我厂先进生产者,中压车间车工殷宝玉同志,在车间技术员史今生同志的帮助下,创造了一种车床万能卡具和套料车刀,用来加工法兰类工件,使生产效率提高3～34倍。过去殷宝玉同志在加工挡油板(如图1乙)时,是先把方形钢板(如图1甲)用四爪卡盘夹住,车出外圆,再用三爪卡盘撑住内圆,车出外圆,然后划线钻孔。这样一个一个来加工,生产效率很低,而且容易出废品。经过他们共同研 The advanced producer of our factory, Comrade Yin Baoyu of the medium-pressure workshop mechanic, with the help of Shi Jinsheng, a technician in the workshop, has created a universal lathe lathe and nesting turning tool for processing the flange type workpieces so as to improve the production efficiency 3 to 34 times. In the past, Comrade Yin Baoyu was processing oil deflector (Figure 1 B), the first square plate (Figure 1 A) with a four-jaw chuck, the car out of the circle, and then use the three-jaw chuck to hold the inner circle , Car out of the circle, and then crossed the hole. This one by one processing, production efficiency is very low, but also easy to waste. After their common research
