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...

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...

Ra simply, is the mean roughness; the average calculated from the peak heights and valley depths. A surface that is mostly spiked can have the same Ra value as one that is mostly troughed- but each could have a very different impact on seal performance. Nowadays, surface finish measuring ...
Today, surface finish is still typically described using only an Ra value, despite its incapacity to describe the subtlety of real surfaces. This ongoing attachment to Ra is largely due to two leading factors: ease of low-cost 2D measurements with a stylus profilometer, and easy access to hist...
