Description

A kind of CBN emery wheel
Technical field
The present invention relates to a kind of new ceramics base CBN emery wheel of grinding metal works.
Background technology
Along with industrial expansion, the requirement of machine components machining accuracy, process velocities etc. such as iron and steel is improved day by day, CBN Precision Machining instrument becomes in the world the competitively focus of research and development.CBN grinding tool good processing accuracy, the grinding efficiency height.Patent ZL200310116239.7 has announced a kind of ceramic base CBN emery wheel, and adopting CBN and black SiC is abrasive material, but because the SiC thermal conductivity is bad, emery wheel is sticking easily bits in high-speed grinding, are difficult to adapt to high-speed grinding.And AlN has good thermal conductivity and lubricity, its hardness of the abrasive grain and Al 2O 3Hardness of the abrasive grain is similar, so adopt CBN and AlN especially to be suitable for high-speed grinding as the ceramic base CBN emery wheel of compound abrasive.
Summary of the invention
The purpose of this invention is to provide a kind of new ceramics base CBN emery wheel, effectively solve the Speed Grinding problem of automobile engine and iron and steel parts such as air-conditioning, freezer compressor.The technical scheme of its solution is as follows: a kind of new ceramics base CBN emery wheel, to form by bond, abrasive material and other additives, and described abrasive material mainly comprises CBN and AlN, and preferred abrasive material proportioning (mass percent) is as follows:
CBN abrasive material 60～90% AlN abrasive materials 10～40%
Grinding wheel formula is (mass percent): abrasive material 70～77%, bond 20～26%, other additives 3～4%.The preferred Al-Si-B microcrystalline glass in series of bond powder wherein, its raw material consists of SiO 2: 30～35%, Al 2O 3: 20～25%, B 2O 3: 15～23%, Na 2O:10～15%, K 2O:5～7%, LiF:2～7%.The dextrine powder of other additives preferred 1～2%, 1～2% methocel solution, and 0～1% walnut shell powder.
The present invention is with CBN and the AlN main abrasive material as emery wheel, because aluminum nitride particle has good thermal conductivity and good lubricity, so the present invention's grinding heat energy when grinding work piece is derived rapidly, not only the workpiece that goes out of grinding does not have burn, crackle, distortion but also because grinding temperature reduces the sticking bits of emery wheel phenomenon is reduced, and has increased the grinding efficiency of emery wheel.
The specific embodiment
Embodiment 1:
Emery wheel is formed: abrasive material 76%, bond 20%, dextrine powder 1%, methocel solution 2%, walnut shell powder 1%.
Abrasive material proportioning wherein: CBN abrasive material 60%, AlN abrasive material 40%, granularity is 170/200.
Bond is 270 purpose microcrystalline glass powders, and its proportioning is as follows: SiO 2: 30%, Al 2O 3: 22%, B 2O 3: 20%, Na 2O:15%, K 2O:7%, LiF:6%
Elder generation carries out abrasive particle wetting with methocel solution, add bond, dextrine powder and walnut shell powder then, fully mixes more than 30 minutes, crosses 60 mesh sieves, makes the abrasive wheel forming material.The abrasive wheel forming material is put into mould inner pressure make the annulus cylindricality.After the air dry 24 hours, put into the drying box drying, 110 ℃ of insulations 1 hour.Put into high temperature sintering furnace after drying is good and carry out sintering, 800 ℃ of sintering temperatures are incubated 2 hours.At last circle ring column is bonded on the metal axostylus axostyle circle mill CBN emery wheel in making.
This prescription emery wheel adds the AlN abrasive material of larger proportion, and the heat conduction is fast, is applicable to that the workpiece contact area is big, and caloric value is big, and cooling condition is poor, and workpiece easily produces the high-speed grinding of thermal deformation.
Embodiment 2:
Emery wheel is formed: abrasive material 70%, bond 26%, dextrine powder 2%, methocel solution 2%.
Abrasive material proportioning wherein: CBN abrasive material 90%, AlN abrasive material 10%, granularity is 140/170.
Bond adopts 270 purpose microcrystalline glass powders, and its proportioning is as follows: SiO 2: 35%, Al 2O 3: 25%, B 2O 3: 19%, Na 2O:10%, K 2O:5%, LiF:6%
Elder generation carries out abrasive particle wetting with methocel solution, add bond, dextrine powder then, fully mixes more than 30 minutes, crosses 60 mesh sieves, makes the abrasive wheel forming material.The abrasive wheel forming material is put into mould inner pressure make fritter circular arc thin slice.After the air dry 24 hours, put into the drying box drying, 110 ℃ of insulations 1 hour.Put into high temperature sintering furnace after drying is good and carry out sintering, 820 ℃ of sintering temperatures are incubated 2 hours.The arc wheel thin slice that bakes is repaired, cleaned, and being bonded in diameter at last is on the vertical circumferential limit of 300mm disc metallic matrix, is made into the peripheral milling emery wheel.
This prescription emery wheel has reduced the content of AlN abrasive material, is applicable to that grinding speed is big, and bite is many, the high-speed grinding that cooling condition is good.
Above-described only is preferred embodiment of the present invention.Should be understood that for the person of ordinary skill of the art, under technology enlightenment provided by the invention, can also make other improvement, for example, can in emery wheel, add an amount of diamond, Al 2O 3Or hard particles such as SiC improves the overall performance of emery wheel as the part substitute of CBN and AlN, like thatly also should be considered as protection scope of the present invention.
