What is the Electropolishing and Polishing?
Electropolishing is an electrochemical finishing process that removes a thin layer of material from a metal part, typically stainless steel. The process leaves a shiny, smooth, ultra-clean surface finish.
Polishing is a finishing method that uses an abrasive material to smooth surfaces. When polished, the surfaces of metallic objects are freed of defects and become more reflective and shiny, enhancing their appearance. .
Difference between Electropolishing and Polishing
|Through electropolishing to have smooth and bright metal surface||Through abrasion,cutting and deformation to have smooth and bright metal surface|
|Passivation film is formed on the metal surfaceN||No passivation film is formed|
|Complicated shapes and small workpieces can be processed||Only to make the simple shape metal parts|
|Fast production speed with cheaper cost||Slow production speed with higher cost|
