Planer Machine Tool Using Magnetic Levitation

Abstract: The invention relates to the machine tools such as planers. The existing planers use one cutting stroke and another idle return stroke. This reduces efficiency of planer. They also use large mechanical effort to operate the planer and consume more time in metal-cutting-operations. The present invention uses magnetic levitation principle by providing horizontal and vertical permanent magnets and electromagnets on opposite surfaces of different parts of planers used while carrying out cutting and propulsion processes, thereby reducing required mechanical effort. The invention leads to lesser maintenance cost due to less wear and tear by avoiding physical contacts between tool-posts and their guideways happening because of effect of appropriate magnetic fields. The invention reduces machining time by using plurality of cutting tools and eliminating idle strokes. This invention provides uniform cutting speed and enables machining of plurality of identical workpieces at a time. The invention is useful in mechanical workshops where metal-cutting-processes are used for creating flat surfaces on work-pieces.
