The Magnetfinish(MF) technology is a new mechanical process for technical surfaces. The workpiece is positioned in a magnetic field created by a magnetic disk. The gap is filled with magnetizable processing powder. The powder works during the process as an elastic tool. The hardness of this "tool" may be adjusted by the variation of definite technological parameters of the process. Surfaces will be smoothed till a roughness of Ra = 0,02 micrometers. Edges will get an exactly defined and reproducable radius between 3 and 50 micrometers. With this technology it is not only possible to process magnetic materials (e.g. HSS) but also light magnetic (e.g. carbide) and non-magnetic materials (e.g. Cermet).
