Divergent The CNC Mill-Turn Machinist is responsible for developing and executing precision machining strategies with emphasis on CNC turning and milling operations. This role partners with engineering to translate complex hardware requirements into scalable machining processes and drives continuous improvement on the shop floor.

Responsibilities

Turning & Machining Execution
Lead setup, operation, and optimization of CNC turning centers (mill-turn and multi-axis lathes) for precision components.
Execute machining & grinding across a range of equipment as needed, including 3-axis, 3+2, and 5-axis mills to support production demands.
Own first article through production runs, ensuring parts meet dimensional, surface finish, and performance requirements.
Apply advanced understanding of GD&T to validate setups and machining strategies directly on the floor.
Process Development & Optimization
Define machining strategies across turning and milling operations, including:
Tooling selection
Workholding/fixturing concepts
Program approach and sequencing
Identify and eliminate inefficiencies in cycle time, tool life, and setup methodology.
Troubleshoot and resolve machining challenges (chatter, tool wear, thermal distortion, tolerance stack-up, machine limitations).

Qualification

Proficiency with SiemensStrong understanding of G-codeWork Environment

Required

Extensive experience operating CNC turning centers (2-axis, live tooling, mill-turn, or multi-axis lathes).
Strong cross-functional machining experience including milling (3-axis, 3+2, 5-axis) & grinding.
Proficiency with Siemens, Fanuc, & Heidenhain controllers.
Advanced understanding of GD&T and its application in precision machining.
Proven ability to troubleshoot and optimize machining processes across tooling, fixturing, and programming.
Experience machining complex components in aluminum, steels, titanium, and nickel-based alloys (Inconel).
Demonstrated experience with advanced setup techniques, including dynamic work offsets and multi-operation setups.
Hands-on experience taking parts from first article through production.
Ability to create clear setup documentation and standardized machining processes.
Experience mentoring or leading other machinists on the shop floor.
Ability to lawfully access information and technology that is subject to US export controls

Preferred

Familiarity with large-format or gantry-style machining systems.
Experience Machining additively manufactured components or hybrid workflows.
Strong manual machining skills to support tooling, fixtures, and rework operations.
Experience in high-rate production or rapid development environments with aggressive timelines.
Experience in CAD/CAM software/environments (NX CAM preferred).
Strong understanding of G-code.
Experience with writing probing routines for on machine part inspections.
