奥本金属多面棱体是一种高精度标准器具，它主要用于检定光学分度头.分度台.测角仪等圆分度仪器的分度误差，在高精度的机械加工或测量中也可以作为角度的定位基准。它分为偶数面和奇数面两种，前者的工作角为整度数，他用于检定圆分度器具轴系的大周期误差，还可以进行对径测量，而后者的工件角为非整度数，它可综合检定圆分度器具轴系的大周期误差和测微器的小周期误差，能较正确地确定圆分度器具的不确定度。
  AUBAT metal Polyhedral Prism is a high-precision standard equipment, it is mainly used for testing optical indexing head. Indexing Table. Goniometer and other round indexing device graduation error, high-precision machining or measurement can be As a point of reference for positioning. It is pided into two kinds of even face and odd face, the former working angle for the degree of integer, he used to test the large cycle of circular indexing device axis error, but also for the diameter measurement, while the latter part of the workpiece angle non-integral number , Which can comprehensively test the large cycle error of the circular indexing tool shafting and the small period error of the micrometer to more accurately determine the uncertainty of the circular indexing device.
