Roller Burnishing Tools almost can be used for any type of ID or OD burnishing, but for some special situation, you should to know below:
Thin wall workpiece, due to there has a thin wall, it is easy to deform under the action of clamping force. Also under the action of burnishing force, it is also easy to produce vibration and deformation, thus, the dimensional precision, surface roughness, shape precision and position precision of the workpiece are affected. So BRT will let you know how to burnish thin wall workpiece in cold rolling forming, it is important for burnishing industry of thin wall workpiece.
Roller burnishing process is to use roller pin to burnish inner part or outer part of workpiece, make it densified, so the diameter of the workpiece will be change between before and after processing (the inner diameter will expand, and the outer diameter will decrease). In order to workpiece can be able to bear the burnishing pressure, the wall thickness should be higher in the burnishing part (at least 20% of the inner diameter).
And there are also several different treatments: 1. Reducing the burnishing amount; 2. Using fixture supports the outer circumference of workpiece; 3. Burnishing workpiece before turning thickness wall of workpiece.
