This method is for to make the workpiece, which has passed through the pre-machining, smooth and hard. It is possible to process any kind of metallic material by using this method. The roller burnishing is done by contacting of the rollers on the surface of the workpiece by the help of a precious mechanism. When such a contact is obtained, the workpiece or the tool turns at a specified speed, then the rollers go forward on the workpiece&＃39;s surface by rotation. In addition, a stress is applied on the surface of the workpiece with a certain force thus the process of roller burnishing is achieved.
