随着仪器、机器制度事业的迅速发展,近年来对精密主轴不圆度的检测要求也愈增。因此,发展不圆度的各种测量方法与仪器具有重要意义。圆度仪就是在这种情况下生产出来的一种较好的仪器。但是,由于圆度仪制造工艺复杂,价值昂贵,不易多得,因此,研究轴颈不圆度的其它测量方法仍具有现实意义。在这方面,最常用的是V形块法。它具有测量精度高,不需要与任何基准 With the rapid development of instruments and machine system business, testing requirements for the precision spindle non-roundness have also increased in recent years. Therefore, the development of non-roundness of the various measurement methods and instruments of great significance. Roundness meter is a better instrument produced in this case. However, due to the complexity of the circularity meter manufacturing process, the value is expensive and not easy to obtain, so it is of great significance to study other measuring methods of journal out-of-roundness. In this regard, the most common is the V-block method. It has high measurement accuracy and does not require any benchmarking
