NC Machinist (Metal Processing)
えぬしーきかいこう
Industry & Occupation
Classification
Summary
Technical occupation that operates numerically controlled machine tools to machine metal parts with high precision.
Description
NC Machinists (metal processing) operate numerically controlled machine tools such as lathes and milling machines based on NC programs created using CAM software or direct input to process metal parts. Before starting work, they read machining drawings, attach materials, set cutting conditions, and select and replace tools. After machining, they measure dimensions with calipers or micrometers to confirm quality. They handle a wide range of products from mass-produced parts to prototypes, and are also required to analyze causes of machining defects and propose improvements.
Future Outlook
With advances in automation and labor reduction, demand remains stable for skilled workers proficient in advanced NC programming and 5-axis machining technology, while adaptation to new technologies such as AI control and robot collaboration is also required.
Personality Traits
Dexterous hands and good at fine work / High concentration / Meticulous
Work Style
Contract employee / Day shift / Factory employment / Full-time employee / Shift work
