Abstract

An arrangement comprising a bore-type hobbing cutter and a holding arbor wherein the bore of the hobbing cutter has ground cylindrical centering surfaces at its ends and the arbor has complementary seating surfaces and wherein the hobbing cutter is axially chucked on the holding arbor by means of axial chucking means, where a preferably sleeve-shaped cage is disposed between centering surfaces and has a thickness which is smaller than the radial distance between centering and seating surfaces, and has an outside diameter which is smaller than the inside diameter of centering surfaces, the cage supports, in a circumferential direction, at least a number of prechucking elements, which are preferably metallic and are in contact with the associated centering surface and the seating surface, and said diameter and the distance between the contacting points or contacting lines of prechucking members are slightly larger than the radial distance between centering and seating surfaces.
