Position Summary
We are seeking a skilled CNC Lathe Operator with 2–5 years of hands-on machining experience to join our aerospace manufacturing team. In this role, you will be responsible for setting up, operating, and maintaining CNC turning centers to produce precision components that meet strict aerospace tolerances and quality standards. You will work from engineering drawings and specifications to machine complex parts used in critical aerospace applications.
Key Responsibilities
- Set up and operate CNC lathes and turning centers (2- and 3-axis) to machine aerospace-grade materials including aluminum, titanium, Inconel, and stainless steel.
- Interpret and work directly from engineering drawings, blueprints, GD&T callouts, and manufacturing specifications.
- Load and verify CNC programs; perform offsets and tool path adjustments to maintain dimensional accuracy.
- Select and install appropriate tooling, fixtures, and work holding devices for each job setup.
- Perform in-process inspection using precision measurement instruments (micrometers, calipers, hard gauges, etc).
- Maintain in-process and final inspection documentation.
- Identify and troubleshoot machining issues related to surface finish, tool wear, chatter, and dimensional non-conformances.
- Perform routine machine maintenance including lubrication, coolant management, and cleanliness; report mechanical issues to maintenance staff.
- Adhere to all safety protocols and personal protective equipment requirements.
- Collaborate with process engineers, quality inspectors, and programmers to resolve production challenges.
- Complete work orders, traveler documentation, and production reporting accurately and on time.
Required Qualifications
- 2–5 years of CNC lathe/turning center operation experience in an aerospace, defense, or precision manufacturing environment.
- Proficiency in reading and interpreting engineering drawings, GD&T symbols, and manufacturing work orders.
- Experience with CNC controls such as Fanuc, Mazak, or similar industry-standard systems.
- Skill with precision measurement tools including micrometers, calipers, and scales.
- Familiarity with aerospace materials and their machinability characteristics (aluminum alloys, titanium, superalloys).
- Strong attention to detail and commitment to quality with a zero-defect mindset.
- Ability to lift up to 50 lbs and stand for extended periods in a manufacturing environment.
Preferred Qualifications
- Knowledge of cutting tool selection, speeds/feeds optimization, and coolant application.
- Experience in an ISO9001 or AS9100 manufacturing facility.
- Familiarity with 4- or 5-axis CNC turning/milling centers and live tooling.
- Vocational training, apprenticeship, or associate degree in machining technology, manufacturing, or a related field.
- NIMS (National Institute for Metalworking Skills) certification is a plus.
Work Environment & Physical Requirements
- Manufacturing floor environment; exposure to machine noise, coolant fluids, metal chips, and varying temperatures.
- Regular use of PPE including safety glasses, steel-toed boots, hearing protection, and cut-resistant gloves.
- Must be able to stand, walk, bend, and lift throughout the shift; occasional lifting of tooling and fixtures up to 50 lbs.
- All positions follow a 3.5 days on / 3.5 days off rotating schedule with 12-hour shifts, averaging approximately 42 hours per week.
What We Offer
- Competitive hourly wage of $22.00–$34.00/hr (Day Shift), with shift differential pay for Night Shift ($25.00–$38.00/hr), commensurate with experience.
