Abstract
A compressor pulley having a partially cold forged base of improved strength and a bridge of improved strength is easily manufactured. Metal is heated to a predetermined temp and then hot forged into a pulley shape. A piercing step then forms a through hold in a center portion of the pulley. The heated pulley is then cooled to room temperature. Then the pulley is rough guided. A partial cold-forging step forges the base at room temperature. A slot is then pierced in the base portion. During a finishing step, groove working and grinding are performed on a surface of the pulley.
