本文在缓进磨削条件下,用氧化铝和碳化硅砂轮,对TC4钛合金进行磨削试验,并用正交试验方法,根据正常磨削长度、工件表面光洁度、磨削比和比磨削能,综合选出了最佳工艺条件,导出了经验公式。试验论证了缓进磨削是磨削钛合金的有效方法和目前达到的最好水平。 In this paper, the conditions of slow grinding, the use of alumina and silicon carbide grinding wheel, TC4 titanium alloy grinding test and orthogonal test method, according to the normal grinding length, the workpiece surface finish, grinding ratio and specific grinding energy , The best selected process conditions, derived empirical formula. The experiment demonstrated that slow grinding is an effective method to grind titanium alloy and the best level achieved at present.
