摘要
Abstract
To improve the machining effect of cemented carbide ball valves,pore-forming agents were introduced into resin diamond wheels.The mechanical properties,microstructures,and grinding performances of the wheels were ana-lyzed,and the effects of hollow glass ball pore-forming agent and plastic ball pore-forming agent on the performances of resin diamond wheels were studied.The results show that the bending strength of the grinding wheel decreases gradu-ally with the increase in the content of pore-forming agent,and the influence of the two pore-forming agents on bending strength is basically the same.The hardness of the grinding wheel also decreases with the increase in pore-forming agent content,but the influence of the hollow glass ball pore-forming agent on the hardness of the grinding wheel is signific-antly greater than that of the plastic ball.The addition of pore-forming agent significantly improves the sharpness of the grinding wheel.The comprehensive performance of the grinding wheels is best when the volume fraction of hollow glass balls is 15％and the volume fraction of plastic balls is 20％,but the latter has better overall performance than the former.关键词
