Mill Machinist

CNC Horizontal Boring Mill Machinist

This role focuses on operating and setting up a 3-axis CNC horizontal boring mill on 2nd shift in a small, family-style job shop environment. You will perform complete machine setups, make precise offsets and adjustments, interpret G and M code and blueprints, and work with large, delicate castings and steel components. The position requires hands-on involvement from initial setup and first-piece inspection through metrology checks and final part washing in preparation for packing.

• Perform full setups on CNC horizontal boring mills, averaging approximately two setups per day.
• Make offsets and adjustments at the machine to ensure parts meet tight tolerances of +/-.005 inches.
• Read and interpret blueprints, engineering drawings, and work instructions to determine machining requirements.
• Understand and work with G and M code to run and adjust CNC programs as needed.
• Change out tooling, including tool holders and inserts, and verify correct tooling for each job.
• Work with large and delicate castings and steel parts, ensuring careful handling and accurate fixturing.
• Create and maintain a true position (zero-point) for accurate part location and repeatability.
• Perform first-piece inspections and verify dimensions using precision measuring tools such as micrometers, calipers, bore gauges, and gauge pins.
• Run metrology checks on parts throughout the machining process to confirm dimensional accuracy and quality.
• Wash and clean completed parts to prepare them for packing and shipment.
• Safely operate an overhead crane or hoist to move casings and other large work pieces.
• Follow job shop machining practices, including handling multiple setups and change-outs per day in a low-volume, high-mix environment.
• Collaborate with team members and communicate any issues with tooling, programs, or quality.
• Maintain a clean, organized, and safe work area and follow all shop safety procedures.
• Demonstrate a commitment to continuous learning and skill development in CNC machining.

• 3–5+ years of hands-on experience operating and setting up 3-axis CNC mills in a job shop environment.
• Proven ability to perform complete setups, change out tooling, and make on-the-fly adjustments at the machine, averaging two setups per day.
• Strong ability to read and interpret blueprints and engineering drawings.
• Working knowledge and understanding of G and M code for CNC machining.
• Demonstrated ability to consistently hold tolerances of +/-.005 inches.
• Experience using precision quality instruments such as micrometers, calipers, bore gauges, and gauge pins.
• Job shop machining experience with multiple setups and change-outs per day.
• Comfort working with different metal materials, primarily castings and steel.
• Ability to safely handle and machine large and delicate work pieces.
• Capability to perform first-piece inspections and in-process dimensional checks.
• Willingness and ability to work 2nd shift, Monday through Friday, from 3:00 p.m. to 12:00 a.m.

• Experience operating horizontal boring mills.
• Familiarity with Fanuc CNC controllers.
• Experience working specifically with large or delicate components that require careful handling.
• Hands-on experience with Kizer or Kuraki boring mills.
• Overhead crane or hoist operation experience for moving large parts and casings.
• Programming knowledge of G and M code to edit or create CNC programs at the machine.
• Ownership of personal precision measuring tools such as micrometers, calipers, bore gauges, and gauge pins, demonstrating personal investment in the trade.
• Strong desire to learn, grow, and continue developing skills in CNC machining and horizontal boring mill operations.
• Background in military service is welcomed as an indicator of discipline, reliability, and teamwork.
