新天光学仪器厂和德国生产的万能工具显微镜光学分度头 ,它们原理结构基本相同。如果检定中发现示值超差 ,分析其原因主要是度盘紧固螺丝松动 ,引起度盘与轴转动偏心。根据有关资料和通常的调整方法 ,调整起来费时、费事 ,现介绍一种新方法 ,在检定现场调整起来很方便。万能工 Xintian Optical Instrument Factory and the German production of universal tool microscope optical sub-head, the principle of their structure is basically the same. If the check shows that the value of tolerance, analysis of the main reason is that the disc fastening screws loose, causing the disc and the shaft rotation eccentric. According to the relevant information and the usual method of adjustment, time-consuming adjustment, it is time to introduce a new method, adjusted in the test site is very convenient.
