[0040] 1) Place the wheels to be ground on the conveyor belt at equal intervals and automatically transport them to the product area to be ground (i.e. the position where the wheel chuck clamps the wheel). The conveyor belt is controlled by a stepper motor, and each time it moves, it can transport the next wheel to be ground to the product area to be ground;
