改善磨具的使用性能是磨削过程中保证加工表面质量,提高劳动生产率的有效途径之一。为了提高砂轮的磨削性能,通常在砂轮的孔隙中,填注各种化学表面活化剂。可将浸渍液体用各种方法注入到多孔的磨具中去,例如,可用真空加压,超声波振荡,毛细管自动吸升等方法。这类方法的缺点是:在磨具使用前,需要多增添一道中间浸渍工序,要增加专 To improve the serviceability of the abrasive is one of the effective ways to ensure the quality of the machined surface and improve the labor productivity during the grinding process. In order to improve the grinding performance of the grinding wheel, various chemical surfactants are usually filled in the pores of the grinding wheel. The impregnating liquid can be injected into the porous abrasive by various methods. For example, the impregnating liquid can be vacuum-pressurized, ultrasonicated, or capped automatically. The disadvantage of this method is: Before the use of abrasive tools, need to add an intermediate impregnation process, to increase the special
