Why This Role Exists

This role exists to support growing demand for high-precision components at Gretna Machine Shop, particularly in aerospace and energy applications where EDM is critical.

As the shop continues to expand capabilities, this position plays a key role in producing complex parts that require tight tolerances, intricate geometries, and high surface finish standards.

This is a strong opportunity for:

• Operators looking to step into programming
• Programmers who want to work on real, high-spec EDM work

The Work You’ll Be Doing

• Program, set up, and operate ONA Wire EDM machines
• Develop and edit EDM programs (machine control and/or offline CAM)
• Read and interpret blueprints, CAD models, and GD&T
• Select proper wire, flushing strategy, and cutting parameters
• Perform setups, offsets, alignments, and first article inspections
• Monitor machining for accuracy, surface finish, and tolerance
• Inspect parts using micrometers, calipers, height gauges, and comparators
• Troubleshoot issues (wire breaks, accuracy, process deviations)
• Perform routine maintenance and keep machines running efficiently
• Support production while machines are running (deburring, marking, etc.)
• Collaborate with engineering, quality, and machining teams
