Q.I have just purchased a surface finishing tester and need to understand what the Ra reading is telling me in microns. For instance if I have a 0.6Ra finish that requires taking down to 0.4Ra, How many microns of metal will I be removing and what will the finish micron be ? Is ther...
surface finish的基本含义是表面精饰、表面光洁度或表面粗糙度。它指的是物体表面的微观不平整程度，这种不平整度会对表面的外观、质感、反光性、耐磨性、耐腐蚀性以及与其他材料的结合性能产生影响。surface finish通常使用各种测量工具和参数来量化，如表面粗糙度仪可以测量表面的微观高低起伏，而常用的参数...
