我厂机械一车间继1977年建成一条 L207E型柴油机气缸套内孔加工自动线(见本刊1978年第3期)后,于1978年又建成了一条 L207E型柴油机气缸套外圆加工自动线。这条自动线经过半年时间的生产实践,证明性能良好、工作稳定、加工质量可靠,符合设计要求,使气缸套外圆加工过程中的粗车外圆、半精车外圆、切密封槽、车过渡圆弧,以及定位、夹紧、排屑、冷却和工件的上下、输送等工序均实现 In 1977, our factory built a L207E diesel engine cylinder line bore automatic processing line (see article published in 1978 No. 3), in 1978 and built a L207E diesel engine cylinder liner cylindrical automatic processing line. This automatic line after six months of production practice, proven good performance, stable work, processing quality and meet the design requirements, so that cylindrical outer cylinder rough cylinder machining process, semi-fine car outside the circle, cut sealing slot, car Transition arc, and positioning, clamping, chip removal, cooling and workpiece up and down, conveying and other processes are achieved
