  • Device for connecting two tool parts
    Patent number: 7066693
    Abstract: The invention relates to a device for releasably connecting two coaxially aligned tool parts (1, 2) which can be axially pressed against each other on separating surfaces (36, 38) that face each other with a clamping device. According to the invention, at least one of the separating surfaces (38) is divided into several axially rigid and torsionally soft bearing segments (50) which are spaced in a peripheral direction, in order to dampen the torsional oscillations that occur during the work process and reduce noise.
    Type: Grant

  • Machine reamer and reaming head for a machine reamer
    Patent number: 6896450
    Abstract: The invention relates to a machine reamer, with a shaft-like base body (10) and a reaming head (12), projecting axially from the front face of the base body. According to the invention, the reaming head is in the form of a one-piece exchangeable cutting tip (12), which may be chucked into a tip seat (14) on the front face of the base body (10), in a coaxially self-centering manner, in order to maintain a high precision coaxialism, despite low material and construction requirements.
