| titleOfInvention | Polyvinyl acetal resin grinding wheel and production method thereof |
| abstract | The invention discloses a polyvinyl acetal resin grinding wheel and a production method thereof. The polyvinyl acetal resin grinding wheel comprises the following materials in weight by parts: 50-60 parts of CBN abrasives, 5-10 parts of zirconia corundum abrasives, 5-10 parts of silicon powders, 5-15 parts of polyvinyl acetal resin powders, 2-6 parts of furfural, 1-2 parts of trioctyl trimellitate, 5-10 parts of cryolite, 5-10 parts of bauxite, 2-5 parts of nanometer siliceous shale powders and 2-5 parts of tool steel powders. The binder polyvinyl acetal resin used by the invention has high mechanical strength and good heat resistance, and the durability of the prepared resin grinding wheel is greatly improved. According to the invention, ceramic materials are added into a filer, thus the polyvinyl acetal resin grinding wheel has good bonding performance, the abrasives do not easily fall off, the heat resistance and the hardness of the resin grinding wheel are improved, cracks formed by rigid grinding are reduced, and the service efficiency and the service life of the resin grinding wheel are improved; and in addition, as the tool steel powders are added, thus the heat dissipation is fast to be beneficial for fast dissipating a large number of head emitted during cutting of the grinding wheel the role of reducing the cutting temperature is played. |
