What are the responsibilities and job description for the High-Speed CNC Milling Technician (Siemens 840D) position at Aegis Manufacturing & Engineering?
Shape precision parts at high RPMs
Picture your day: you open a new work order, study the blueprint and work instructions, confirm dimensions and tolerances, choose fixtures and workholding, and bring a CNC mill to life. You align and secure the workpiece, dial in tool offsets, and run a first article. You verify results with precision measuring instruments, document the inspection, and fine-tune speed, feed, depth, and cutting angles to lock in repeatable accuracy—especially at 16,000–27,000 RPM. Throughout the run, you monitor the machine, utilize probing, and make proactive adjustments to keep parts within spec. When the job wraps, you leave a clean, orderly, and safe workspace.
What you'll do- Read and interpret blueprints, technical drawings, work instructions, and specifications to determine machining requirements, dimensions, tolerances, and setup procedures.
- Select, align, and secure workpieces using appropriate tooling, fixtures, and workholding methods.
- Set up and operate CNC machines to produce parts according to specifications.
- Adjust machine settings—including speed, feed, depth, and cutting angles—to maintain quality and accuracy.
- Monitor machine operations, identify potential issues, and make adjustments to prevent defects or out-of-tolerance conditions.
- Inspect finished parts using precision measuring instruments to verify compliance with specifications and quality standards.
- Complete first-piece inspections and document inspection results as required.
- Maintain a clean, organized, and safe work area while following established safety procedures.
- Trade school, vocational training, apprenticeship, or equivalent machining education and experience.
- Three to five years of CNC machining experience preferred.
- General machining knowledge, including shop math, blueprint reading, geometric dimensioning and tolerancing (GD&T), and precision measurement.
- Experience with machine and tool probing.
- Ability to interpret technical drawings and work independently to meet quality and production requirements.
- High-speed machining experience preferred, particularly with spindle speeds of 16,000–27,000 RPM.
- Experience with Siemens 840D controls is a plus.
- Specialized experience with specific machining processes or equipment may be required for certain positions.
- GD&T
- CNC Tooling
- CNC Machine Repair
- Tolerance Analysis
- CNC Machine Setup & Changeover
- Blueprint Reading
