我厂在上海钢球厂的积极支持和配合下,设计,制造成功了3MA4750钢球研磨机。为轴承行业提供了新设备.解放以来,我国的滚动轴承行业从无到有,从只能生产一般精度等级的轴承到生产超精密级轴承,发展速度是惊人的。目前已基本上满足国内主机的配套需要。但随着四个现代化建设的深入发展,同国外先进的工业化国家水平相比,我国的滚动轴承在产品
I plant in Shanghai Ball Factory’s active support and cooperation, the design, manufacture successful 3MA4750 ball grinding machine. For the bearing industry has provided new equipment.From the liberation, China’s rolling bearing industry from scratch, only from the general level of precision bearings to the production of ultra-precision bearings, the development rate is staggering. At present, it basically meets the matching needs of domestic hosts. However, with the further development of the four modernizations, compared with the advanced industrialized countries in the world, the rolling bearings in our country
