Abstract:
1. A method of magnetic-abrasive machining of a flat part, comprising the steps of supporting the flat part so that it has an upper surface and a lower surface; generating a magnetic field by magnetic means located under the lower surface of the flat part; placing a magnetic-abrasive powder on the upper surface, so that the flat part is located between said magnetic means and said magnetic-abrasive powder and the magnetic-abrasive powder is attracted to the upper surface of the flat part by said magnetic means at a side of the lower surface of the flat part; and providing a movement of the flat part and the magnetic-abrasive powder means relative to one another so as to machine the upper surface of the flat part which carries only the magnetic-abrasive powder and is therefore not obstructed but is open for observation and supply of the magnetic-abrasive powder.
