Nanometric Finishing of Flat Surfaces Using Magnetic Field

The need for mirror-finished surfaces has grown rapidly in recent years. This is due to improvements of new products application in high technology industries. New requirements urge new production methods. One of which, in the field of machining technology, is Magnetic Abrasive Finishing. This results in surface roughness of materials in the order of sub-micron and nano level. The technology is based on the magnetic field force, which is exerted on the abrasive powder and runs the powder tool on the surface of work piece. The process was applied to flat planes. A special apparatus was designed and made for implementation of experiments. Many properties of different factors affecting this process were examined and their influence on the surface roughness was cleared.
