Job Description

The CNC Milling Operator / Machinist sets up and operates CNC vertical milling machines to produce precision features on fabricated and welded components. This role directly supports value-added manufacturing operations by ensuring all parts meet dimensional, quality, and customer specifications. You will work hands-on in a high-mix manufacturing environment, applying strong setup capability, solid machining fundamentals, and careful inspection practices to deliver high-quality parts consistently.

Responsibilities

• Set up and operate CNC vertical milling machines to produce components to specified dimensions and tolerances.
• Load, verify, and run CNC programs on the machine, including setting tool and work offsets and performing test runs to confirm accuracy.
• Read and interpret engineering drawings, blueprints, and setup sheets to determine machining requirements and sequence of operations.
• Select appropriate cutting tools and determine correct feeds and speeds based on material, tooling, and required surface finish.
• Make minor program edits and adjustments at the machine to optimize performance and correct issues as needed.
• Perform in-process inspections using standard measuring equipment such as calipers and micrometers to verify dimensions and quality.
• Maintain dimensional accuracy, surface finish, and overall part quality in line with customer and internal standards.
• Identify machining, quality, or process issues promptly and communicate them to management to support continuous improvement.
• Maintain a clean, safe, and organized work area in accordance with established safety standards and shop practices.
• Support metal fabrication machinery operations as needed when machining workload is lighter, working in that department as required.
• Follow all shop procedures, quality guidelines, and safety protocols, and complete other duties as assigned by management.

Essential Skills

• Minimum 3 years of experience operating CNC vertical milling machines.
• Proven ability to independently set up and operate CNC vertical mills from start to finish.
• Strong familiarity with Haas CNC machines and Haas controllers.
• Ability to read and interpret blueprints and basic GD&T to understand tolerances and part requirements.
• Solid understanding of machining principles, tooling selection, feeds, and speeds for various materials.
• Experience performing precision measurement and inspection using calipers, micrometers, and other standard tools.
• Ability to work with G and M code for CNC machining operations.
• Hands-on experience in CNC milling, including machine setup, tooling, and operation.
• Strong attention to detail and a consistent commitment to producing high-quality work.
• Ability to work effectively in a high-mix manufacturing environment with varied parts and setups.

Additional Skills & Qualifications

• Experience machining welded or fabricated components.
• Experience in fabrication or mixed-process manufacturing environments.
• Familiarity with fixturing for irregular or non-standard parts.
• Experience working with vertical mills beyond Haas, including other CNC platforms such as Fanuc-controlled machines.
• Understanding of machining programming concepts and basic on-machine programming or program editing.
• Exposure to metal fabrication machinery and willingness to support that department when machining workload is lighter.
• Ability to interpret detailed blueprints and setup sheets for complex parts.
• Comfort working with various tooling solutions to optimize machining performance and part quality.
