测绘仪器和计量仪器中的分度元件,多数是在平面、柱面、锥形面等几何形体上附着分度标记而构成。由于目前工艺设备的现状,除平面分度元件广泛采用照相底版复制加工方式外,余者大都依靠专用机床刻制。机床刻制加工在大批量生产时效率低,成本高,特别是当元件上分度标记间距值分布不 Mapping instruments and measuring instruments in the indexing components, most of the plane, cylinder, cone and other geometric body attached to the graduation marks and composition. Due to the current status of the process equipment, in addition to flat-scale components widely used photographic plate copy processing methods, the rest mostly rely on dedicated machine engraving. Engraving machine tools in high-volume production of low efficiency, high cost, especially when the components on the index mark spacing value distribution
