Centering is a necessary operation when assembling conveying equipment and various other peripheral devices to machine tools and production equipment. Centering work involves adjusting the position of connecting parts so that they are horizontal, vertical, or straight, and positioning the machine or equipment at the center. Shaft centering refers to the process of adjusting the position of two or more pieces of equipment such as motors and pumps so that they are aligned in the operating state when they are connected from one power shaft to the other.
