预放管体(零件如图1)的二平行深孔φ30_(+0.05)~(+0.1)的长度与直径之比较大,而且孔的公差、光洁度、相互位置精度要求较高,故加工比较困难。在该零件的加工过程中,以工人为主体的三结合小组的同志们,遵照毛主席“政治工作是一切经济工作的生命线”的伟大教导,克服了深孔加工经验少,条件差等困难,在有关工种的大力协助下,经过群策群力,终于加工出了合格零件。
Pre-release pipe body (parts as shown in Figure 1), the two parallel deep hole φ30 _ (+0.05) ~ (+0.1) the length and diameter of the larger, and the hole tolerances, finish, mutual accuracy requirements are higher, so processing comparison difficult. During the processing of this part, the comrades of the three-in-team with the workers as the main body, following the great teaching of Chairman Mao’s “Political work is the lifeline of all economic work”, overcame the difficulties of deep hole machining with little experience and poor conditions, With the help of the relevant types of work, we have finally worked out qualified parts through concerted efforts.
