(57) Abstract The invention concerns a special device for producing by machining a multi- plicity of shaped bores or shaped external surfaces, such as squares, hexagons, el- lipses, polygons. This is done by superimposing a forced radial motion, produced by purely rolling-action elements (12, 13, 14, 15), on the rotational motion of a tool hol- der (3) in such a way that the cutting edge of a tool (23) inserted in the tool holder (3) follows the required path as the tool holder rotates. Unlike other methods, such as broaching and floating-tool broaching as well as erosion machining and milling, the device proposed enables shaped bores and external surfaces to be produced not only cleanly and to the required tolerances, but also very rapidly and simply. The form drilling and turning device proposed can be used on normal drilling and mill- ing machines and machining centres, as well as on turning machines with powered tools.
