缓进给磨削是在普通往复磨削的基础上发展起来的。从50年代缓进给磨削加工工艺方法问世以来,在世界各国得到越来越广泛的应用。以其主要生产厂联邦德国ELB磨床厂情况来看,从1952年研制到1979年为止,共生产缓进给磨床3620台,由此可见生产应用范围之广。我国从70年代后期,首先在我厂应用这项新工艺。开始用于磨削2.3 Slow feed to the grinding is developed on the basis of ordinary reciprocating grinding. From the 50’s to slow grinding technology to the advent of the world has been more widely used in all countries. The main production plant in Germany, Germany ELB grinder plant situation, from the development in 1952 to 1979 so far, a total of 3,600 sets to slow to the grinder, we can see a wide range of production applications. From the late 1970s, our country first applied this new technology in our factory. Begins to grind 2.3
