Abstract

A knife ring machining tool for machining chips, with a knife ring comprising a crown of knife packets as well as two carrier rings carrying the packets, which rings are arranged on the ends of the knife packets. Each knife packet includes a knife that is inclined against the radial direction and whose cutting edge faces inward, with a rotor arranged coaxially with the knife ring and surrounded by the latter. The rotor includes a plurality of rotor blades that carry strip-shaped cleaving knives on the outer ends, which knives for their part run parallel to the rotor axis and extend over the width of the rotor. Each cleaving knife is fastened by screws to the associated rotor blade, while each screw connection comprises a wedge element that tapers outward in radial direction in a wedge shape, as viewed in a section vertical to the rotor axis.
