Conventional / Sinker EDM Operator

Role Overview

An experienced Conventional (Sinker) EDM Operator with a minimum of 5 years of hands-on expertise is sought to join a precision-focused team. The role involves setting up, programming, operating, and maintaining RAM/Sinker EDM machinery to produce complex, high-accuracy components and tooling for demanding applications.

Key Responsibilities

• Machine operation & setup: Perform advanced setups, select tooling, align workpieces, and configure electrode systems.
• Blueprints & specifications: Interpret complex engineering drawings, 3D models, and GD&T specifications to maintain tolerances down to .0002".
• Electrode preparation: Fabricate, dress, inspect, and qualify graphite and copper tungsten electrodes.
• Process optimization: Define burn parameters, spark gaps, machine speeds, dielectric flushing, and duty cycles for alloys and tool steels.
• Quality control: Conduct in-process inspections using comparators, micrometers, height gauges, and CMM equipment to ensure zero-defect output.
• Maintenance & safety: Perform routine maintenance on EDM machines and filtration systems while maintaining a clean, safe work environment.

Required Qualifications

• Experience: Minimum 5 years operating Conventional/Sinker EDM machines in precision job shop, aerospace, or mold/die environments.
• Technical skills: Strong background in blueprint reading, GD&T, bench inspection, and electrode preparation.
• Machining math: Solid understanding of shop math, geometry, and trigonometry.
• Precision focus: Ability to work with tight-tolerance prototype and production components.
• Troubleshooting: Skilled in diagnosing cut issues, flushing problems, or surface finish defects and adjusting parameters independently.

Preferred Qualifications

• Experience with Mitsubishi & Sodick EDM controls or similar.
• Dual experience with Wire EDM or CNC Milling/Jig Grinding.
• Background in ISO 9001 or AS9100 quality environments.

Benefits

• Comprehensive health, dental, and vision insurance
• 401(k) retirement plan with company match
• Paid time off (PTO) and holidays
• Clean, climate-controlled work environment
