为了适应新国标对轴承零件滚道尺寸(±3s)的要求,将单点倾斜式内圈滚道主动测量仪用于3MZ2120磨床上,使内滚道直径尺寸分散度减小到6.5μm。文中介绍了仪器的结构和工作原理。附图3幅。
In order to meet the new national standard of bearing parts raceway size (± 3s) requirements, the single point inclined inner raceway initiative measuring instrument used in 3MZ2120 grinder, so that the inner raceway diameter size dispersion to 6.5μm. The article describes the structure and working principle of the instrument. Figure 3 Figure.
