Industry & Occupation
Classification
Summary
A metalworking technician who performs gear cutting on cylindrical workpieces such as gears using a hob machine.
Description
Hob machine operators specialize in operating hob machines (gear cutting machines) for cutting processes on gears and splines, setting cutting conditions (rotation speed, feed rate, depth of cut), and performing gear cutting on workpieces. They handle installation and positioning adjustments of cutting tools (hob cutters), manage tool sharpness, and conduct post-processing inspections of dimensions and tooth profiles (using micrometers, calipers, gear measuring instruments, etc.) to ensure standards and accuracy. They also perform daily machine inspections, tool management, maintenance of lubrication and cooling, input and adjustment of machining programs (for CNC hob machines), and collaborate with production technology and quality control departments to improve processes and yield rates.
Future Outlook
Amid advancing automation and labor reduction in manufacturing, skills in responding to CNC compatibility and smart factories utilizing IoT are required. Demand for personnel with high-precision machining technology is expected to remain stable.
