YAMASA Roller Burnishing is a method 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 precision 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's surface by rotation. In addition, a pressure is applied on the surface of the workpiece with a certain force thus the process of roller burnishing is achieved. The effects that occur at the point where a single roller is contact to the surface of the workpiece are as follows;
The contact of the roller to the workpiece is obtained by pressure. At this point, while the protrusions on the surface are being pressed, the gaps in bottom are filled up simultaneously. This process that we call as plastic deformation is repeated as long as the rotation, pressing and feeding continues. Therefore the smooth and bright surfaces are obtained.The feeding speed of roller and the pressure applied on the workpiece is defined according to the surface roughness which is required to obtain. The roughness values decrease by slowing down the feeding speed and increasing the pressure. On the contrary, while the pressure decreases and the speed of feeding becomes faster, the surface roughness values will increase.
