螺纹磨床是目前机器制造行业制造圆柱螺纹、圆锥管牙螺纹、梯形螺纹以及絲锥板牙和其他螺纹量具等所迫切需要的。一种机床。历年来,我厂生产的产品多为石油钻探机械用的管件、连接部件和阀门等零部件,产量多,螺纹尺寸大,精度要求高,而我厂螺纹量规的制造远远不能满足生产需要。因此,车间老工人发扬自力更生、奋发图强的革命精神,将普通车床改装为螺纹磨床,并于1963年改装成功。普通螺纹量规原来是采用40号铬钢,经调质热处理后车削而成,精度不易掌握,光洁度也达不到要求,使用寿命低。现用普通车床改装的螺纹磨床磨削,使用寿命可提高十倍,齿形光洁度达到▽▽▽▽10,而改
Thread grinder is currently the manufacturing industry manufacturing cylindrical thread, cone thread, trapezoidal thread and taping die and other thread gauge urgent need. A machine tool. Over the years, I plant products mostly oil drilling machinery used pipe fittings, connecting parts and valves and other parts, production and more thread size, high precision, and I plant thread gauge manufacturing far can not meet the production needs. Therefore, the workshop workers carry forward the revolutionary spirit of self-reliance and work hard to transform the ordinary lathe into a thread grinder, and converted in 1963 success. Ordinary thread gauge is the original use of 40 chrome steel, after quenching and tempering heat treatment made of precision is not easy to grasp, the finish does not meet the requirements, low service life. Now ordinary lathe modified thread grinder grinding, the service life can be increased tenfold, tooth profile finish ▽ ▽ ▽ ▽ 10, and change
