Problems solved by technology
The grinding wheel in the prior art has the following disadvantages: its production cost is relatively high, and it uses colored precious metal powder, and the glaze powder ground out cannot be recycled well due to the presence of metal powder. The bonding agent of the trimming wheel is also relatively wasteful of resources, which makes the user satisfaction not high
The sintering temperature of the outer grinding wheel is 630-710°C, and the hot pressing temperature of the inner grinding wheel is 175-185°C, which has the disadvantage of high energy consumption

Abstract
The invention discloses a dry grinding wheel. The dry grinding wheel comprises a substrate and a grinding head arranged on the substrate. The grinding head is prepared from, by weight, 130 parts to 200 parts of diamond, 100 parts to 130 parts of silicon carbide, 60 parts to 100 parts of polyvinyl chloride resin powder, 5 parts to 10 parts of coupling agents, 200 parts of silicon carbide micro powder, 10 parts to 20 parts of anti-abrasion agents, and 60 parts to 100 parts of polyvinyl alcohol gelatine powder. The invention discloses a manufacturing method of the dry grinding wheel. The raw materials are weighed according to the formula of the grinding head, then, an evenly mixed mixture is obtained through the mixing technology, and finally the dry grinding wheel is obtained through the forming technology. The dry grinding wheel has the advantages that the materials are easy to obtain, grinding sharpness and hardness performance of a grinding wheel matrix are good, and the service life is long. The manufacturing method has the advantages of being low in sintering temperature, low in manufacturing cost and capable of achieving energy conservation and environmental protection.
Description
technical field [0001] The invention relates to a grinding wheel and a manufacturing method thereof, in particular to a dry grinding wheel and a manufacturing method thereof, which are suitable for glazed dry-type edging machines. Background technique [0002] At present, when the common dry grinding wheel grinds glazed tiles, two types of dry metal bonded grinding wheel and polyimide resin bonded dry trimming wheel are used in combination. In addition, the Chinese patent application number is The invention patent of "200610035898.1" discloses a grinding wheel and its manufacturing method. The formula weight ratio of the inner grinding wheel is: diamond 90-110 g, green silicon carbide 45-55 g, coupling agent 45-55 g, modified Phenolic resin powder 90-110 g, filler: green silicon carbide powder 90-110 g, alloy powder 162-196 g, ZnO 18-22 g, cr 2 o 3 32-48g. The manufacturing method is to press a ring of resin bonded diamond working layer on the inner layer of the metal ...
