So if I understand this right, you are requesting info on the difference between the RA's in which case, the lower the number the smoother the surface finish. I don't think you are talking about different measurement scales, are you? AF Kenton retired business owner - Hatboro, ...
解析 1、50MICRO-inch是指50微英寸.1英寸=10的6次方微寸=25.4mm.50微寸=0.00005英寸=0.00127mm. 2、Ra是化学元素镭,常用于电镀(plating). 3、surface finish是指表面完成电镀. 总上所述:表面电镀0.00127mm的镭. 分析总结。 1英寸10的6次方微寸254mm50微寸000005英寸000127mm...

Q.We are regularly machining Cylinder Heads & Blocks. For Head contact face in case of Block and block contact face in case of head specifies surface finish of 15 Rz. After finish milling when we check for Rz it is between 15 to 20 Rz. But if we check Ra it is within 1 µRa. ...
The electropolishing process may improve a surface finish by up to 50%. The electropolishing reaction removes material while it improves surface roughness. Because of the material removal, process runtimes are often limited to maintain dimensional tolerances. Limited runtimes result in real world surface...

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...
