Abstract: Some embodiments are directed to a fixing apparatus that includes a threaded adaptor, an arbor having a flange portion and a shaft portion, and a draw cylinder disposed such that rotation of the threaded adaptor moves the draw cylinder in axially upward and downward directions. A collet can be disposed around a periphery of the arbor so as to be coaxial with the draw cylinder, such that movement of the draw cylinder in the axially downward direction causes the draw cylinder to contact the collet and thereby cause the collet to also move in the axially downward direction. The collet can include axially extending channels that define fingers therebetween and interior coaxial surfaces that are configured to communicate with exterior coaxial surfaces of the arbor such that axially downward movement of the collet moves the fingers in a radially outward direction to thereby increase an exterior diameter of the collet.

Abstract: A clamping device for releasably holding a tool holder shank is formed with an engagement bore in a rear end, and includes a housing having a bore in a forward end for receiving the tool holder shank, a drawbar reciprocally movable inside the housing and which in a forward end is provided with engagement means arranged to engage with an engagement formation inside the engagement bore of the tool holder shank, and which is formed with a drawbar aperture extending through the drawbar in a transverse direction of the same, and a cam shaft extending through the drawbar aperture. The cam shaft includes three cam formations and more precisely first and second spaced apart cam formations, which are journalled in seating apertures in the housing on opposite sides of the drawbar, and an intermediate third cam formation located between the first and second cam formations and positioned within the aperture of the drawbar. The drawbar is insertable into the bore from the forward end.
