一、前言随着我国精密仪器仪表工业的发展,对精密宝石轴承的测试问题应该提到议事日程上,但是由于有关这方面的高精度测试仪,目前我国很缺,对于测量半径只有1mm以下,公差在±0.02mm以内,光洁度在(?)12以上的宝石轴承凹球面弧的高精度测试仪更是看不到。为了解决急需解决的测试问题,我们对日本奥林普斯(Olympus)双光束表面光洁度干涉显微镜进行改装,将其目镜取下改装上测微读数目镜,然后用牛顿环原理进行测量,实践证明,用这 I. Introduction As China’s precision instrumentation industry, the development of precision gem bearing test should be referred to the agenda, but due to the high-precision tester in this regard, at present our country is short, the measurement radius of only 1mm below, To ± 0.02mm tolerance within the finish (?) 12 above the gem bearing concave spherical arc high precision tester is even less visible. In order to solve the test problem that needs to be solved urgently, we modified the Olympus dual-beam surface finish interference microscope, removed its eyepiece and fitted it with a micrometer reading eyepiece, and then measured it with the Newton’s ring principle.
