Job Description

Posted Wednesday, March 26, 2025 at 8:00 AM

The CNC Machinist III utilizes both analytical and technical knowledge to maximize efficiency through the operation of CNC lathe machines used in the manufacturing of various types of fittings. The CNC Machinist III is responsible for consistency in the operation and quality processes in accordance with product/process specifications and quality standards.

• Proficient with the set‑up and operation of CNC lathe machines according to blueprints, specifications, manufacturing orders, and work instructions.
• Selects proper material and tool holders and tooling for the job; prepares tool kits for incoming work orders; designates required tooling and modifies as needed to manufacture parts to specification.
• Maintains correct dimensions of parts while running the job using measuring instruments such as micrometers, comparators, calipers, and gauges; verifies the conformity of parts to blueprints/specifications during and/or after the run; replaces and aligns dull and broken cutting tools as required to maintain conformity of parts.
• Assists supervisors, mechanical engineers and planners with work organization to implement continuous improvement strategies, reduce cycle and down‑time for set‑ups; prepares the projects’ layout, tooling, inspection gauges, and material.
• Assists and trains less qualified machine operators as needed.
• Recognizes improper machine functioning and makes required adjustments; initiates and reports repairs for CNC machines as needed; performs minor troubleshooting and maintenance as required.
• Identifies, performs and troubleshoots operations and programming issues for improved product quality and tooling life; conducts and reports findings from tool life studies.
• Uses pass‑down logbooks and face‑to‑face turnover meetings to communicate status of machine(s) to include: times tools were last changed, maintenance issues that occurred during the shift, performance of the machine during the shift, and status of ongoing set‑up (e.g., if collets were changed, tooling at each position changed and aligned, program loaded, 1st article pieces complete and verified).
• Prioritizes workload and demonstrates the ability to measure and work to close tolerances.
• Represents factory/department in cross‑functional teams and/or in‑house committees.
• Relies on work instructions and pre‑established guidelines to perform the functions of the job.
