Centerless OD Burnishing Machines
(External Centreless Burnishing Machine)
| Roller Burnishing is a cold working Process which
produces a fine surface finish by the planetary rotation of hardened
rolls over a bored or turned metal surface. Roller Burnishing involves
cold working the surface of the work piece to improve surface structure |

|

The COBUM series of roller
burnishing machines are designed to give a mirror - like finish with a
tough, work hardened, wear & corrosion resistant surface. The
burnishing is done by Centerless Method
