Perform precision smoothing, sharpening, polishing, or grinding of metal objects.

Attach workpieces to grinding machines, then form specified sections and repair cracks, using welding or brazing equipment. Compute numbers, widths, and angles of cutting tools, micrometers, scales, and gauges, and adjust tools to produce specified cuts. File or finish surfaces of workpieces, using prescribed hand tools. Fit parts together in preassembly to ensure that dimensions are accurate. Inspect, feel, and measure workpieces to ensure that surfaces and dimensions meet specifications. Monitor machine operations to determine whether adjustments are necessary; stop machines when problems occur. Select and mount grinding wheels on machines, according to specifications, using hand tools and applying knowledge of abrasives and grinding procedures. Set up and operate grinding or polishing machines to grind metal workpieces such as dies, parts, and tools. Straighten workpieces and remove dents, using straightening presses and hammers. Study blueprints or layouts of metal workpieces to determine grinding procedures, and to plan machine setups and operational sequences. Turn valves to direct flow of coolant against cutting wheels and workpieces during grinding. Dress grinding wheels, according to specifications. Duplicate workpiece contours, using tracer attachments. Inspect dies to detect defects, assess wear, and verify specifications, using micrometers, steel gauge pins, and loupes. Perform basic maintenance, such as cleaning and lubricating machine parts. Place workpieces in electroplating solutions or apply pigments to surfaces of workpieces to highlight ridges and grooves. Remove and replace worn or broken machine parts, using hand tools. Remove finished workpieces from machines and place them in boxes or on racks; set aside pieces that are defective.
