Title of the Innovation: Abrasive Flow Finishing Machine

Brief About Innovation

Abrasive Flow Finishing Machine is used for smoothening the rough surfaces by subjecting the workpiece through a semisolid media and providing finishing touches on a Micro and Nano scale.  The machine can be applied to a wide range of finishing operations that will provide uniform, repeatable, predictable results.
