CNC Operator

Key Responsibilities

Setup, adjust, and operate 3-axis, 4-axis, or 5-axis DMG MORI CNC milling and turning machines . Load raw materials, install fixtures, dial in work offsets, and set up cutting tooling (end mills, drills, taps, inserts, etc.) Perform dry runs, single-block execution, and first-piece inspections to verify setup before full production runs.

Programming & Control: Read, interpret, and edit Siemens Sinumerik programs directly at the controller using G-code/M-code or conversational programming ( Shop. Mill / Shop. Turn ). Make parameter adjustments, tool length offsets, cutter compensation, and feed/speed tweaks as needed. Quality Control & Inspection: Read and interpret complex engineering blueprints, drawings, and GD&T (Geometric Dimensioning and Tolerancing) callouts.

Inspect finished parts using precision measuring instruments including micrometers, calipers, height gauges, bore gauges, and CMM outputs. Ensure components consistently meet tight tolerances (e.g., $\pm 0.0005''$ / $\pm 0.01 \text{ mm}$). Maintenance & Troubleshooting: Conduct daily and weekly preventive maintenance on DMG MORI machines (coolant levels, lubrication system, chip conveyor, spindle check).

Diagnose operational issues, tool wear, and chatter; make real-time adjustments to cutting parameters. Required Qualifications & Experience Experience: Minimum 3–5 years of hands-on experience operating CNC machines in a precision manufacturing environment. Machine Expertise: Demonstrated, recent experience running DMG MORI CNC machines (DMU, CMX, NLX, NTX, or similar series).

Control Language: Proficiency in Siemens Sinumerik controllers (840D / ONE / Shop. Mill / Shop. Turn / Operate).

Education

High School Diploma, GED, or Trade School Certificate / Vocational Diploma in Machine Tool Technology or Precision Machining. Blueprint Reading: Advanced ability to read technical drawings, CAD prints, and GD&T symbols. Measuring Tools: Mastery in using hand measurement tools (micrometers, gauge blocks, dial indicators).

Preferred / Desirable Skills Experience with CELOS user interface on DMG MORI machines. Knowledge of Fanuc or Heidenhain controls is a plus. basic CAM software knowledge (e.g., Mastercam, NX, or Esprit). Experience machining tough materials (Inconel, Titanium, Stainless Steel, Tool Steels).
