CNC Mill and Lathe Machinist

Job Description

The Lathe and Mill Machinist is responsible for setting up and operating manual and CNC lathes and mills to produce precision machined components to blueprint and tolerance specifications. This role requires close coordination with Production, Quality, and Engineering to plan and execute job runs efficiently while supporting the company's commitment to Continuous Improvement.

About the Role

Working as part of the machine shop team, the technician is responsible for reading and interpreting blueprints, selecting appropriate tooling, and setting up work-holding fixtures for both manual and CNC lathe and mill operations. Strong attention to detail and precision measurement skills are essential, as the role requires consistent first-piece and in-process inspection throughout the shift, quick learning of new part programs, and strong troubleshooting ability.

Prior lathe and mill machining experience is required.

• Comply with all safety and PPE requirements (eyewear, hearing protection, work shoes, uniform, etc.).
• Collaborate with plant staff to continually improve processes and workflows.
• Maintain punctuality and compliance with attendance and workplace policies.
• Complete production and inspection sheets accurately and on time.
• Weigh and process scrap according to established procedure.
• Routinely and frequently check parts produced against the quality control plan.
• Communicate clearly and consistently at shift changeover.
• Keep communication boards updated and followed accordingly.
• Ensure targets and metrics are visible and clear to all team members.
• Follow lunch break policy, including punching in and out for paid break time.
• Perform proper cleaning and maintenance of machine tools and work areas.
• Support down-time and scrap data collection.

Key Responsibilities & Job Duties

• Set up and operate manual and CNC lathes and mills to produce precision parts to blueprint and tolerance specifications.
• Read and interpret blueprints, engineering drawings, and GD&T callouts to determine machining sequence and setup requirements.
• Select, install, and adjust tooling, fixtures, and work-holding devices for each job run.
• Edit and optimize CNC programs (G-code) at the machine control as needed to correct offsets and improve cycle time.
• Perform first-article, in-process, and final inspection using precision measuring instruments (micrometers, calipers, height gauges, indicators, and CMM as applicable).
• Diagnose and correct dimensional or surface finish issues through tooling, speed/feed, or program adjustments.
• Machine components from a variety of materials, including steel, stainless steel, aluminum, and brass.
• Perform routine preventive maintenance on lathes, mills, and related equipment.
• Maintain accurate production, quality, and tooling records in the shop management system.
• Collaborate with Quality and Engineering on tooling changes, process improvements, and non-conformance resolution.
• Support new part run-offs, first-piece approvals, and production of prototype or short-run parts.
• Maintain a clean, organized, and safe work area consistent with 5S standards.
• Assist with training of junior machinists as needed.
• Perform other duties as assigned.

Required Qualifications

• High school diploma or equivalent; formal machinist training, apprenticeship, or associate degree in Machine Tool Technology preferred.
• 2–5 years of experience operating manual and/or CNC lathes and mills in a production environment.
• Ability to read blueprints, engineering drawings, and GD&T specifications.
• Proficiency with precision measuring instruments (micrometers, calipers, height gauges, dial/digital indicators).
• Working knowledge of Fanuc, Haas, Siemens, or similar CNC controls preferred.
• Basic G-code editing and offset adjustment skills.
• Familiarity with ISO or IATF quality system requirements as they apply to the machine shop.
• Ability to calculate speeds, feeds, and material removal rates.
• Comfortable with computer applications and willing to learn company software for job tracking and quality documentation.
• Ability to operate a forklift and overhead crane as needed.
• Excellent organizational and prioritization skills.
• Adaptable, self-driven, with strong troubleshooting and problem-solving ability.
