Abstract

The invention discloses a formula of a resin grinding wheel angle abrasive disc. The resin grinding wheel angle abrasive disc comprises a coarse material layer, another coarse material layer and a fine material layer which are composited in sequence. Raw materials of the coarse material layers include SG adhesive materials, AZ40 fused alumina zirconia, white corundum, liquid phenolic resin, liquid epoxy resin, 325-400-mesh powdery phenolic resin, 400-600-mesh potassium fluoborate, 600-800-mesh electrolytic copper powder and 600-800-mesh talcum powder. Raw materials of the fine material layer include brown fused alumina, white corundum, liquid phenolic resin, liquid epoxy resin, 325-400-mesh powdery phenolic resin, 400-600-mesh potassium fluoborate and 600-800-mesh talcum powder. The made resin grinding wheel angle abrasive disc is good in hand feeling, free of edge breakage, large in grinding removal quantity, high in grinding efficiency and adaptability and capable of meeting the requirements for rapid coping of tracks and weld joints, and machined workpieces are high in surface precision.

Description

technical field [0001] The invention relates to the technical field of metal grinding tool products, in particular to a formulation of a resin grinding wheel angle grinding disc and a processing method thereof. Background technique [0002] Resin grinding wheel angle grinding discs are widely used in the grinding process of foundry, ship, rail, automobile, building materials and other fields because of their good strength, toughness, self-sharpening, high grinding removal and other characteristics. In recent years, with the rapid development of my country's high-speed railway industry and shipbuilding industry, the demand for high-efficiency and high-precision resin grinding wheel angle grinding discs has been increasing year by year, but the grinding efficiency of domestic angle grinding discs is generally low at present, and grinding removal The amount is small, edge chipping is more common, the grinding feel is poor, and the surface accuracy of the processed workpiece is n...
