Description
Technical field
The present invention relates to a kind of preparation method, belong to super hard abrasive tool making field with metal binder cubic boron nitride grinding wheel of self-lubricating function.
Background technology
Cubic boron nitride (CBN) is after diamond, adopts the static pressure catalyst method that is similar to diamond synthesis at first to make second kind of successful artificial superhard material in nineteen fifty-seven by U.S. physical chemist R.H.Wentorf.Compare with diamond, CBN also has than the superior heat endurance of diamond with to the chemical stability of ferrous metal except that having characteristics such as high rigidity, high-wearing feature, low-friction coefficient.Present stage, the various emery wheels of being made by the CBN abrasive material have been used to the efficient precise grinding processing of nickel base superalloy, to substitute traditional corundum abrasive emery wheel.
Be pointed out that, although the CBN abrasive particle has excellent antiwear characteristic, but because nickel-base alloy belongs to typical high-strength tenacity difficult-to-machine material, therefore when adopting common CBN emery wheel that it is carried out high efficient grinding, process the lubricating status that the arc district remains excellence if can not take corresponding supplementary measures to guarantee, strong friction effect between workpiece and the abrasive particle will cause processing skin-material and emery wheel generation high temperature adhesion, cause the workpiece grinding burn.In addition, grinding high temperature also makes the CBN abrasive particle be vulnerable to fire damage, causes that the emery wheel passivation is fast, loss is big, the life-span is undesirable, and this will seriously restrict giving full play to of CBN super-abrasive grinding wheel processing potential.For strengthening the cooling and the lubricating ability of grinding arc area, the method that generally adopts is to use high-pressure high-flow cooling fluid cast grinding area at present, but cooling fluid all can cause severe contamination to environment in each stages such as manufacturing, use, processing and dischargings.Along with social development and environmental consciousness strengthen, their application is subjected to strict restriction just day by day.In recent years, people have also developed a series of novel green cooling technologies successively, as MQL, the pneumatic spraying cooling of low temperature, steam cooling, CO
2Gas cooled etc.Although these novel cooling technologies are used in machining such as the turning of difficult-to-machine material, milling on a small quantity, obtained some challenging achievements, remarkable effect is not seen in the application in grinding always.Reason mainly is, in reciprocal grinding process, hindered cooling mediums such as grinding fluid or air-flow and enter the arc district because emery wheel rotates " airbond " of generation at a high speed, thereby the processing district in fact still is in approximate dry abrasive cutting state.Though interior cooling emery wheel can overcome the defective that cooling medium can't enter grinding arc area to a certain extent, still be difficult to drop into practical at present.
Summary of the invention
The object of the present invention is to provide a kind of preparation method with metal binder cubic boron nitride grinding wheel of self-lubricating function.
The powder particle that the present invention will have a lubricating function is introduced and to be contained in the Ti alloy with common composition grinding wheel bond layer material, and makes the abrasive wheel forming blank; Again blank is put into heating furnace and carried out the activated sintering of vacuum liquid phase, produce self-lubricating metal binder cubic boron nitride (CBN) emery wheel.
(1) be hexagonal boron nitride (HBN) to the powder particle composition with lubricating function that contains the introducing of Ti alloy, both mixtures are formed the grinding wheel bond layer material jointly, and the content of HBN particle accounts for 5 ~ 15% of both gross masses; The described Ti of containing alloy is Ag-Cu-Ti alloy or Cu-Sn-Ti alloy;
(2) with the grinding wheel bond layer material, the mixture mechanical agitation that promptly contains Ti alloy and HBN particle is even;
(3) press emery wheel metallic matrix/bonding agent layer material/cubic boron nitride abrasive grain sequentially built abrasive wheel forming blank;
(4) the emery wheel blank is put into vacuum drying oven, carried out the activated sintering of vacuum liquid phase in 5 ~ 20 minutes under the technology in 900 ~ 1000 ℃ of heating-up temperatures, insulation, make contain the Ti alloy respectively with hexagonal boron nitride particles and cubic boron nitride abrasive grain generation chemical reaction, make the self-lubricating metal binder cubic boron nitride grinding wheel.
Principle of the present invention and advantage are as follows:
Metallic bond layer to cubic boron nitride (CBN) emery wheel is introduced hexagonal boron nitride (HBN) particle with lubricating function, can utilize mechanical swiping and squeezing action in the Grinding Process to impel HBN particle release film forming, thereby significantly strengthen the lubricated behavior between emery wheel and the workpiece, reduce grinding and generate heat, reduce grinding temperature, improve crudy, promote giving full play to of cubic boron nitride superhard abrasive grinding wheel grinding potential.
Moreover, introduce lubricant component---chemical reaction can take place with the Ti alloy that contains of bonding agent layer in hexagonal boron nitride (HBN) particle in vacuum liquid phase activated sintering process, formation has the interface microcosmic transition structure of better mechanical property, guarantees excellent Physical Match and chemical compatibility between the two.In addition, hexagonal boron nitride (HBN) also can significantly strengthen the adhesive force between lubricating film and the CBN abrasive particle, avoids selecting improperly to cause that lubricating film is difficult to that film forming is sprawled or lubricating film is poor in abrasive particle surface hold facility, breakage unfavorable phenomenon such as come off easily because of the lubricant component characteristic.
Process route: (1) bonding agent layer material (containing Ti alloy and hexagonal boron nitride particles) is in the ratio batching of appointment; (2) the bonding agent layer material mechanical is stirred; (3) make the emery wheel blank; (4) blank is put into heating furnace, vacuum liquid phase activated sintering moulding again.
