  • Publication number: 20090304466
    Abstract: The invention relates to a cutting tool for machining processes, in essence composed of a clamping holder with a recess for accepting a support plate and with a cutting plate secured on the support plate by way of a clamping claw. It is proposed, for secure fastening of the cutting plate on the clamping holder, that an interlocking tongue-and-groove connection is used for positioning of the cutting plate on the support plate.

  • Publication number: 20040256608
    Abstract: The invention relates to a metal cutting tool essentially comprised of a supporting tool (13), which has a recess for accommodating a cutting plate (10). The cutting plate (10) is provided with a clamping trough (11), which is held in the supporting tool (13) by a clamping claw (16). The clamping claw (16) is fixed against the supporting tool (13) by a clamping screw (17). A pressure piece (14) is placed on the clamping claw (16) and its underside facing the cutting plate (10) is provided with a cam, which is in contact with the clamping trough (11), and the clamping claw (16) pulls the pressure piece (14) toward the clamping screw (17). According to the invention, the clamping trough (11) is provided with a circular shape and has a spherical or circular elevation (12) in the center. The cam on the pressure piece (14) consists of a circular ring (21), which is adapted thereto and rightly engages in the clamping trough (11) while surrounding the elevation (12).

  • Patent number: 5139371
    Abstract: A clamp for circular cutting tools (2) has a bearing bore (6) at the clamp head (5) in order to support a cup-shaped insert (7). The receptacle (9) of the cup-shaped insert (7) is elastically deformable and has a recess configured as a truncated hollow cone and the centering profile (3) of the circular cutting tool (2) is configured as a truncated cone. The convergin cone angle of the recess in receptacle (9) is smaller than the cone angle of the centering profile (3). Several cuts (10) separate the receptacle (9) in spring segments (11). The bottom (12) of the recess has a larger diameter than the contact surface (13) of the circular cutting tool (2). It is provided with a circular groove (14) running along its periphery.
