FABRICATED VESSEL POLISHING In most cases, extent or technique will have nothing to do with how an electropolishing job is viewed after completion. The accepted tool of inspection for industry is the profilometer. The final surface finish will either meet or not meet the surface finish criteria.The electropolishing process itself is a fairly forgiving method of achieving micro-smooth surfaces for non-stick applications. If performed correctly by an experienced vendor, surface finish compliance after completion should be a forgone conclusion. If performed incorrectly, its not unusual that you would have to re-mechanically polish prior to re-electropolishing. By the same token, if the mechanical polishing is not performed correctly prior to electropolishing, the same thing could happen. Fin-Tech has a policy of not guaranteeing final surface finish on electropolished material that we did not mechanically polish. An improperly mechanically polished surface will render poor profilometer readings after electropolishing. Its easy to see why we have adopted this policy. There is, however, a middle ground that can insure a happy medium between user, engineering firm, fabricator and electropolisher. The ultimate goal is to provide a quality product with the most cost effective means.
