Abstract (en)

The present disclosure relates generally to the field of surface finishing operations, more particularly to micro-finishing systems and processes. The micro-finishing system and process of the present disclosure is configured to perform surface finishing operation on a work-piece. The micro-finishing system comprises: (i) a micro-finishing film having a layer of abrasives which is configured to be rubbed against the work-piece, (ii) a contact tooling which is configured to provide support to the micro-finishing film, and (iii) ports which are configured within the contact tooling strategically to reduce heat and frictional losses generated due to rubbing of the layer of abrasives against the work-piece by a minimum flow of coolant at the desired location. The ports are typically drilled holes.
