• Thorough knowledge of blueprint reading, geometric dimensioning and tolerancing (GD&T), precision measuring equipment, and grinding principles.
• Understanding of grinding wheel selection, wheel dressing, feeds and speeds, work holding methods, and machine setup.
• Experience maintaining close tolerances and fine surface finishes is preferred.

• Follow setup sheets, engineering drawings, work instructions, and shop floor documentation to set up and operate OD and  machines.
• Install and true work holding devices, grinding wheels, fixtures, centers, chucks, and tooling required for each production run.
• Select, mount, balance, and dress grinding wheels based on material, dimensional requirements, and surface finish specifications.
• Use a hydraulic press to straighten shaft style parts as needed.
• Set machine speeds, feeds, wheel offsets, and grinding parameters to meet engineering specifications.
• Grind outside diameters, inside diameters, shoulders, faces, tapers, and other precision features while maintaining required tolerances and surface finishes.
• Verify the shop floor documentation and blueprint have the same revision level before beginning production.
• Perform first‑piece, in‑process, and final inspections using micrometers, bore gauges, calipers, dial indicators, height gauges, surface finish comparators, and other precision measuring equipment.
• Monitor grinding wheel wear and machine performance, making adjustments as necessary to maintain dimensional accuracy and maximize wheel life.
• Complete work orders in the order specified by the supervisor or shop scheduling system.
• Record labor, production quantities, scrap, downtime, and inspection results in the shop floor scheduling system.
• Perform routine operator maintenance including machine cleaning, lubrication, coolant maintenance, grinding wheel replacement, and routine inspections.
