Location: Roseville, MI

Pay Scale: $24$28/hour to start with performance-based increases available at 612 months

We are seeking a skilled and dedicated CNC Operator / Grinder (OD/ID) to join our team. The Grinder will be responsible for operating and maintaining grinding machines, focusing on external (OD) and internal (ID) grinding processes. The ideal candidate will have strong attention to detail, excellent problem-solving skills, and the ability to produce high-quality precision components.

This is a trainable, tiered position with growth opportunities across three levels from entry-level operators to experienced precision grinders. Depending on your background, you may enter at any of the three skill tiers, with clear pathways for advancement based on performance, skill development, and experience.

Essential Functions:

• Operate CNC and manual OD/ID grinding machines to produce high-precision components.
• Load and unload parts between centers or into chucks/collets.
• Monitor machine performance, grinding cycles, coolant flow, and wheel condition.
• Perform inspections using precision measuring tools (micrometers, bore gauges, indicators).
• Read and interpret blueprints, operation sheets, and GD&T symbols.
• Set up and align grinders, mount wheels, dress and balance grinding wheels, and achieve tight tolerances.
• Collaborate with quality and engineering teams to ensure accuracy and process improvements.
• Maintain a clean, organized, and safe work environment following 5S and safety standards.

Position Requirements:

• A High School Diploma or equivalent.
• Strong attention to detail and mechanical aptitude.
• Basic to advanced understanding of OD/ID grinding principles (training provided for entry-level).
• Ability to perform or learn setup, dressing, and in-process measurement procedures.
• Familiarity with blueprint reading and precision measurement tools.
• Commitment to quality, teamwork, and continuous improvement.

Preferred Qualifications:

• 310 years of OD/ID grinding experience in precision manufacturing.
• Experience with gear, aerospace, or bearing components.
• Ability to hold tolerances within 0.0001" and achieve fine surface finishes.
• Knowledge of grinding wheel selection, speeds/feeds, coolant requirements, and complex geometries.
• Experience training others or leading setup operations is a plus.

Work Environment & Physical Requirements:

• Standing for extended periods while operating grinding machines.
• Frequent lifting (up to 25 lbs.), bending, and handling of precision components.
• Exposure to coolant, grinding dust, and high-noise environments (PPE provided).
• Working with high-speed rotating equipment requires focus and adherence to safety protocols.
