Industry & Occupation
Classification
Summary
Manufacturing technician who finishes the inner surfaces of metal cylindrical parts using polishing tools and abrasives to ensure dimensional accuracy and surface quality.
Description
Cylinder inner surface polishers polish the inner surfaces of cylindrical parts such as engine components, cylinders, and pipes using specialized polishing machines, buffs, diamond bars, and other hand tools to achieve specified dimensional tolerances and surface roughness. They read drawings and set polishing conditions (rotation speed, abrasive type, pressure). After processing, they inspect using micrometers and surface roughness testers, re-polishing any defective areas. They select polishing methods based on differences in materials and heat treatments, managing finishing accuracy.
Future Outlook
Due to advances in automation and CNC, there is a decreasing trend in mass production fields, but hand-finishing techniques for high-precision parts and small-lot production continue to be in demand.
