• Able to read blueprints and understand GD&T callouts where applicable.
• Experience working with carbon steel, brass, stainless steel, aluminum, or similar bar stock materials.
• Ability to work safely around rotating bar stock, cutting oil, chips, and moving mechanical components.

Preferred Qualifications

• Experience with 6-spindle or 8-spindle Acme-Gridley machines.
• Experience with Greenlee, New Britain, Davenport, Wickman, or similar screw machines.
• Ability to grind and touch up form tools, cut-off blades, drills, and special tooling.
• Experience with high-volume production, short-run changeovers, and customer-specific quality requirements.
