<p>PCT No. PCT/EP90/01168 Sec. 371 Date Feb. 14, 1992 Sec. 102(e) Date Feb. 14, 1992 PCT Filed Jul. 17, 1990 PCT Pub. No. WO91/02614 PCT Pub. Date Mar. 7, 1991.An insert for chip removing tools has a housing (10) that can be inserted in a recess in the base body of a tool. A threaded sleeve (16) is rotatably mounted in the housing (10) so as not to slide under the effect of an axial force. A machining blade insert holder (14) is non-rotatably guided in the housing (1) and is provided with an adjustment thread (21) that engages the threaded sleeve (16). The machining blade insert holder (14) is axially moved by rotating the threaded sleeve (16) and carries a reversible machining blade insert (12) on its head (18) that projects beyond the housing (10). In order to ensure a clearance free advance of the machining blade insert holder (14), an axial force exerted by a threaded clamping ring (78) on the threaded sleeve (16) is deviated by a clamping sleeve (60) with tapering front faces (62, 63) and two tapering bearing rings (66, 67) so that the threaded faces of the threaded sleeve (16) and of the machining blade insert holder (14) are pressed against each other by prestressing forces that act radially from the outside on the wall (50) of the threaded sleeve (16). In order to allow the threaded sleeve (16) to be elastically deformed, the threaded sleeve has in its threaded zone at least one radial through slot (46) which extends essentially in the axial direction.</p> |
