Grizzly G0763 Wheel Balancing, Tools Needed Qty, To balance the grinding wheel assembly

Wheel Balancing

An unbalanced wheel can result in a damaged wheel and poor finishes because the edge of the wheel does not contact the workpiece evenly.

Although the new wheel itself is generally balanced by the manufacturer, the addition of the sleeve and flange will require rebalancing. Additionally, the wheel can become unbalanced with wear.

Correctly balancing the wheel assembly will require trial-and-error and patience.
