Summary
Occupation that finishes the surfaces of metal products smoothly and with high precision using lapping equipment and abrasives.
Description
Lapping finishers are specialists who polish and finish the surfaces of metal products to high precision using lapping equipment and compounds (abrasives). Based on drawings, they select appropriate abrasives and adjust machine rotation speeds and pressure while performing the work. During the process, they use measuring instruments such as micrometers and surface roughness gauges to measure flatness and roughness, refining until quality standards are met. They play an indispensable role in precision parts manufacturing lines and final machining of machine parts.
Future Outlook
While automation and advances in polishing technology will improve efficiency, demand for precision parts manufacturing remains stable, so a certain level of demand is expected to continue. Market value can be maintained by acquiring maintenance skills for machinery and equipment and quality control abilities.
