一、前言我厂生产的汽车分动器总成和部分变速器零件,其中有几种带台阶的轴类零件和一种带球面的操纵杆,开始都是在一般的普通车床上加工,不仅效率低,劳动强度大,且产品质量也不稳定。广大职工遵照毛主席“自力更生,艰苦奋斗”的教导,大搞技术革命和技术革新活动,先后设计试制了一批CZ20液压仿形车床。通过几年来的使用证明,这种仿形车床的特点是造价低,操作方便,生产效率高,劳动强度低,产品质量稳定,为今后轴类零件加工自动化创造了有利条件。
I. INTRODUCTION The auto transmission assembly and some transmission parts produced by our factory include several types of shaft parts with steps and a joystick with a spherical surface. All of them are processed in the ordinary lathe at the beginning. Not only the efficiency Low, labor-intensive, and product quality is not stable. According to Chairman Mao’s guidance of “self-reliance and hard work”, the majority of workers and staff engaged in technological revolution and technological innovation activities, and successively designed and manufactured a batch of CZ20 hydraulic copying lathe. After several years of use proved that this profiled lathe is characterized by low cost, easy operation, high production efficiency, low labor intensity, product quality and stability for the future axis machining automation has created favorable conditions.
