AI Technical Summary

Problems solved by technology

[0004] Commonly used wetting agents for grinding wheels include water glass, dextrin, polyvinyl alcohol, paraffin, etc., but they all have their own shortcomings: water glass has too high viscosity, so its fluidity is poor, and it is easy to react with carbon dioxide in the air and deteriorate; Dextrin has a single function, is expensive, and has poor fluidity; polyvinyl alcohol with a low degree of alcoholysis is too expensive to be suitable for industrial production, and polyvinyl alcohol with a high degree of alcoholysis is insoluble in water, and its viscosity is unstable, making the mixture loose and fluid. ; The compatibility of paraffin wax is poor, and the product is easy to stick when the amount is too much

Description

technical field [0001] The invention relates to the technical field of grinding wheel processing, in particular to a processing technology of a metal bond diamond grinding wheel. Background technique [0002] Diamond grinding wheel is made of diamond abrasive as raw material, and metal powder, resin powder, ceramics and electroplated metal are used as binders respectively. The circular bonded abrasive tool with a through hole in the center is called diamond grinding wheel (alloy grinding wheel). [0003] With the development of modern machining in the direction of high precision, high speed, hard machining, dry machining (no coolant) and cost reduction, quite high requirements are placed on the performance of abrasive tools. Traditional silicon carbide and corundum ordinary abrasive molds can no longer fully meet the current high-speed, high-efficiency and high-precision grinding requirements. Therefore, it is an inevitable development to develop various superhard grinding m...
