在全国“工业学大庆”的高潮中,一个赶超国内外先进水平的群众运动轰轰烈烈地展开。 我们通过学习马列著作和毛主席著作,学习大庆,促进了思想革命化,解放了思想,树立了敢于打破洋框框,敢于发明创造,敢于在钢球加工方面走出自己的道路,敢于赶超国内外先进水平的雄心壮志。 遵照毛主席“要认真总结经验”和“一切产品,不但求数虽多,而且求质量好,耐穿耐用”的伟大教导,为了迅速提高钢球质量,达到和超过世界先进水平,我们狠批了从外国搬来的洋工艺框框,改革了原来的洋设备,使钢球质量普遍得到提高,并使部分钢球达到和超过了国内外先进水平。下面就我们的改革作一介绍。 一、改进工艺提高钢球质量 各种机械工业对球轴承提出了愈来愈高的要求,特别是电机轴承要求噪声很低,所以对钢球的要求也更高了。 通过试验,我们知道球轴承产生噪声的主要原因,是转动套圈（一般是内圈）沟道
In the climax of the “Daqing Industrialization” nationwide, a mass movement to catch up with and surpass advanced levels at home and abroad was vigorously launched. By studying Marxism-Leninism and Chairman Mao’s writings, we have studied Daqing, promoted ideological revolution, liberated our minds, set up the courage to break the yangang frame, dare to invent and dare to go out of our own ways in the sphere processing, dare to catch up with and surpass the domestic and foreign Advanced level of ambition. In line with Chairman Mao’s “serious lessons learned” and “all products, not only seek a few but also good quality, durable wear-resistant” great teaching, in order to rapidly improve the quality of the ball to meet and exceed the world’s advanced level, we severely criticized The foreign technology moved from foreign countries to reform the original foreign equipment, so that generally improve the quality of the ball, and part of the ball reached and surpassed the advanced level at home and abroad. Here’s an introduction to our reform. First, improve the process to improve the quality of the ball Various mechanical industry on ball bearings made higher and higher requirements, especially motor bearings require low noise, so the requirements of the ball is also higher. Through the test, we know that the main reason for the ball bearing noise is rotating the ring (usually the inner ring) channel
