CNC Mill-Turn Operator - 2nd Shift

PURPOSE:

The CNC Mill-Turn Operator safely operates and monitors multi-tasking CNC equipment that combines turning and milling operations in a single machine or cycle. Equipment may include Mazak INTEGREX e-670 and other INTEGREX-style machines, and Doosan/DN Solutions twin-spindle, twin-turret turning centers. The operator loads and verifies work pieces, runs approved programs, monitors cutting tools and coordinated machine movements, inspects precision parts, and maintains accurate production records.

The position requires close attention to complex machine motion, quality, and safe work holding; programming and major setup changes remain with authorized personnel.

• Operate assigned CNC mill-turn machines to perform turning, milling, drilling, boring, and related machining operations in accordance with approved programs, routers, and work instructions.
• Read and follow blueprints, operation drawings, setup sheets, and inspection plans; understand part orientation, critical dimensions, datum relationships, and applicable geometric tolerances before machining.
• Load and unload material and work pieces using approved chucks, jaws, fixtures, supports, and lifting devices. Confirm part seating, clamping, and safe clearance before starting a cycle.
• Monitor coordinated machine functions such as main/sub-spindle operation and part transfer, upper/lower turret activity, live tooling, and B-, C-, or Y-axis movement, as equipped. Recognize potential tool, turret, spindle, and workpiece interference.
• Verify proper workpiece location and secure gripping during automated spindle transfers or secondary operations when applicable; stop and notify supervision if alignment or clamping is in question.
• Check tool condition, insert wear, tool seating, and tooling identification. Replace approved inserts or tools and make authorized wear-offset adjustments within documented limits; refer major corrections to qualified personnel.
• Monitor cycle performance for alarms, abnormal sounds, vibration, chatter, poor surface finish, dimensional drift, coolant problems, chip buildup, and unexpected motion; stop and elevate concerns promptly.
• Complete first-piece, in-process, and final inspections as required, including inspections after tool changes or process interruptions, and document actual results on the specified forms.
• Use calibrated measuring equipment such as micrometers, calipers, bore gauges, indicators, and other approved gauges; request additional inspection support when required.
• Follow material identification, serialization, lot traceability, tagging, and nonconformance procedures. Keep accepted, held, and rejected parts properly identified and segregated.
• Record production quantities, scrap/rework, downtime, tool changes, and other required job data; follow established cycle-time expectations without sacrificing safety or quality.
• Perform routine operator-level machine checks, including coolant condition/level, lubrication indications, chip removal, and general housekeeping, according to the preventive maintenance checklist.
• Support authorized setup personnel during changeovers, tool verification, and process troubleshooting; do not independently alter programs, critical offsets, or machine settings without approval.
• Maintain a clean and orderly machine and surrounding work area. Follow safe chip-handling, guarding, lifting, and machine-access practices at all times.
• Communicate production status, quality concerns, unfinished work, and machine issues to the supervisor and incoming shift; perform other duties as assigned.

• High school diploma or equivalent, or at least six months of relevant machine shop or manufacturing experience; willingness to develop additional machining skills.
• Mechanical aptitude and ability to learn CNC multi-tasking equipment. CNC lathe, mill-turn, or multi-axis machining experience is preferred but not required for an entry-level operator.
• Ability to read shop drawings, routers, and basic machining dimensions; familiarity with geometric dimensioning and tolerancing (GD&T) is a plus.
• Ability to use precision measuring instruments and consistently follow quality, inspection, and traceability requirements.
• Familiarity with MAZATROL and/or Doosan/FANUC-style CNC controls, tool offsets, live tooling, and multi-spindle operations is preferred.
• Ability to safely handle…
