Grinding of the micrometer
I. Overview The micrometer is a relatively precise measuring tool, which is widely used in various fields of machining. The accuracy of the measuring surface of the micrometer, the geometric error and the parallelism between the measuring anvil and the measuring surface of the measuring rod directly affect the accuracy of the workpiece to be tested. In the production, the measuring surface is finally completed by the grinding process, so the mechanism of the analytical surface grinding is extremely important. The author is experimenting
