The magnet finishing procedure is a new form of mechanical treatment of the edges and surfaces.
The workpiece is positioned in the magnetic field of one or two tooling heads. The space between the workpiece and magnetic head is filled with a magnetic, abrasive grinding powder. The magnetism performs the function of holding the powder in place, while the abrasive feature performs the workpiece grinding function.
Through the use of permanent magnets a particularly intensive powder adhesion is obtained, which makes a high operating powder pressure possible on the surface being worked on. Accordingly, this feature results in a particularly high cutting productivity.
Different powder types work like a flexible tool, whereby the grain size, powder impact and the operating time are relevant for the result. Defined material points can be reduced down to a roughness of Ra = 0.2 µm and Rz = 0.8 µm. Outside radiuses receive during processing with the magnet finishing procedure a radius between 3 and 50 µm with a remarkably smoothed surface.
The SECKLER deburo magnetfinish system consists of a magnet finishing unit, built into a SECKLER modulo cell with powder supply, flushing system, demagnetizing section and an ultrasonic wash station. The SECKLER deburo magnetfinish can be combined with the outstanding, proven SECKLER deburo brushing technology, customized machines and the SECKLER handling technology.
