一批型号为C136204、每分钟转速达到100,000转和精度等级的“C”级的高速超精级轴承已在我国国营哈尔滨轴承厂诞生.这个工厂原来计划要到196O年才准备试制这种高速超精级轴承,但由于全厂职工在整风运动取得全胜的基础上,解放思想,破除技术迷信、敢想敢干、利用现有设备和生产条件,终于在今年“七一”节前夕试制成功了一批达到国际水平的每分钟100,000转的超精级轴承作为向党生日的光荣献礼.试制出的轴承经过工厂技术领导及有关专家们的测量和检查,证明轴承的所有尺寸公差,精度、表面
A number of models C136204, speed up to 100,000 rpm and the accuracy level of “C” -level high-speed super-precision bearings have been born in China’s state-run Harbin Bearing Factory. The factory was originally planned to 196O years before the trial preparation of this high-speed super But due to the victory of the rectification campaign, all employees of the entire factory emancipated their minds, dispel superstitious ideas, dare to dare to do something, and make use of existing equipment and production conditions to finally make trial on the eve of July 1 this year A group of world-class ultra-fine bearings at 100,000 rpm per minute as a birthday gift to the honor of the trial production of the bearing through the factory technical leadership and the experts of the measurement and inspection to prove that all dimensional tolerances bearings, precision, surface
