我国原来采用表面光洁度,现全部由表面粗糙度标准替代,这不单纯是名称和代号的更改,而是有许多实质性区别。粗糙度是指加工表面上具有的较小间距和峰谷所组成的微观几何形状特性,能较全面、确切的表达表面粗糙不平的程度。光洁度是指表面光滑洁净的情况,是从人的视觉观点提出来的。粗糙度与光洁度的最大区别是表达的方式(包括分级、评定参数和标注方法等)的不同。光洁度分∽、
Our original use of surface finish, are all replaced by the standard surface roughness, this is not simply the name and code changes, but there are many substantive differences. Roughness refers to the processing of the surface with a small pitch and peak valley composed of the micro-geometry characteristics, more comprehensive and accurate expression of the surface roughness level. Smoothness refers to the surface smooth and clean situation, put forward from the human visual point of view. The biggest difference between roughness and finish is the way of expression (including grading, evaluation parameters and labeling methods, etc.). Finish score,
