In addition to the Shop Orientation, you must receive Proficiency Training from Shop staff before using the bench grinders.
Grinders shape metal via abrasion. Typical tasks include sharpening tools, removing burrs, and chamfering edges.
Only grind ferrous metals like steel and cast iron. DO NOT grind non-ferrous metals like aluminum, copper, brass, or bronze, as they will clog and damage the wheels.
The Shop typically provides aluminum oxide grinding wheels in a range of grits from 50 to 100.
