• Perform first-piece inspections and verify dimensions using precision measuring tools such as micrometers, calipers, bore gauges, and gauge pins.
• Run metrology checks on parts throughout the machining process to confirm dimensional accuracy and quality.
• Wash and clean completed parts to prepare them for packing and shipment.
• Safely operate an overhead crane or hoist to move casings and other large workpieces.
