Abstract
A fly-cutter milling machine for the simultaneous milling of a plurality of profiled structures developed in the form of grooves, surfaces or the like in rotating workpieces by means of a fly cutter which protrudes radially outward on a rotating tool holder and which plunges through the cross section of the workpiece with a speed corresponding to the conditions of the fly-cutting, the speeds of rotation of tool holder and workpiece being in a ratio determined by the desired profiled structure, and in order to increase the range of use of the fly-cutter milling machine, the speed of rotation of the fly cutter over the emerged path differs from that over the plunge path.
