混合磨料珩磨油石的磨削性能研究

本文介绍了几种常用磨料(刚玉系列和碳化硅系列磨料)的磨削性能,设计了十几种按不同比例混合的多种磨料珩磨油石,对45#钢、不锈钢和钛合金等金属材料进行了珩磨对比试验,通过试验结果分析得出:①珩磨具有一定硬度的钢类零件,选用SA(90%)和GC(10%)的混合珩磨油石,磨削效果好,磨削比高,并且没有粘附现象,能充分发挥两种磨粒的磨削性能;②珩磨奥氏体不锈钢(1Cr18N i9Ti),选用WA(90%)和GC(10%)的混合珩磨油石,既能提高磨削比,又能减小油石的粘附现象;③对于钛合金材料,选用GC(70%)和SA(30%)的混合珩磨油石,磨削效率较高,油石粘附较少,并不易破碎,具有较好的磨削效果;④混合磨料珩磨油石在磨削一些金属材料时具有比单一磨料油石更好的磨削性能。

Study on grinding performance of mixd-abrasive grits honing stones

This article introduces the properties of several kinds of abrasives including corundum(series) and silicon-carbide series,and presents the design of several mixture-abrasive honing stones with different abrasives in different proportions.Several workpieces of typical metal materials were honed in the contrast experiments.Through analyzing the experiment results,it can be drawn that(1) for the steel workpiece with certain hardness,the mixture-abrasive honing stones with SA(90%) and GC(10%)are recommended,which have higher grinding efficiency,and almost no loading during honing;(2) For stainless steel,1Cr18Ni9Ti,selecting the mixture-abrasive honing stones with WA(90%)and GC(10%)ether can raise the material removal and reduce the tendency of loading.(3) For titanium alloys,the mixture-abrasive honing stone with GC(70%)and SA(10%)is not ease to break down,and has higher grinding efficiency, little tendency of loading better grinding effect.(4) the mixd-abrasive honing stones have better honing performances than single abrasive honing stones when grinding some metals.
