中间相炭微球对多层钎焊金刚石砂轮电解修整磨削性能的影响
Influences of MCMBs on Electrolytic Dressing and Grinding Performances of Multi-layer Brazed Diamond Grinding Wheels
摘要
Abstract
The oxide film of large particle size multi-layer brazed diamond grinding wheel had poor quality and insufficient thickness during electrolytic dressing,which led to poor grinding perform-ances.MCMB were added to the abrasive layers to improve this situation.The effects of different MC-MB contents on the performances of the grinding wheel and the electrolytic dressing grinding charac-teristics were investigated.The results show that MCMB may significantly improve the electrolytic film-forming ability of the grinding wheel,the maximum thickness of the oxide film is as 104 μm,and the compactness and adhesion are improved.The ground surface morphology of the test groups contai-ning MCMB has higher integrity and fewer fracture pits.Compared with the test groups without MC-MB,the values of surface roughness Ra of the MCMB test groups with a volume fraction of 5％ de-crease by 29.8％ when the workpiece speed is as 40 mm/s and the grinding depth is as 15 μm,and the subsurface damage depth is reduced by 47.9％ when the workpiece speed is as 30 mm/s and the grind-ing depth is as 20 μm.关键词
