1、The necessity of the lens electrode coaxality especially the coaxality of the aperture with lens axis is emphasized.
2、In this paper, the method and measures for turnover boring with high coaxality are expounded.
3、With the error judgment of the coaxality and the inspection method of error of the coaxality, the inspector can inspect easily, promptly and accurately if the method is used properly in daily work.
4、This instrument is used for measuring roundness, axis straightness, coaxality and circular run out error of shaft parts.
5、This paper studies concept, calculation and gauge design concerned with coaxality of main spindle hole and camshaft hole and points out some common errors.
6、High-precision horizontal reference and axial reference are established and fixed equal-height supports are used to ensure the reliable coaxality of bar-bar system.
7、The mathematical models of coaxality error by evaluation of the orthogonal least square method and the minimum condition method are presented in this paper.
8、It can measure not only the inner diameter, outer diameter and linearity error, but also the center distance between holes, taper and position errors such as coaxality, verticality, etc.
