ABSTRACT:
The invention relates to a multiple cutting edge rotary tool having a radial individual adjustment of each cutting edge or having a central adjustment for all cutting edges together. The multiple cutting edge rotary tool used for machining has a number of holders that have, in the front part, cavities for accommodating cutting plates and have, in the area between their ends, a hole for passing through a fixing device with which each holder can be fixed to a support. The holder, on its portion that supports the cutting plate, can be elastically deflected in relation to a support by means of an adjusting device. In addition, the holder is provided with an opening and forms a parallel spiral spring arrangement whereby the cutting plate, during its adjustment, is essentially subjected to a parallel displacement with regard to the cutting edge. The adjusting device is provided in the form of a central adjusting screw which, as an axially adjustable differential screw, retains, by means of a lifting motion of the differential screw, the holder in a manner that permits it to be radially displaced in relation to its support and without play. The retention of said holder is effected by adjustable pressure pieces that are supported on parts of the adjusting screw.
