过去我车间轴承毛坯的生产工艺,是比较落后的,不能适应轴承生产飞速发展的需要。自从一九七二年六月在济南召开全国轴承毛坯工艺经验交流会以来,我车间在厂党委与车间党支部的领导下,广大革命职工,以大庆为榜样,为改变我车间的落后面貌.先后在苏315吨压力机,J37—200吨压力机,J37—3150吨压力机上进行了塔型试验. In the past I workshop bearing rough production process is relatively backward, can not adapt to the rapid development of bearing the needs of production. Since the holding of the national bearing blank technology experience exchange meeting in Jinan in June 1972, under the leadership of the factory party committee and workshop party branch, the majority of revolutionary workers take the example of Daqing to change the backwardness of our workshop. Su-315 tons in the press, J37-200 tons of presses, J37-3150 tons of presses on the tower test.
