以磨代铣是目前磨削加工发展的趋势之一。以磨代铣加工钻头沟槽,是工具行业生产钻头,由铣加工改为磨削加工,改变部分工具生产落后状态采用的一项新工艺、新技术。目前国外如日本、美国、西德等国家,已广泛采用这种工艺技术。我国现已应用此项新技术。关中工具厂为了实现这一新工艺、新技术,在一九七二年十月份,要求我厂试制以磨代铣的新型磨具。我们遵照毛主席关于“我们必须打破常规,尽量采用先进技术,在一个不太长的历 Milling milling is the current development of grinding one of the trends. Milling milling cutter bits and grooves to wear, the tool industry is the production of drill bits, from milling to grinding, changing the backward production of some tools used in a new technology, new technology. At present, foreign countries such as Japan, the United States, West Germany and other countries have adopted this technology widely. China has now applied this new technology. Guanzhong Tool Factory In order to realize this new process and new technology, in October 1972, we asked our factory to try out a new type of abrasive tool that was designed to mill for milling. We follow Chairman Mao’s statement that "we must break the routine, try to adopt advanced technology, in a not too long calendar
