随着我国社会主义建设的飞速发展,精密螺纹应用日益增多;用传统的单线磨削螺纹的方法,生产效率低,不能满足生产发展需要。为此,我们改装一台Y7520K螺纹磨床,成功地采用了多线砂轮磨削螺纹的新工艺,部分地取代了车、铣等粗加工工序和半精加工工序,其生产率较过去提高3～5倍。现 With the rapid development of socialist construction in our country, the application of precision thread is increasing day by day. With the traditional single-thread grinding method, the production efficiency is low and can not meet the needs of production development. To this end, we modified a Y7520K thread grinder, the successful use of a multi-line grinding wheel thread new technology, partially replaced car, milling and other rough machining processes and semi-finishing processes, the productivity increase over the past 3 to 5 Times Now
