The OTEC Electrofinishing Process

Unlike conventional electrochemical polishing, this technology involves the workpieces moving (rotating) through the abrasive, thereby ensuring that the abrasive is circulated uniformly around them. The OTEC Electrofinishing Process uses special polymer particles suspended in an ionically conductive liquid.

OTEC’s latest-generation machines take surface processing to a whole new level. For complex geometries and additively manufactured parts, the OTEC Electrofinishing Technology is the perfect symbiosis of two established processes, delivering high-gloss results even in hard-to-reach areas. With over 25 years of experience for perfect surfaces, stainless steel, steel, brass, silver, cobalt chrome and titanium are efficiently perfected.
