Position Summary

To set up and operate thread grinding and/or milling machines to rough, finish and semi‑finish rotors, shafts, grooves, gears, worms, splines, and screw gears to size, index, form and finish as required.

Responsibilities

• Operate two or more machines to rough and finish grind or mill rotor threads to form, size, index, and finish as required to produce proper contact.
• Operate up to four machines (shaft lathe, thread mill, NCG and a thread grinder) in a rotor cell, while meeting daily throughput demands.
• Check rotors for form using rotor master, form gages, and other measuring devices.
• Make adjustments when necessary to produce proper form.
• Operate N.C. controlled machines.
