EDM Machinist

Duties and Responsibilities

• Set up and operate Wire EDM machines (such as Mitsubishi and Current) for production and prototype runs

• Set up and operate HP EDM machines, including electrode selection, dielectric fluid management, and gap control

• Read, interpret, and program using NC/CNC EDM code specific to EDM control systems — not general G-code programming

• Select appropriate wire types, diameters, and tension settings based on material and tolerance requirements

• Interpret engineering drawings, GD&T callouts, and 3D models to verify part conformance

• Perform in-process inspection using precision metrology instruments including micrometers, CMM, optical comparators, and surface finish gauges

• Perform secondary operations including deburring, cleaning, and surface preparation specific to EDM-produced parts

• Maintain machine electrode wear logs, dielectric fluid levels, and filter change schedules

• Troubleshoot EDM-specific issues including wire breakage, surface finish defects, and electrode wear deviation

• Ensure all finished parts meet customer specifications and internal quality standards

Minimum Requirements

• Completion of a formal EDM operator/machinist training program or apprenticeship — general CNC machinist training without EDM-specific curriculum does not satisfy this requirement

• Minimum 3 years of hands-on experience operating both Wire EDM and HP EDM machines in a production or precision manufacturing environment

• Demonstrated ability to write and edit NC programs on EDM control systems (Wire and HP)

• Proficiency reading engineering drawings with GD&T per ASME Y14.5 standards

• Experience holding tolerances of ±0.0002" or tighter on EDM-machined parts

• Experience with precision inspection equipment: micrometers, height gauges, CMM, and optical comparators

• Ability to perform all secondary operations associated with EDM-produced parts (deburring, cleaning, rust prevention)

• Physical ability to stand for extended periods, lift up to 50 lbs, and work in a manufacturing environment
