Edge and Surface finishing with ECM

摘要

Components ranging from artificial implants to diesel injector parts have requirements for edge and surface finishing that are becoming more challenging to meet on a cost effective basis. Manufacturing engineers are more frequently drawing on the capabilities of Electrochemical Machining (ECM) to meet these requirements that are as varied as the range of applications. Deburring, edge radiusing, contouring, and surface roughness reduction are some of the material removal objectives being met with ECM. Intrinsic process benefits, such as, very fast metal removal rates, stress free results, internal surface polishing (including some complex geometry), and non-consumed tooling have added to its popularity. ECM finishing provides high quality, accurate results on medium to high quantity applications and a sampling of these will be used to describe the different ways this technology is applied to production parts. Production equipment and process factors are described.
