M 120 W万能外圆磨床是一种结构简单、使用方便、通用性强的内外圆磨床。随着社会主义革命和建设的需要,其产品数量逐年上升,为了进一步提高劳动生产率,解决机加工不足的困难,在党的正确领导下和工人师傅的积极支持下,我们从1967年起对各种类型的塑料零件和在机床上的应用,作了试验研究和推广。到目前为止,在M 120 W磨床上应用的塑料零
The M 120 W universal cylindrical grinding machine is a kind of internal and external cylindrical grinding machine with simple structure, convenient use and strong versatility. With the needs of the socialist revolution and construction, the number of its products has increased year by year. To further increase labor productivity and resolve the inadequacy of machining, under the correct leadership of the Party and the active support of the workers’ masters, we have been working on each one since 1967. A variety of types of plastic parts and applications on machine tools have been experimentally studied and promoted. So far, zero plastics applied on M 120 W grinders
