【摘要】 本文根据磨削液的作用机理及钛合金的磨削特点,对高效钛合金磨削液具备的主要特性作了分析。通过对新研制的磨削液与两种常用磨削液的对比试验,证实新研制的磨削液具有磨削比高,砂轮损耗低,磨削力小,磨削温度低,砂轮粘附少,工件表面粗糙度低,变形小,无烧伤等优点。运用金相显微摄影及扫描电镜等手段,对磨削中砂轮表面的粘附作了定点跟踪拍摄和砂轮粘附面积图象分析,结果证明新研制的磨削液对减少砂轮粘附有显著的效果。更多还原

【Abstract】 The paper analyzed the chief characteristics of the high-efficiency fluids for grinding titanium alloys. By the contrast experiments about the grinding properties of the newly developed fluids compared with that of the two kinds of common ones in grinding titanium alloys, it is proved that new fluids are possessed of following advantages, such as higher grinding ratio, less wheel wear, smaller grinding force, lower grinding temperature, less wheel adhesion, smaller roughness and deformation of workpiece and little surface burn etc. By means of the metallograph and SEM the fixed-point track shooting and the microstructure image analysis are made on the adhesive formation on wheel surface in grinding. The results show that the newly developed fluids are of remarkble efficiency in reducing wheel adhesion.更多还原
