我车间每年生产各种规格活塞环几万件。为解决手工消除活塞环毛刺浪费人力与工时,一九七三年九月,在车间党支部的领导下,充分发挥“三结合”作用,大搞技术革新,群策群力,自己动手,制成活塞环半自动倒角机。经一年多来的生产使用证明,活塞环半自动倒角机运转可靠,调节自如,加工质量良好,每小时平均倒角外径为70～250毫米的活塞环780个,提高生产效率12倍,每年可为国家节省价值800多元的砂纸。
I workshop every year the production of various specifications piston ring tens of thousands. In September 1973, under the leadership of the party branch of the workshop, the “triple combination” function was given full play to technical renovation and work together to create a piston ring Semi-automatic chamfering machine. After more than a year of production and use of proven, piston ring semi-automatic chamfering machine running reliably, easily adjusted, the processing quality is good, the average chamfering hourly diameter of 70 to 250 mm piston ring 780, improve production efficiency of 12 times, Annual savings of more than 800 yuan for the country’s sandpaper.
