CNC Milling Machine Operator

Craft precision parts as our next CNC Milling Machine Operator Picture your day in our Inland Empire (IE) facility: you review the job traveler, load tools, dial in work offsets, and send your first program to the machine. You listen for spindle chatter, watch chips break cleanly, tweak feeds and speeds, and verify dimensions with micrometers and calipers. By mid‑day, you’ve fine‑tuned an offset, documented run data, and teamed up with a fellow machinist to solve a tricky feature.

Before you clock out, you complete routine upkeep and leave the cell spotless and safe.

What you’ll take on Prepare and run CNC vertical milling equipment based on prints, models, and specifications.

Observe cycle performance, adjust tooling, offsets, and parameters to maintain capability and throughput.

Execute daily preventative maintenance to keep machines production‑ready.

Verify parts using precision metrology (micrometers, calipers, gauges) to ensure conformance.

Partner with teammates to troubleshoot machining or quality issues and implement corrective actions.

Sustain a clean, organized, and safe work cell aligned with shop safety standards.

Record setups, run notes, and inspection results with accurate, timely documentation.
