The machine's condition and rigidity are crucial factors, allowing for the use of softer wheels for specific tasks. Wheel speed is significant; running a rigid wheel at slower speeds can emulate the characteristics of a softer wheel. Operating a grinding wheel at the manufacturer's recommended speed is generally advisable.
