• Perform first piece inspections to verify that initial parts meet all specifications before continuing production.
• Conduct in-process inspections using gauges and other measuring instruments to ensure parts remain within specified tolerances throughout the run.
• Use measuring instruments such as calipers, outside and inside micrometers (OD/ID mics), and depth micrometers to verify dimensions.
• Read and interpret blueprints and written work instructions to determine machining operations, sequence, and dimensions.
• Follow established work instructions and quality procedures to ensure consistent and repeatable results.
• Maintain a clean and organized work area and handle equipment and tools with care.
• Collaborate with team members and communicate any issues related to quality, equipment, or process.

• Experience working with short runs and small batch production, often under 30 pieces per order.
• Comfort working with setup sheets and standardized documentation for each part.
• Familiarity with both CNC mills and CNC lathes.
• Ability to manage multiple setups in a single day while maintaining quality and efficiency.

The organization offers a stable, weekday schedule and the opportunity to work with a variety of parts and setups, which keeps the work engaging and technically challenging. You will develop and refine your machining skills in an environment that values precision, craftsmanship, and consistent quality. The focus on smaller batch sizes provides a dynamic setting where you can broaden your experience across different parts and processes.
