How to Achieve Ra 0.4m Surface Finish on Stainless Steel
Since you are working with stainless steel, surface finish is very crucial. It can be difficult to get a Ra 0.4m surface finish on stainless steel, but you can do it if you have the right tools and techniques. In this post, we’ll cover how to prep and clean stainless steel prior to finishing, what tools and techniques to use to obtain a Ra 0.4m finish, tricks on how to not get a rippled appearance when finishing, and how to maintain the finish.
Why Is Surface Finish So Important In Stainless Steel?
The surface finish of a material is the smoothness or roughness of a material's surface. It is essential for stainless steel, for it’s appearance and for how well it performs. In addition to being attractive, a smooth surface finish can assist in staving off rust and corrosion. The Ra 0.4m is a super smooth finish and defect free finish so it is easier to keep clean and maintain.
Pre-prep and Wash Stainless Steel Prior to Finishing
Stainless steel need to be well-prepped and clean before it gets at Ra 0.4m surface finish. Begin by washing away any dirt, grease or other substances on the surface with mild soap and water. You can also employ a degreaser or cleaner for heavy stains.
When the surface is clean, sand any rough spots with fine-grit sandpaper or a sanding pad. Be sure to sand in the direction of the stainless steel’s grain to prevent scratches. Once the surface has been sanded, wipe it once again, remove dust and possible residue brought by milling process.
Selecting the Best Tools and Methods for a Ra 0.4m Finish

Tips for a Smooth, Uniform Surface Texture
So a Ra 0.4m surface finish on stainless steel is something that takes time and skill to achieve. Below are some tips:
Work in cheap cnc machining an area that is clean and well-lighted so you are able to easily see any defects in the wood.
Sand or polish lightly to avoid removing too much material.
Work slowly, and be sure it is even over the whole.
Test your work by wiping it down with a clean cloth and see if there are any remaining imperfections.
If you find deeper scratches you may need a cnc machining metal coarser abrasive to remedy them.
