Spring Loaded Abrasive Float Polishing is the method of polishing a work piece surface by using a sharp edged thin metallic material brush with alumina abrasives. It is a process by which material is precisely removed from a work piece to produce a desired dimension, surface finish, or shape. Surface finishes in the nanometer range can also be produced using this technique, which makes it an attractive method for materials processing. The process is different than conventional methods of polishing due to the fact that abrasives are much finer and the process is controlled efficiently. The machine will be applicable for nano level surface finish application as required in industries. The machine has the advantages as less cost, versatility, high accuracy and precision. The apparatus is designed for polishing number of work pieces simultaneously with high surface accuracy. The spindle was made according to dimensions of chamber. A fixture was made for resisting shocks and supporting the apparatus during polishing and springs are used for observing shocks and vibrations.
