Metal Polishing & Buffing


The term polish has different meanings depending on who you are talking to. The Metal Finishes Guide defines metal polishing as a process that enhances the surface of a part by means of metal removal. Nearly all industries use polishing because it enhances the surface of a part, making it ready for use or to receive one of our high-performance finishes.

Metal Polishing and BuffingSurface Polishing Methods

  • Use of an abrasive belt (sandpaper)
  • Use of an abrasive wheel (a wheel manufactured with an abrasive in it)
  • In a mass finishing process with abrasive media

All of the processes mentioned above RPA uses to help reach the final finish of a customer’s product. Whether it is metal finishing, plastics finishing, or composites finishing some removal of the surface is required. RPA has developed over many years of experience a combination of processes such as vibratory polishing, polishing on a belt or wheel, mass finishing or tumbling, and even bead blasting to achieve the desired finish of the customer.


Buffing, unlike polishing, is the process that will give the part its final finish; this can be accomplished in many different ways. Depending on the desired finish of the customer, you can go from bright to dull, or mirrored to a satin or brushed look. The industries that typically utilize this finish include the medical industry, such as hospitals, or any industry where the finished part must look very clean, such as automotive.

Various Ways to Reach the Desired Finish

  • Cotton wheel with a specific compound
  • Mass finishing with various medias
  • Bead blasting

In many cases when a customer talks about a buffed finish, it will usually mean a bright, maybe a mirror finish with no scratches or noticeable marks.
