TRUING AND DRESSING. When a new wheel is installed on the grinder, it must be trued before use. The cutting surface of a new wheel will run out slightly due to the clearance between the wheel bore and machine spindle (Figure L-51). Truing a wheel will bring every point on its cutting surface concentric with the machine spindle.

In operation, the grinding wheel and regulating wheels are moved back for loading clearance. Once loaded, the shaft is clamped between centers. The wheel head slowly brings the workpiece up to its programmed rotational speed. Next the grinding wheel is infed to the workpiece. In this operation the regulating wheel is not involved.

The pad diameter is large. This means that it is more aggressive. The smaller the pad size, the less aggressive it will be. Unlike orbital polishers, an angle grinder increases in velocity towards the outer edge of the pad. In addition, when you change the pad size, it has a low impact on the performance and behavior of the tool.
