Job Title: CNC Machinist
Job Description

The CNC Machinist operates and sets up 3- and 4-axis vertical and horizontal CNC mills in a predominantly sheet metal machining environment. Machines run off MasterCam software and utilize controls such as Haas and Fanuc. This role supports both commercial and defense contracts, contributing to a fast-growing, cash-positive operation. The position is on a swing shift with a 4/10 schedule, focusing on precision machining, inspection, and adherence to quality and safety standards.

Responsibilities

• Operate 3- and 4-axis vertical and horizontal CNC mills to machine sheet metal components according to engineering drawings and specifications.
• Follow verbal machine operation instructions from department leads and review drawings and manufacturing planning to understand machining requirements.
• Set up machines by installing pallets, vises, tombstones, and fixtures, and carefully load parts into machines for production runs.
• Operate machine control panels to run programs, monitor operations, unload parts, deburr components, and arrange finished parts in boxes or on pallets, including occasionally running two machines at once.
• Read and interpret blueprints, engineering drawings, specifications, manuals, tool setups, and sample parts to determine dimensions, tolerances, sequence of operations, and setup requirements.
• Measure and mark dimensions and reference points on material or workpieces as guides for subsequent machining operations.
• Use precision measuring instruments such as micrometers, calipers, bore gauges, and height gauges to monitor features and dimensions on each component run and verify conformance to requirements.
• Monitor machining processes to detect equipment malfunctions or out-of-tolerance conditions and adjust machine controls, offsets, or control media within capabilities to maintain quality.
• Report all machine malfunctions and significant process issues to the department lead in a timely manner.
• Support supervisors in running production parts, proving programs, operating controls, setting offsets, deburring, and inspecting quality parts to meet production and quality targets.
• Perform deburring of finished parts to meet surface finish and safety requirements before packaging or further processing.
• Keep equipment and work areas clean and orderly, consistently leaving the workstation in better condition than found and performing basic preventive maintenance on equipment.
• Apply basic math, geometry, and trigonometry to calculate dimensions, offsets, and machining parameters as needed for accurate part production.
• Adhere to and comply with all applicable state and federal laws, company quality programs and procedures, company policies, and safety and environmental regulations.
• Perform other related duties as assigned by management to support production, quality, and continuous improvement initiatives.

Essential Skills

• Hands-on experience operating 3- and 4-axis vertical and horizontal CNC mills.
• Proficiency with CNC machining in a sheet metal environment, with the ability to work in a shop where the majority of work is sheet metal machining.
• Ability to read and interpret blueprints, engineering drawings, specifications, and GD&T.
• Skilled in using precision measuring tools including micrometers, calipers, bore gauges, and height gauges.
• Capability to set up CNC machines, including installing pallets, vises, tombstones, and fixtures.
• Competence in following verbal instructions from leads and translating manufacturing planning and drawings into machining actions.
• Strong attention to detail in monitoring features and dimensions on each component and ensuring parts meet tolerance requirements.
• Ability to detect equipment malfunctions and out-of-tolerance machining and make appropriate adjustments within machine capabilities.
• Basic math, geometry, and trigonometry skills to support accurate machining and setup.
• Ability to deburr parts effectively and handle finished components safely and efficiently.
• Commitment to maintaining a clean, organized work area and performing basic preventive maintenance on equipment.
• Willingness and ability to comply with company quality programs, policies, and safety and environmental regulations.
• Capability to work swing shift hours (1:30 p.m. – 11:30 p.m., Monday – Thursday) on a 4/10 schedule.

Additional Skills & Qualifications

• Experience with MasterCam software for CNC programming and machine operation.
• Familiarity with Haas and Fanuc controls for CNC machines.
• Comfort working in a shop that is predominantly sheet metal machining (approximately 95% sheet metal work).
• Ability to run two machines simultaneously while maintaining quality and safety standards.
• Experience supporting supervisors and leads with proving programs, setting offsets, and inspecting production parts.
• Skill in identifying the likely results of machining actions before taking them, demonstrating good judgment and foresight.
• Flexibility to perform other duties as assigned to support production needs and continuous improvement.
• Openness to additional responsibilities or internal development opportunities (including potential DP-related responsibilities as referenced).
