Job Description & How to Apply Below
We're looking for a Senior 5-Axis Machinist who can own complex jobs from print to part: programming, setup, prove-out, and production, while maintaining tight tolerances and excellent finishes. You'll primarily run a Hermle C-400 (Heidenhain control) and support additional equipment including a Hyundai WIA HD 3100SY mill/turn and a Fanuc Robodrill. This is a hands-on role in a high-mix, low-volume environment where quality, process discipline, and problem-solving matter.
Key Responsibilities- Set up, operate, and maintain a Hermle C-400 5-axis machining center (Heidenhain control) to produce high-quality parts.
- Program and edit toolpaths in Fusion 360 and Esprit Edge, including 3+2 and full 5-axis strategies as needed.
- Set up and run a Hyundai WIA HD 3100SY (live tooling, 6" sub-spindle
, Fanuc i-Series) for mill/turn work, part transfers, and process optimization. - Set up and operate a Fanuc Robodrill (
Fanuc Series 31i-Model B5
) for production and support work. - Interpret engineering drawings, models, and route sheets to execute precise machining tasks.
- Select tooling and work holding; set offsets; dial in feeds/speeds to optimize cycle time, tool life, and part accuracy.
- Perform first-article, in-process, and final inspections using precision measuring instruments (micrometers, calipers, indicators, height gauges, bore gauges, etc.).
- Troubleshoot machining and process issues (chatter, tool wear, runout, alarms, dimensional drift) and implement corrective actions.
- Document setups and best practices (tool lists, work offsets, inspection notes) to support repeatability and team success.
- Collaborate with engineering and production to improve manufacturability, reduce scrap, and strengthen process capability.
- Maintain a clean, organized, and safe work area; follow all safety standards and shop protocols.
- Support and mentor other machinists as needed to hit schedule and quality targets.
- Proven CNC machining experience with strong capability in 5-axis setup and operation (Hermle experience is a big plus).
- Fusion 360 CAM proficiency (able to program, post, and adjust toolpaths; comfortable with prove-out and iteration on the floor).
- Experience with Heidenhain controls (or strong ability to ramp quickly).
- Solid mill/turn experience preferred—especially with live tooling and sub-spindle work (Hyundai WIA HD 3100SY or similar).
- Familiarity with Fanuc controls
, ideally including Fanuc i-Series and Fanuc 31i platforms (Robodrill experience is a plus). - Strong ability to read and interpret prints,
GD&T, and technical specifications. - Deep understanding of machining principles, tooling selection, work holding, and material behavior.
- Skilled in precision measurement and inspection; high attention to detail and pride in workmanship.
- Able to work independently, communicate clearly, and collaborate in a fast-moving team environment.
- Previous experience in a high-mix, low-volume manufacturing environment is a plus.
