Location: Gilbert, AZ

On-site: Full-time

Job Summary

We are seeking a skilled CNC Mill Machinist with mid-level experience to set up, operate, and maintain CNC vertical and horizontal milling machines (including Makino and Nakamura models) in a high-precision manufacturing environment. This role emphasizes accurate setups, tool changes, real-time adjustments, and quality inspections to produce tight-tolerance metal components. The position requires strong mechanical aptitude and the ability to work independently while maintaining safety and quality standards. No advanced programming is required — focus is on proven programs with basic offset adjustments and minor G-code edits at the control (Fanuc or similar) as needed.

Key Responsibilities

• Set up and operate CNC vertical/horizontal mills (e.g., Makino high-speed/precision models, Nakamura multi-tasking milling centers) to machine parts to blueprint specifications
• Select, align, and secure workholding fixtures, cutting tools, and materials (precision vises, soft jaws, 4th-axis rotaries, collets, modular fixtures)
• Calculate and set speeds, feeds, depth of cut, and coolant flow; make real-time adjustments for tool wear, material variations, or minor process issues
• Perform tool changes and set tool length/work offsets using manual touch-off, touch probes, or presetters
• Read and interpret complex blueprints, including GD&T callouts, and follow detailed work instructions
• Conduct first-piece, in-process, and final inspections using precision tools (micrometers, calipers, bore gauges, indicators, height gauges)
• Troubleshoot common machining issues (e.g., chatter, tolerance drift, tool deflection) and implement corrective actions
• Perform daily preventive maintenance: clean machines, check coolant/lubrication levels, replace worn tools/inserts
• Document inspection results, adjustments, and nonconformances per quality procedures
• Maintain a safe, clean, and organized work area (5S standards)

Qualifications

• 1–5+ years of hands-on CNC mill machining experience (vertical and/or horizontal machines)
• Proven ability to perform independent setups and changeovers on 3-axis (or higher) CNC mills
• Strong proficiency with precision measuring instruments (micrometers, calipers, bore gauges, indicators)
• Solid blueprint reading skills, including GD&T interpretation
• Comfortable making offset adjustments and basic G-code edits at the control (Fanuc, Haas, or similar)
• Mechanical aptitude and problem-solving skills for troubleshooting machining issues
• Experience holding tight tolerances (±0.001 " or better) in production environments
• Familiarity with safety practices (LOTO, PPE, machine guarding)
• Reliable attendance and commitment to quality and continuous improvement
• High school diploma or equivalent required

Preferred

• Experience with Makino high-speed/precision mills or Nakamura multi-tasking CNC mills/lathes
• Familiarity with Fanuc controls
• Basic understanding of speeds/feeds calculations
• Forklift certification
• Exposure to ISO 9001, AS9100, or similar quality systems
• Previous work in aerospace, defense, medical, or precision manufacturing
