SUMMARY
We are seeking an experienced Turbomachinery CNC Lathe Operator to machine large turbomachinery bolting, including center studs and tie rods up to 2.5" diameter and 10 feet in length. This role focuses on holding tight tolerances, straightness, and runout on long, critical rotating components.
ESSENTIAL DUTIES AND RESPONSIBILITIES include the following. Other duties may be assigned.
Set up and operate CNC lathes to turn center studs, tie rods, and related hardware to blueprint specifications.
Interpret engineering drawings, work orders, and process sheets, including diameters, tolerances, GD&T callouts, and thread/fillet requirements.
Program at the control (or edit existing programs) for roughing, finishing, grooving, and chamfering on long shafts.
Set up work holding for long parts, including chucks, collets, steady rests, tailstocks, and follow rests to control deflection on up to 10' lengths.
Select and install appropriate tools, inserts, and holders for alloy steels and superalloys used in turbomachinery bolting.
Optimize feeds, speeds, and depth of cut to achieve required cycle times, surface finishes, and tool life while avoiding chatter and distortion.
Perform first article and in process inspections using micrometers, calipers, dial indicators, and surface finish gages.
Control OD size, taper, concentricity, and runout to tight turbomachinery requirements.
Diagnose and correct common machining issues such as chatter, poor surface finish, tool wear/breakage, and dimensional drift.
Complete production and quality documentation accurately on routers, travelers, and inspection records.
Maintain a clean, safe work area and follow all safety and PPE requirements.
