Classification
Summary
Manufacturing job that processes and finishes needle rollers (needles) used in bearings, up to quality inspection.
Description
A needle worker is a job that manufactures needle rollers used in needle bearings. After forming metal bar stock as raw material and performing heat treatments such as quenching and tempering, high-precision dimensions and surface quality are achieved using grinding machines, polishing machines, and CNC lathes. Blade changes, machine setups, and adjustments to processing conditions are performed for each process, and finally, dimensional inspections with micrometers and calipers, and appearance inspections confirm compliance with JIS standards or company criteria. They also contribute to stable production line operation and quality improvement proposals, and handle the use and maintenance of automation equipment toward smart factory implementation.
Future Outlook
While automation of manufacturing processes advances, demand continues for skilled operators in high-precision machining. Skills compatible with IoT technology and smart factories are required.
