CNC Machine Operator

POSITION SUMMARY

The CNC Machine Operator runs milling, turning, and multi-axis machines to produce precision components for aerospace, defense, and industrial customers. This role focuses on executing established programs, loading/unloading parts, performing in-process inspections, and maintaining machine readiness in a production environment. High performers have a clear path to advance into Machinist roles as they develop setup and programming skills.

KEY RESPONSIBILITIES

• Operate CNC milling centers, lathes, and multi-axis machines following established programs and setup sheets
• Load and unload workpieces using fixtures, chucks, and workholding devices; verify proper seating and alignment
• Perform in-process inspection using precision hand tools (calipers, micrometers, bore gauges) to verify part dimensions against print specifications
• Monitor tool wear and machine performance; alert machinist or lead when offsets, tool changes, or adjustments are needed
• Maintain machine cleanliness, coolant levels, and general machine readiness
• Document production quantities, cycle times, and any anomalies on production travelers
• Work within automated and lights-out machining cells as required, including robot-assisted part loading
• Follow all safety protocols, shop procedures, and ISO 9001 quality requirements
• Communicate proactively with machinists, leads, and quality staff regarding part quality or machine issues

REQUIRED QUALIFICATIONS

• 1+ years of CNC machine operation experience in a precision machining environment
• Ability to read and interpret basic engineering drawings and understand dimensional tolerances
• Comfortable with precision measurement tools (calipers, micrometers, gauges)
• Understanding of speeds, feeds, and tooling fundamentals
• Dependable, safety-conscious, and able to maintain attention to detail through production runs
• Ability to work in a team environment and communicate effectively with machinists and leads

PREFERRED QUALIFICATIONS

• Experience on multi-axis or 5-axis CNC platforms
• Exposure to mill-turn or combined-operation machining
• Experience working with automation or robotic part-loading cells
• Familiarity with Fanuc, Mazak, Siemens, or similar CNC controls
• Experience machining aluminum, stainless, titanium, or Inconel
• Background in aerospace or defense manufacturing
