磨削是精密加工的主要方法。目前,用磨削加工的方法,可以获得(?)_7～(?)_(14)的光洁表面。研究磨削表面微观不平度的形成机理从而揭示磨削表面光洁度诸量的相互关系,有助于全面掌握磨削表面光洁度的变化规律,对于合理选择和制定表面光洁度的评定标准、简化测量方法和仪器结构,具有很大的实际意义。然而,迄今为止,各国对各种不同条件下磨削表面光洁度诸标准量的相互关系,研究甚少,在技术文献中公开发表的一些理论分析结论,与磨削实际相矛盾。因此,有必要予以澄
Grinding is the main method of precision machining. At present, with the grinding method, you can get (?) _7 ~ (?) _ (14) smooth surface. Studying the formation mechanism of the microscopic roughness of the grinding surface reveals the relationship between the quantities of the grinding surface finish, which helps to fully understand the variation rule of the grinding surface finish. It is of great importance to the reasonable selection and formulation of the assessment standard of the surface finish, to simplify the measurement method and Instrument structure, with great practical significance. However, to date, there has been little research on the correlation between the standard amounts of grinding surface finishes in various countries. Some theoretical analyzes published in the technical literature have contradicted the practice of grinding. Therefore, it is necessary to clarify
