Kelkar, graduate in Production Engineering from VJTI is Managing Director of Grind Master Machines Pvt. Ltd. , pioneers and leaders in the field of Metal Finishing Machines. An energetic leader and innovator, who won CMTI-PMT Trust Award for Microfinishing in the year 2001 & is proud to be the World Class Supplier of Microfinishing Solutions.  \nPREAMBLE:  \nAs the world is progressing forward, Designers of Auto parts are resorting to varied and stringent surface finish parameters. In a bid to meet noise and pollution norms as well as decreased warranty claims, amundane finish like 0.4 Microns Ra which can be achieved by grinding, is suffixed by the word“Microfinished’ to ensure 200,000 KM Warranty from the same part !!!  \nTHE ARTICLE  \nMicrofinishing - The Process of Perfection for Auto Industry.  \nMachining has come a long way in the last one hundred years. Machine tools have become increasingly accurate, routinely achieving workpiece tolerances not even imagined fifty years ago. Finishes of critical bearing surfaces achieved by grinding, honing and polishing, while excellent processes, have been surpassed. Even lapping is no longer adequate in the manufacturing of today’s more fuel-efficient automobile and truck engines. While the perfect bearing surface will never be achieved, it is possible to come very close with Microfinishing.  \nProcess of Microfinishing with film backed abrasive was developed to achieve consistently uniform finishes faster and more efficiently than other traditional roll grinding and cylindrical finishers For years, grinding wheels and bonded abrasive stones, abrasive sheets – even slurries have constituted the usual means for resurfacing, dimensioning and polishing rolls and cylindrical parts. These traditional methods of roll finishing are typically slow and leave room for operator error.  \nFortunately, film-backed and flexible diamond abrasive offer fast, easy-to-use predictable alternatives.  \nMicrofinishing with contact wheel (Superfinishing)  \nFilm-backed abrasives provide predictable, consistent and repeatable performances every time for finishing operations. These film-backed abrasives enable you to quickly remove traverse marks and feed lines, eliminate chatter, follow existing geometry (including crowns) and consistently obtain sub- 1 micro inch Ra (.025 microns) or finer finishes on chrome, compressed paper, nylon, chilled iron, rotogravure, epoxy and polyurethane rolls and other non-roll surfaces.  \nMicrofinishing with non-resilient shoes  \nMicrofinishing process that employs rigid shoes instead of a contact roller or platen to support the abrasive film. The workpiece, such as a crankshaft or camshaft, is turned and oscillated between centers as shoes introduce the abrasive to the work interface. Fresh abrasive is incrementally indexed after each part is processed, resulting in uniform stock removal and finish, part after part.  \nMicrofinishing removes the damaged or amorphous layers to improve the surface finish and roundness of the part and, in many cases, can eliminate the need for an entire grinding operation.  \nCompared to conventional cloth and paper backings, film is a far more consistent substrate for the precise application of resins and micron-graded mineral. Film backings hold abrasive particles on top of the substrate, do not compress or lose particles in the backing.  \nCompared to conventional cloth and paper backings, film backings provide a superior, uniform surface to coat with micron graded minerals. The uniform application of abrasive mineral with a unique resin bond creates the ability to provide a more consistent, repeatable finish.  \nWHEN WAS MICRO-FINISHING DEVELOPED?  \nIn the mid 1930’s, it was discovered that automobiles transported to the west coast from Detroit, hada much higher rate of wheel bearing noise, such as chatter, clicking, etc. than did the cars sold closer to Detroit.
