Abstract (en)
A cutting head (1) for machinery suitable for carrying out machining by chip removal on materials comprises a main body in which one or more housing cavities (10) are obtained, each suitable for housing a respective cutter (11) and a clamping block (12). The cutter (11) is clamped between the clamping block (12) and a reference wall (4) of said housing cavity (10) and they have a geometry such as to provide a mechanical interference fit. Elastic means are provided in the housing, comprising an elastically deformable sheet element (21) with a cantilevered support portion located underneath the cutter (11) so that when said cutter (11) is in working position abutting on the reference wall (4) the elastically deformable sheet element (21) is bent downwards and thus exerts an action tending to push said cutter (11) radially outwards, in order to facilitate its extraction from the housing cavity (10). Further constructive expedient measures further facilitate and speed up the cutter (11) replacement operations.
