Ceramic bonding agent large-diameter grinding wheel manufacturing method

Abstract

The invention discloses a ceramic bonding agent large-diameter grinding wheel manufacturing method and relates to the technical field of grinding wheel manufacturing. The ceramic bonding agent large-diameter grinding wheel manufacturing method comprises the following technological processes of mixing, wherein an abrasive, a bonding agent, an adhesive and a wetting agent are accurately weighed according to formula weight parts, the abrasive is added into the wetting agent first, the wetting agent is then added, the adhesive and the bonding agent are added finally, the mixing time is prolonged,and a clean pot needs to be opened to uniformly mix the bonding agent with the abrasive; and forming, wherein a formed material well mixed in the material mixing process is placed in a phi 1712mm grinding sleeve, a 2000 ton pressing machine is used for pressing to ensure the shaping thickness. According to the ceramic bonding agent large-diameter grinding wheel manufacturing method, the problemof cracking during firing of a large-size grinding wheel is controlled in the drying process, grinding wheel permeability is solved in the roasting process, cooling stress is eliminated, the finishedproduct precision of the grinding wheel is improved in the processing process, the forming rate of the phi 1700 grinding wheel is increased, the problem that the existing phi 1700 grinding wheel is difficult to form is solved, and the yield is improved.

Description

Technical field [0001] The invention belongs to the technical field of grinding wheel manufacturing, and particularly relates to a method for manufacturing a large-diameter grinding wheel with a ceramic bond. Background technique [0002] The known domestic use of the largest diameter grinding wheel Φ1600mm is suitable for the grinding of compressor crankshafts of large-scale chemical projects and the grinding of crankshafts of large-scale marine diesel engines. With the rapid development of the crankshaft industry, the grinding technology requirements for large crankshafts are getting higher and higher. The radius of gyration of large crankshafts is determined, and continuous use reduces the frequency of grinding wheels. Therefore, Φ1600mm grinding wheels can no longer meet the technical requirements of large crankshaft grinding, and it is difficult to produce Φ1700mm grinding wheels. Large, the shrinkage rate of the grinding wheel is 50% larger than that of the Φ1100 grinding w...
