Since the scarf processing is carried out using one speed difference, the scarf #1jIl surface can be formed as the center of the roller becomes deeper and gradually becomes shallower as it reaches the outer layer, and a smooth scarf groove surface with no unevenness can be obtained. First, due to automation, scarfing can be performed in an extremely short time, and remarkable effects and effects are exhibited, such as the scarfing can be carried out in an extremely short time, and conventionally skilled techniques are completely required using the palm of the hand.
