该磨床由洛阳轴承研究所和上海市机配公司磨床设计组共同设计,上滚厂机修车间制造。目前,已有两台正式投入生产,生产效率比原来的内圆磨床提高3～4倍,质量稳定,达到国内先进水平。例如,粗磨32312外圈滚道(φ130毫米),班产1500只,生产效率为原来的3～4倍,大批生产时质量稳定。机床特点如下:1.采用高速磨削,砂线轮速度为60 The grinding machine by the Luoyang Bearing Institute and the Shanghai Machine with the company’s grinding machine design team co-design, manufacturing plant on the rolling shop. At present, there are two formally put into production, production efficiency than the original internal grinder to improve 3 to 4 times the quality of stability, reaching the advanced level. For example, Roughing 32312 outer ring raceway (φ130 mm), produce 1500 classes, the production efficiency of the original 3 to 4 times, mass production, quality and stability. Machine features are as follows: 1. Using high-speed grinding, sand wheel speed of 60
