Abstract:
A chuck for accommodating a collet chuck, comprising a housing and a chucking tool seat that is assigned to the housing. The chucking tool seat is embedded in the housing as a separate part via an intermediate filling that is made of polymer concrete for connecting the chucking tool seat and the housing. This design has improved properties regarding damping and the total weight while flat sub-areas that are composed of individual guiding plates can additionally be used as clamping areas of the chucking tool seat. Thus a pyramid-type joint is obtained, which could previously be created with the required precision only by using a lot of effort when producing the same from solid material.

Abstract:
The invention provides a clamping system (1) for a rotary tool (70), for example a milling cutter or drill. The clamping system (1) includes a base element (10), a collet (30) and a clamping nut (50), said clamping nut (50) friction-locking the rotary tool (70) within the base element (10) with the collet (30). In order to avoid a relative rotation of the base element (10) and the collet (30), the clamping system (1) has a form locking anti-twist protection which blocks a rotation of the collet (30) relative to the base element (10).

Abstract:
A chuck for accommodating a multipart collet for clamping a workpiece in place has a housing with a collet receptacle having a guide device and guide surfaces. The collet is movable on the chuck in the axial direction. The guide device has balls as rolling elements on the guide surfaces, of which a multiplicity are continuously arranged on a rolling element holder. They are movable together with the latter in the guide device from an initial position into the chuck. A restoring device is provided for the rolling element holder, with a direction of action out of the chuck, in order to move the balls back into the initial position when no collet is in the chuck.
Abstract:
A cutting tool chuck holds a collet so as to be easily changed. In the cutting tool chuck, a fastening collar (12) is screwed on a chuck sleeve (14). The fastening collar (12) is provided with an internal guide groove (24), deep recesses (24a) formed in a side surface of the guide groove (24), and shallow recesses (24b) formed in the same side surface. A drive shaft (16) is axially slidably fitted in the chuck sleeve (14) with end portions (26a) of a drive shaft control member (26) laterally projecting from the drive shaft (16) and fitted in the guide groove (24). A collet (20) is detachably mounted on the front end of the drive shaft (16). The fastening collar (12) is turned so as to position the end portions (26a) of the drive shaft control member (26) at positions on the side surface of the guide groove (24) other than the deep recesses (24a) to hold the collet (20) on the drive shaft (16). The fastening collar (12) is turned so as to make the end portions (26a) of the drive shaft control member (26) drop into the deep recesses (24a) formed in a side surface of the guide groove (24) so that the drive shaft (16) is moved forward to release the collet (20). Thus, the collet (20) can be fastened to and can be released from the drive shaft (16) simply by turning the fastening collar (12).
