"Steel ball polishing"



 

Dear Sir,

We are manufacturing stainless steel 304 bowls for export purposes. The bowls need to polished from both inside and outside. We have tried all the options of polishing and have finally settled for STEEL BALL POLISHING (vibratory), which our buyers have agreed to.

To hide the draw marks & to achieve a better surface for steel ball polishing, we have got the bowls shot blasted with glass beads before putting it in for steel ball polishing.

Our buyers say that the polish is too matte. They want us to increase the shine and luster.

Is it because of the shot blasting that the polish is matte? How can we achieve more shine ?

Thanking You.

Do not blast your work before finishing. The surface finish of your base material from the mill is no rougher than 35 RMS. The finest finish you can obtain from most blast systems is around 35 RMS but typically is 95 or greater. That means your best option is to use abrasive belt or wheel on the rough metal seam or use medium to fine ceramic media prior to ball burnishing.
