Mill Machinist

Job Title: CNC Mill Machinist - Mastercam Programmer Job Description
This role focuses on setting up, operating, and programming CNC Haas mills to produce small aluminum parts in a high-quality, production-focused environment. You will handle frequent short-run batches, perform efficient setups, and program new parts from scratch in Mastercam on a regular basis. The position is ideal for a machinist who is confident in both hands-on mill setup and Mastercam programming and enjoys working in a clean, small-shop setting with strong benefits and a supportive culture.
Responsibilities

• Set up and operate a CNC Haas mill to produce parts that are typically smaller than 2 inches, with approximately 95% of work involving aluminum components.
• Perform 1-3 setups per day, with the typical trend being one setup per day, ensuring accurate and efficient changeovers between jobs.
• Run production parts with cycle times of approximately 3-10 minutes per part for the majority of operations.
• Manage batch sizes typically ranging from 5 to 20 parts, maintaining consistency and quality across all pieces.
• Program a brand-new part from scratch in Mastercam approximately once per week, handling parts of mid-level complexity.
• Focus exclusively on production machining, ensuring repeatable, reliable output rather than prototype work.
• Read and interpret blueprints to understand part geometry, features, tolerances, and required operations.
• Use precision measuring tools such as micrometers and calipers to inspect parts and verify dimensions against specifications.
• Adjust tools, offsets, and machining parameters as needed to maintain part quality and machine performance.
• Follow shop procedures and best practices to maintain a safe, efficient, and organized work area.
• Collaborate with team members to troubleshoot issues, improve setups, and optimize cycle times where possible.
• Document setups and programs as needed to support repeat jobs and consistent production results.

Essential Skills

• Proven ability to set up and operate a CNC mill in a production environment.
• Hands-on experience operating CNC mills, with familiarity with Haas mills preferred but not strictly required.
• Strong proficiency in programming parts from scratch in Mastercam; this is a critical, non-negotiable requirement.
• Ability to read and interpret blueprints and technical drawings.
• Proficiency in using precision measuring tools such as micrometers and calipers to inspect and verify parts.
• Experience working with milling operations and machining processes for metal components.
• Confidence working independently on mill setup and Mastercam programming without extensive supervision.
• Comfort working with small parts and short-run production batches, even if prior experience is with different part sizes.

Additional Skills & Qualifications

• Experience specifically with Haas CNC mills is beneficial and will help shorten the learning curve.
• Background in production machining environments where repeatability and efficiency are key.
• Familiarity with aluminum machining, including feeds, speeds, and tooling considerations.
• Strong attention to detail and quality-focused mindset when inspecting and adjusting parts.
• Ability to manage multiple jobs and setups in a day while maintaining accuracy and consistency.
• Willingness to take on overtime when available to support production demands.
