Characteristics and performance of single roller burnishing tool

External groove single rolling type

Precise processing for external groove, such as external sealing ring of shafts and cylinder. Through changing rolling wheel shape, the tool may process external diameter with large size, prick, end, and R section.

Internal groove single rolling type

Precision inner groove rolling process for inner hole, used on lathe, such as inner groove sealing ring of oil cylinder.

By changing the shape of the roller, the groove of different shapes and the end face of inner diameter can be processed, such as inner sealing groove surface, R surface (inner R and outer R), inclined surface and so on for burnishing rolling.
