Things You'll Need:
- Eye protection
-
Step 1
Adjust the height valve, located on the grinder head, so that the grinder blade is as far from the magnetized palette as possible.
-
Step 2
Place the block of metal to be ground on the magnetized palette.
-
Step 3
Toggle the palette lever, located near the control panel and typically marked by a red dot. This will magnetize the palette and keep your metal block from moving.
-
Step 4
Readjust the grinder height so that it is approximately 2 inches from the surface of the metal block. You do not want to start the grinder with it touching the metal block, as the grinder wheel could be damaged as it starts to spin.
-
Step 5
Activate the grinder. This is typically done by turning the ignition key, then pressing the green- or red-colored "Start" button. The grinder will begin spinning and lower itself in a pre-set back-and-forth pattern, rotating a half-inch back and forth until it makes contact with the surface of the metal block.
-
Step 6
Watch the surface of the metal. If you leave the block in place, the grinder will eventually grind it to dust. Typically, a bench grinder is used to grind away 1/16 of an inch of metal at most. When the metal surface is smooth and polished, you should turn off the machine and remove your piece.
