在外地经验的启发下,通过三结合的方式,试验得出几种不同类型车刀的小月牙洼几何参数,对比了几种研磨剂配方,试用了几种研磨方法。根据上述对比,可以推荐利用磨削下来的碳化硅砂轮粉末作为研磨剂;可以根据不同使用条件采取几种不同的经济、方便的研磨方法。最后,分析了此种断屑方法的优点以及目前存在的问题。 Inspired by the experience of other countries, the geometrical parameters of the small crespus depression of several types of turning tools were obtained through three combined methods. Several grinding formulations were compared and several grinding methods were tested. According to the above comparison, it can be recommended to use the grinding of the silicon carbide grinding wheel powder as an abrasive; can be used according to different conditions to take several different economical and convenient grinding method. Finally, the advantages of this chip breaking method and the existing problems are analyzed.
