintering temperature is reduced to, from nearly 4,000 degrees Celsius, the scope that diamond can bear, solve tungstenio bonding agent all the time and be difficult to the defect of practical application because sintering temperature is high, it is successfully realized the manufacture of tungstenio binder diamond angle abrasive disc, and utilize tungsten and diamond to react the enhanced primary treatment power produced, improve diamond particles hold on Buddha's warrior attendant SHIJIAO abrasive disc carcass, the Buddha's warrior attendant SHIJIAO abrasive disc hardness obtained is high, wear-resistant, the new situation has been started in manufacture for high-performance diamond angle abrasive disc.
2. the present invention adds rare earth element in tungstenio bonding agent, there is the effect controlling melts combine grain growth, and have employed the compound of rare earth element in the preferred embodiment, grain size controllability is better, the metallic bond crystal grain obtained will not be excessive or too small, particle diameter is more stable, enhance hardness and the toughness of Buddha's warrior attendant SHIJIAO abrasive disc, also improve anti-wear performance and impact resistance, effect is better than rare earth element simple substance, it is further provided the new approaches of high-performance diamond angle abrasive disc manufacture method.
