上海第二机床厂针对本厂主导产品“C6150型普通车床”自行设计,制造了一台组合式成型导轨磨床,用于床身导轨面的精加工,使六个导轨表面一次成型磨出。该机床的工作台采用液压传动,进给量可以无级调速,辅以静液压导轨润滑。行程速度v_(粗磨)=17～18公尺/分;v_(精磨)=2公尺分/左右。本机床加工床身精度: 直线性:1米0.015毫米,扭曲度:1米0.01毫米。加工效率: 加工2米床身约2小时,比刮研提高效率10多倍,比用端磨提高效率4～5倍。以下介绍该机床的砂轮主轴与修整器结构。砂轮主轴结构参见图1。成型砂轮根据工件的形状、尺寸由几个单片砂轮拼合而成,砂轮
Shanghai No.2 Machine Tool Factory designed and manufactured a combined-type guide rail grinder designed for the factory’s leading product “C6150 Lathe”, which is used for the finishing of the guide rail surface of the bed so that the surfaces of the six guide rails are formed once. The machine table hydraulic transmission, the feed rate can be stepless speed, supplemented by hydrostatic rail lubrication. Travel speed v_ (rough grinding) = 17 to 18 m / min; v_ (fine grinding) = 2 m / min. The machine tool bed precision: linearity: 1 m 0.015 mm, twist: 1 m 0.01 mm. Processing efficiency: Processing 2 meters bed about 2 hours, than scraping to improve the efficiency of 10 times more efficient than the end mill to improve efficiency 4 to 5 times. The following describes the machine wheel spindle and dresser structure. Wheel spindle structure see Figure 1. Shaping wheel according to the shape of the workpiece, the size of a few monolithic wheel made of mosaic, wheel
