Abstract
The invention discloses a chrome corundum resin grinding wheel and a preparation method of the chrome corundum resin grinding wheel. The chrome corundum resin grinding wheel is prepared from the following components by weight, 50-60 parts of chrome corundum grinding material, 5-10 parts of white corundum grinding material, 5-10 parts of silicon carbide powder, 5-15 parts of phenolic resin powder, 2-6 parts of phenolic resin liquid, 1-2 parts of glycerol glycerate, 5-10 parts of nano blanc fixe, 5-10 parts of attapulgite, 2-5 parts of trioctyl trimellitate and 2-5 parts of copper powder. According to the chrome corundum resin grinding wheel, as the ceramic material is added into padding, the adhesive property is good, the grinding materials hardly fall off, the heat resistance and hardness of the resin grinding wheel are improved, cracks formed by rigid grinding are reduced, and the use efficiency and service life of the resin grinding wheel are improved further; in addition, as the copper power is added, fast heat dissipation effect is achieved, a great deal of heat generated in the cutting process of the grinding wheel can be dissipated quickly, and the effect of lowering cutting temperature is lowered.
Description
Technical field
The present invention relates to a kind of pink fused alumina resin wheel and preparation method thereof, belong to the grinding tool processing technique field.
Background technology
Emery wheel is topmost one type of grinding tool in the grinding.Emery wheel is in abrasive material, to add bond, the porous body of processing through pressed compact, drying and roasting.Emery wheel is a kind of that consumption is maximum in the grinding tool, use face is the widest, rotates at a high speed during use, can roughly grind the cylindrical of metal or non-metal workpiece, interior circle, plane and various profiles etc., half correct grinding and correct grinding and fluting and cut-out etc.Material in order to bonded abrasive in the emery wheel is claimed bond, intensity, impact resistance, hear resistance and the resistance to corrosion of the performance decision emery wheel of bond.At present bond mainly is divided into four kinds on pottery, resin, rubber and metal, and wherein resinoid bond intensity is high, elasticity is big, shock-resistant, is applicable to v>high-speed grinding of 50m/s, can be made into disc wheel, be used for slot grinding, cutting etc.Be referred to as resin wheel with resin as the emery wheel of bond.
Resin wheel divides by abrasive material and generally is divided into ordinary resin emery wheel and superhard resin wheel.The ordinary resin emery wheel is to be the emery wheel of main grinding composition with conventional abrasive materials such as pink fused alumina, pink fused alumina, carborundum, and superhard resin wheel is to be the emery wheel of main grinding composition with diamond or CBN.Resin wheel has that grinding force is little, grinding temperature is low, self-sharpening is good, the grinding efficiency advantages of higher, is widely used in the grinding of hard brittle materials such as carbide alloy, pottery, glass.We know; Up to now the rose grain ratio of in resin wheel, participating in ablation only has an appointment 10%; Most of rose grain is because of relatively poor with its adhesion; In grinding process, be heated, perhaps receive the influence of external force and too early coming off, thereby restricted the service efficiency and the life-span of resin wheel to a great extent.
Summary of the invention
The invention provides a kind of pink fused alumina resin wheel and preparation method thereof, in filler, added ceramic material, its adhesive property is good, makes the abrasive material difficult drop-off, and has improved the hear resistance and the hardness of resin wheel, reduces the crackle that the rigidity grinding forms.
