Roller burnishing medhod 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'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. There are too many advanteges as below : The surfaces in quality of rz< 1¦m can be obtained. It is possible to catch the desired size easily and rapidly. The process is completed by one pass. The process time is very short. The roller burnishing process hardens the surface in the same time. It ensures the processed surface to become stronger, more brilliant and slippery. Roller burnishing process makes the wear of the workpiece difficult and other components which work on the workpiece surface. It saves time, money and energy. No sawdust and residues occurr. No noise and damage to the environment. It requires low lubrication and cooling. Yamasa roller burnishing tools and machines provide surface hardness and calibration (measurement accuracy) beside of burnishing. Because of the high processing power and speed ability it provides time savingthese are the preference causes for the serial production. . These machines and tools are capable to process all kinds of metallic materials with 1400 n/mm¦ tensile strength and hardness up to max. 42-45 hrc. Min. Dia. 5 up to 350 mm.
