Core Responsibilities

Primary Functions

Operate multi-axis CNC milling machines and routers to precisely shape raw wood blocks into complex guitar bodies and necks based on digital models and programs.
Interpret and execute work from detailed engineering blueprints, CAD drawings, work orders, and specification sheets to ensure all components meet strict dimensional tolerances.
Select, inspect, and prepare various species of tonewoods, demonstrating a deep understanding of their unique grain patterns, densities, and acoustic properties for optimal results.
Perform intricate secondary machining operations using manual equipment like pin routers, drill presses, and specialized jigs to create pickup cavities, control pockets, and neck joints.
Set up, calibrate, and perform routine preventative maintenance on all assigned CNC machinery, including tool changes, offset adjustments, and fixture alignments to ensure peak performance and accuracy.
Conduct rigorous in-process and final quality control inspections on all machined parts using precision measuring instruments such as digital calipers, micrometers, radius gauges, and custom templates.
Troubleshoot and resolve machining issues in real-time, diagnosing problems related to programming, tool wear, material inconsistencies, or machine function to minimize waste and downtime.
Execute detailed hand-sanding and final shaping operations on machined components to achieve specified contours, smooth transitions, and a flawless surface ready for the finishing department.
Manage and organize a large inventory of cutting tools, fixtures, and jigs required for various production models, ensuring they are in good condition and readily accessible.
Read, comprehend, and execute G-code and M-code programs, with the ability to perform minor edits at the machine control to optimize tool paths or adjust for material variations.
Perform critical fretboard manufacturing tasks, including precision fret slotting and radius sanding, to ensure accurate intonation and superior playability.
Operate traditional woodworking equipment, such as table saws, band saws, jointers, and planers, for the initial preparation and dimensioning of raw lumber stock.

Secondary Functions

Collaborate closely with engineering, design, and assembly teams to provide valuable feedback on part manufacturability and contribute to new product development and prototyping efforts.
Maintain a safe, clean, and highly organized work environment by consistently adhering to all company safety protocols, 5S principles, and best practices for shop cleanliness.
Diligently document production data, including cycle times, part counts, and quality control findings, to support process improvement and operational efficiency analysis.
Assist in the development, testing, and implementation of new machining processes, tooling, and fixtures designed to enhance production efficiency, quality, and overall capability.
Actively participate in continuous improvement and lean manufacturing initiatives aimed at reducing waste, streamlining workflows, and optimizing the entire production process.
Monitor machine performance during operation, listening for unusual sounds or vibrations that could indicate a potential mechanical issue, and report findings to maintenance.
Ensure all finished components are carefully handled, deburred, and transported to the next stage of the production process without sustaining any damage.
Provide guidance, mentorship, and on-the-job training to junior machinists or apprentices, sharing knowledge of best practices, machine operation, and quality standards.
