About The Position

This role involves operating CNC turning centers, vertical machining centers, and other CNC equipment. The machinist will be responsible for machine start-up, shutdown, and inspections, as well as loading and unloading materials and components. Key duties include performing setups, changeovers, installing and replacing tooling, and setting/verifying offsets. The position requires reading and interpreting engineering drawings, understanding GD&T, and verifying part dimensions using various precision instruments. The machinist will perform first-piece and in-process inspections, document results, monitor operations for quality issues, troubleshoot routine problems, and perform deburring and secondary operations. Maintaining production rates, following CNC programs, making minor program edits when authorized, and performing basic preventative maintenance are also essential. The role includes maintaining a clean work area, completing documentation, adhering to safety procedures, and assisting/training less experienced operators.
