The principle of inner hole rolling technique is the same as that of external rolling pressure. Because of the high productivity of roller burnishing process, honing is often replaced by rolling process. After the inner hole rolling pressure, the accuracy is within 0.01mm, and the surface roughness Ra is 0.16m or more. Rolling processing is very sensitive to the density, soft and hard uniformity of materials, and the uneven quality of materials can seriously affect the rolling quality. The rolling process can strengthen the surface of the workpiece and improve the surface hardness and wear resistance of the workpiece.
The Roller Burnishing Tools can be used in the ordinary machine tool with rolling device, which is not required for special equipment, so it is used more in production.
