Industry & Occupation
Classification
Summary
Specialized machine tool operator who uses thread-cutting lathes to perform external and internal thread processing on metal parts.
Description
Thread-cutting lathe operators handle thread-cutting lathes, a type of general-purpose lathe, to perform thread processing on metal parts including external and internal threads. They mount the workpiece, select and adjust tools, set cutting conditions (spindle speed, feed rate, depth of cut), and machine while verifying dimensions using measuring instruments (vernier calipers, micrometers, thread gauges, etc.). Depending on proficiency, they also manage setup changes, process improvements, and safety and health. Even amid advancing automation, high-precision manual machining technology is required.
Future Outlook
Demand for manual thread-cutting lathe operators is declining due to advances in automation and CNC, but skilled workers with high-precision manual processing skills remain essential for small-lot production and custom part machining.
