Abstract

The invention discloses a preparation method of a glass grinding disc. The preparation method comprises the following steps of: 1, preparing slurry; 2, forming a blank body of the grinding disc; 3, sintering; 4, machining. The method has the advantages that: the slurry for forming the grinding disc is obtained by using a chemical copolymerization sedimentation method, the grinding disc has a uniform and fine structure, can achieve highly uniform distribution of CeO2 abrasive in the glass grinding disc, and a glass device grinded by the glass grinding disc has uniform and fine grinding grains on the surface, so that the phenomenon of coarse scratches does not exist; the bonding agent of the grinding disc for bonding the CeO2 abrasive is an AlPO4. nH2O inorganic cementing material, the elastic modulus of the bonding agent is larger than that of a resin material, the elastic deformation amount of the glass grinding disc is small in the process of grinding glass, the straightness error ofthe grinded glass device is less than 3 micrometers / 25 millimeters, the processing requirements of high-precision glass optical devices can be well met.

Description

【Technical field】 [0001] The invention relates to the technical field of abrasive tool preparation, in particular to a method for preparing a glass grinding disc that uses aluminum phosphate gelling material to bond cerium oxide abrasives. 【Background technique】 [0002] CeO 2 Grinding disc for grinding process. The processing method has the advantages of high grinding efficiency and good surface finish of the processed workpiece. At present, the preparation method of grinding discs for glass polishing is to use CeO as abrasive 2 After the powder is mixed with the resin, the resin solidifies under certain conditions to form a resin grinding disc with a certain shape and strength. Commonly used resins include phenolic resin, unsaturated polyester resin, polyamide resin and epoxy resin. According to the shape of the resin, CeO 2 The molding and curing process of the grinding disc is also different. When the resin is liquid, the grinding disc is prepared by pouring and cur...
