在毛主席光辉的“五·七”指示指引下,我们化机七三级工农兵学员和教师,到宝鸡永红起重运输机械厂实行开门办学,厂校结合共同完成了曲轴铣削工具的传动和刀具设计与制造工作。 一、用途及设计要求 1、用途: 该厂是一个生产多种产品的中型机械厂,所生产氮氢机的曲轴批量不大,过去是在C650车床上进行加工生产。由于这种工艺劳动强度大,效率低,影响了主机的生产,不能适应于小化肥生产的迅猛发展,我们和工人师付一起分析了各个生产环节,对曲轴
Guided by Chairman Mao’s glorious “May 7” directive, we organized the workers, peasants, soldiers and teachers at the Seventy-three level of workers and peasants in Baoji to open their doors to Baoji Yonghong Crane Transport Factory and completed the drive of crankshaft milling tools And tool design and manufacturing. First, the use and design requirements 1, use: The plant is a medium-sized machinery factory producing a variety of products, the production of nitrogen and hydrogen crankshaft volume is not large, the past is in the C650 lathe for processing production. Because of this labor-intensive process, low efficiency, affecting the host production, can not adapt to the rapid development of small fertilizer production, we and workers to pay together to analyze the various production processes, the crankshaft
