一、前言遵照伟大领袖毛主席关于“中国人民有志气,有能力,一定要在不远的将来,赶上和超过世界先进水平”的教导,为了发展加工直径在20毫米以下的内螺纹磨床新品种,填补我国小直径内螺纹磨床产品的空白,汉江机床厂与陕西机械学院合作,对S764型螺纹磨床的主要部件——高速内螺纹磨具共同进行了研制。在毛主席的革命路线指引下,我们在试验研究工作当中发挥了两个“三结合”的作用,克服了一系列的困难,目前已试制出转速60,000转/分和100,000转/分的两种液压透平式磨具;与此同时亦研制出测速及测功率的相应装置。在工作中曾得到广州机床研
I. Introduction According to the guidance of Chairman Mao, the great leader, on “the Chinese people have ambition and ability, we must catch up with and surpass the advanced world level in the near future”. In order to develop a new type of internal thread grinder with a diameter of 20 mm or less Varieties, to fill the gap of small diameter internal thread grinder products in China, Hanjiang Machine Tool Works and Shaanxi Institute of Mechanical cooperation, the main components of S764-type thread grinder - high-speed internal thread grinding jointly developed. Guided by Chairman Mao’s revolutionary line, we have played a two “three-in-one” role in experimental research and have overcome a series of difficulties. We have already tried two types of vehicles at speeds of 60,000 rpm and 100,000 rpm Hydraulic turbine abrasive; at the same time also developed a speed and power measurement of the corresponding device.
