Core Responsibilities

Primary Functions

Set up, program, and operate multi-axis CNC milling machines and lathes to produce intricate jewelry components from precious metals like gold, platinum, and silver.
Interpret and work from detailed 2D technical drawings, blueprints, and 3D CAD models to ensure manufactured parts meet precise design specifications.
Select and install appropriate cutting tools, collets, and fixtures for each specific job, making adjustments as necessary to optimize performance and material usage.
Write, edit, and troubleshoot CNC programs directly at the machine interface (G-code, M-code) to refine machining paths and ensure flawless execution.
Utilize CAM software (such as Mastercam, RhinoCAM, or Powermill) to generate efficient toolpaths for complex surfaces and geometries unique to jewelry design.
Conduct first-piece and in-process quality inspections using high-precision measuring instruments, including digital micrometers, calipers, and optical comparators.
Perform meticulous visual inspections of machined parts under magnification to identify and correct any surface imperfections, burrs, or tooling marks.
Machine extremely tight tolerances, often measured in microns, required for settings, clasps, and other functional jewelry mechanisms.
Manage the machining of new product prototypes and samples, providing critical feedback to designers and engineers on manufacturability.
Monitor machine operations closely, listening for signs of tool wear or mechanical issues, and making proactive adjustments to prevent defects.
Develop and fabricate custom jigs, fixtures, and tooling as needed to support unique or challenging production runs.
Execute complex machining operations such as micro-milling, engraving, and turning on small, delicate workpieces without causing damage or deformation.
Maintain a comprehensive log of all production runs, including setup details, cycle times, tool life, and any non-conformances for future reference and process improvement.
Take full ownership of the part quality from the initial cut to the final hand-off, ensuring each component adheres to the highest standards of luxury craftsmanship.

Secondary Functions

Perform routine and preventative maintenance on CNC machinery, including cleaning, lubrication, and coolant management, to ensure optimal performance and longevity.
Collaborate closely with the CAD design and bench jewelry teams to troubleshoot design challenges and optimize parts for efficient manufacturing.
Contribute to the continuous improvement of machining processes, suggesting new techniques, tooling, or programming strategies to increase efficiency and quality.
Maintain a safe, clean, and organized work environment in the machine shop, adhering to all safety protocols and procedures.
Assist in managing the inventory of raw materials, cutting tools, and other machining consumables.
Support the research and implementation of new machining technologies, equipment, or software to enhance a company's manufacturing capabilities.
Document best practices and standard operating procedures (SOPs) for various machining tasks to aid in training and consistency.
