在毛主席革命路线指引下,为了适应生产发展需要,不断改革旧工艺,我厂于1973年设计制造了一台精镗摇臂大孔的S_2—100型组合精镗床(图1)。由于实行了工人、干部和技术人员三结合,走“鞍钢宪法”指引的道路,使这台机床在使用中收到了予期的效果,满足了现场生产的要求。下面仅就有关工艺和机床主要部件结构特点作一简单介绍。 Under the guidance of Chairman Mao’s revolutionary line, in order to meet the needs of production and development, and constantly reform the old craft, our factory designed and manufactured a S_2-100 type combined boring machine with fine boring arm and large hole in 1973 (Figure 1). Due to the combination of workers, cadres and technicians, taking the road of “Ansang Steel Constitution” guidelines, this machine has received the expected results in use, to meet the requirements of the production site. The following only on the main components of the technology and machine tool structure for a brief introduction.
