Mill Turn Machinist

We are seeking a highly skilled and detail-oriented Mill Turn Machinist to join our advanced manufacturing team. The ideal candidate will have extensive experience operating and programming multi-axis mill-turn CNC machines to produce precision components used in RF connectors and other high-performance applications for defense and aerospace. This position requires expertise in simultaneous milling and turning operations, tool path optimization, and working with tight tolerances on complex geometries.

• • Set up, operate, and program mill-turn CNC machines (e.g., Nakamura, Doosan, Mazak Integrex, DMG MORI NT/NX series, Okuma Multus) to produce high-precision parts.
  • Interpret complex engineering drawings, 3D models, and GD&T specifications to ensure compliance with dimensional requirements.
  • Program using CAM software (e.g., Mastercam, GibbsCAM, Fusion 360) or directly at the machine control (Fanuc conversational/G-code).
  • Perform in-process and final inspections using precision measurement tools such as micrometers, calipers, height gages, and CMMs to ensure quality.
  • Select appropriate tooling and fixturing to support multi-operation machining in a single setup.
  • Work with a variety of metals and exotic materials, including high-strength alloys, stainless steel, and other aerospace-grade materials.
  • Collaborate with engineers and manufacturing staff to refine machining strategies and improve part flow.
  • Maintain tight tolerances and surface finishes, especially on concentric and symmetric features requiring both milling and turning.
  • Ensure equipment is maintained and calibrated for optimal performance; troubleshoot machine or program-related issues.
  • Ensure adherence to quality control standards, including conducting in-process inspections and maintaining detailed production records.
  • Follow all safety procedures and maintain a clean, organized, and 6S-compliant work area.
  • Document setup sheets and tooling lists for repeatability and knowledge sharing.
  • Participate in continuous improvement efforts, lean initiatives, and training as needed.
  • Perform other duties as directed by management.

• • High school diploma or equivalent required; technical certification in CNC machining or programming preferred.
  • Minimum 6+ years of experience in precision machining, with at least 3 years operating and programming mill-turn equipment.
  • Strong proficiency in CNC programming (G-code and conversational) and use of CAD/CAM software for multi-axis operations.
  • Deep understanding of multi-axis tool paths, work offsets, sub-spindles, and live tooling integration.
  • Solid knowledge of geometric dimensioning and tolerancing (GD&T) and the ability to work from complex part prints and solid models.
  • Familiarity with high-performance materials including stainless steel, titanium, Inconel, and other aerospace-grade alloys.
  • Skilled in using a variety of precision inspection tools, including CMMs.
  • Excellent troubleshooting skills and ability to optimize cycle times and minimize tool wear.
  • Strong work ethic, attention to detail, and commitment to delivering defect-free components.
  • Excellent problem-solving skills and the ability to work independently and as part of a team.
  • Ability to work under pressure and meet tight production deadlines.
  • Physical ability to lift/move up to 40 lbs, perform repetitive tasks, and stand for extended periods.
  • Prior experience in defense, aerospace, or RF component manufacturing is a strong plus.
  • Ability to work both independently and as part of a self-managed team.
