The present invention relates to a grinding tool mixed by abrasives. The grinding tool is made by mixing a first abrasive, a second abrasive and a binding agent according to the following ratio by volume. The mixed ratio by volume of the first abrasive to the second abrasive to the binding agent is from 1:3:8 to 3:1:3. The present invention has the advantages that satisfactory surface finishing quality can be ensured, and the polishing and grinding processing efficiency is effectively improved.

Description

The grinding tool that abrasive material mixes
Technical field
The invention belongs to grinding and polishing grinding tool preparing technical field, be specifically related to the grinding tool that a kind of difformity abrasive material mixes.
Background technology
As the important manufacturing process that obtains high accuracy, high surface finish, the polishing grinding technique occupies critical role in modern precision and super hot investment casting technology.The polishing grinding technique is to account for old process technology most, also is the process technology that ultraprecise is processed main utilization, and purpose is to remove breakable layer and the reduction surface roughness that preceding working procedure carries over, thereby obtains smooth finished surface.Because smooth finished surface can improve corrosion resistance, wearability, the fatigue strength of part and the performances such as sealing of part of material surface, the polishing grinding technique becomes one of key manufacture in fields such as Aero-Space, military affairs, medicine equipment, precision optical machinery, instrument and meter, optical component, electronic equipment.And improve the polishing lapping efficiency and reduce polishing lapped face roughness and cut down finished cost is the important research content of polishing field of milling always.
Multiple polishing Ginding process is grown up; as polishing technologies such as chemically mechanical polishing, float glass process polishing, ion beam polishing, electrobrightening, fluid polishing, fixed abrasive material polishing and magnetically grinding polishings etc.; no matter be discrete abrasive particle or fixation abrasive grain, the basic principle of most polishing Ginding process is to utilize abrasive product that surface of the work is carried out trace to remove the purpose that reduces surface roughness to reach.Up to the present, the technology of utilizing abrasive polishing to grind, its research direction mostly is to utilize the method that reduces grain diameter or obtain higher surface smoothness the grinding tool for preparing the abrasive material regular distribution, but can reduce material removing rate greatly, causes processing cost to increase.Therefore, study and a kind ofly can guarantee the attrition process quality, the novel precision grinding technology that can significantly improve lapping efficiency again, cuts down finished cost is extremely urgent.
Discover that utilize abrasive material to polish when grinding, polishing lapping efficiency and crudy are antagonistic relations.Its polishing grinding efficiency height of the abrasive material of big particle diameter, but the surface quality after its polishing grinding is relatively poor; Its polishing grinding efficiency of the abrasive material of small particle diameter is low, but the surface quality after its polishing grinding is better.Traditional research thinks that the particle diameter of abrasive material is having overwhelming superiority aspect material removing rate and the crudy, promptly changes polishing lapping efficiency and crudy by the mode that changes particle diameter.Current research finds that the shape of abrasive material is also being brought into play important effect aspect material removing rate and the crudy.The irregularly shaped particles of same particle size specification is compared with the particles having similar shapes material, and the material removing rate after its polishing is ground significantly improves, surface quality is poor.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the grinding tool that the object of the present invention is to provide a kind of abrasive material to mix has and can guarantee to obtain satisfied surface smoothness, improves the characteristics of polishing lapping efficiency effectively.
To achieve these goals, the technical solution used in the present invention is: the grinding tool that a kind of abrasive material mixes, and mixed according to following volume ratio by first kind abrasive material, the second class abrasive material and binding agent: first kind abrasive material: the second class abrasive material: the volumetric mixture ratio scope of binding agent is 1: 3: 8~3: 1: 3; First kind abrasive material is one or more the mixture in the polygon abrasive material of triangle, prismatic or band acute angle, and when being two or more mixture, the batch mixing ratio is any; The material of first kind abrasive material comprises: the mixture of one or more in diamond, diamond dust, schmigel, ceramic powder, aluminium oxide, carborundum, garnet, cubic boron nitride or the iron oxide, when being two or more mixture, the batch mixing ratio is any; The second class abrasive material is one or more the mixture in circular, oval or the square abrasive material, and when being two or more mixture, the batch mixing ratio is any; The material of the second class abrasive material comprises: the mixture of one or more in diamond, diamond dust, schmigel, ceramic powder, aluminium oxide, carborundum, garnet, cubic boron nitride or the iron oxide, when being two or more mixture, the batch mixing ratio is any; Binding agent can be with acrylate, epoxy resin, liquid-type adhesive, phenolic resins, melamine formaldehyde resin, acrylate or epoxy resin.
The average grain diameter of abrasive material is decided on the working condition of grinding tool.In general, the surface roughness Ra value after the processing arrives 0.02~0.3um, and the average grain diameter of the abrasive material that uses is in 10~500um scope.According to the different requirements of working (machining) efficiency, can suitably adjust difformity proportion of particles and the particle diameter of the two with processing rear surface quality.
The effect of binding agent is that discrete abrasive grain is combined, and makes to have stronger adhesion between abrasive material, can satisfy the requirement that polishing is ground.
Effective effect of the present invention is: because in the polishing process of lapping, the degree of depth of the abrasive material insert material of band acute angle or corner angle is darker, so aspect material removing rate, can be than a lot of greatly with the spherical abrasive material of particle diameter, square abrasive material with material, its negative effect has also increased the surface roughness that test specimen is ground in polishing when significantly increasing material removing rate.Vice versa.So the present invention makes full use of the pluses and minuses of difformity abrasive material, and the difform abrasive mixed of two classes is lumped together.It polishes grinding effect and shows that though the surface roughness value after polishing is ground is higher slightly than the abrasive material that the polishing Grinding Quality is good in the compound, its working (machining) efficiency has raising significantly.
