    Abstract: A process of grinding a pre-ground part wherein the method includes the steps of: providing a pre-ground part containing a bore, and the pre-ground part having an exterior surface with one or more to-be-ground exterior surface regions; positioning a loading tool within the bore of the pre-ground part; exerting a loading tool load on the loading tool which in turn exerts a part load on the pre-ground part; removing material from the one or more to-be-ground surface regions of the pre-ground part when under the part load to form an as-ground part; and unloading the part load from the as-ground part.

    Abstract: In one aspect, tool holders employing axial sleeves and dampening elements are described herein. Tool holders described herein define a central longitudinal axis and comprise a tool holder body having a connector portion and a holder portion. The connector portion is structured to engage a rotary machine and the holder portion is disposed opposite the connector portion and has an inner diameter surface comprising a plurality of axial grooves. Tool holders described herein further comprise a tool receiver structured to receive at least a portion of a cutting tool, the tool receiver having an outer diameter surface comprising a plurality of axial grooves. The tool receiver is mounted in the holder portion so as to align the axial grooves of the inner and outer diameter surfaces and define axial sleeves filled with dampening elements.

    Abstract: Collet chucks are described herein having design and architecture for minimizing and/or mitigating collet misalignment during rotary tool coupling operations. For example, a collet chuck comprises a housing for connection and rotation with a spindle about an axis of rotation, wherein the housing defines a socket for receiving a collet. The collet comprises a nose end engaging the socket and a second tapered end engaging a locknut assembly.

    Abstract: A tool shank for use with a cutting insert in a rotary cutting tool includes a body having, and adapted to be rotated about, a central longitudinal tool axis, the body having a tip portion structured to receive at least a portion of the cutting insert therein. The shank also includes a pair of chip flutes formed in the body and a pair of recesses, each recess bordering a respective chip flute. Each recess includes a rim portion extending perpendicular to the tool axis and a bearing surface extending at an incline relative to the tool axis. Each rim portion is adapted to engage a corresponding surface on the cutting insert. Each bearing surface is adapted to engage a corresponding bearing surface on the cutting insert in a manner such that the cutting insert is pulled against the body when the rotary cutting tool is rotated about the tool axis.
