Abstract: A movable element for a damping system includes an absorbent mass arranged to be positioned in a housing. At least two adapted portions are arranged on a periphery of the absorbent mass. A plurality of elastic elements are arranged in the adapted portions and are designed to bear against an internal wall of the housing. The elastic elements have optimum damping properties in different variation ranges of at least one parameter. The present invention further relates to a damping system.

Abstract: A boring tool on a flange consisting of at least one tool holder and a flange, in which the tool holder is fitted with a means of gripping designed to engage the guiding and clamping assembly of the slide for guiding and holding the fastening flange, which is provided, in addition, with a device for limiting the travel of the tool holder or of the counterweight, or the positioning lug of a tool holder or of a counterweight can be put aside during placement a tool holder or a counterweight and returns automatically into position after this placement and in which each tool holder is fitted with a device for lubricating the cutting edge of the tool, coupled to the means of centralized lubrication of the flange. The tool is more particularly applicable in the field of numerically-controlled machine-tool accessories, tooling centers, cubicles, and flexible workshops.

Abstract: A tool holder (1) in the form of a boring head, a chuck, a milling cutting arbor, or the like, is equipped with a damping element (2) in the form of an elongated body that is arranged in an end housing (3) of the tool holder (1), with corresponding shape and size. The tool holder that is characterized in that it includes a device (4) for preventing excessive heating of the damping element (2). The tool holder is more particularly applicable in the field of numerically-controlled machine tool accessories, machining centers, and flexible cells and workshops.

Abstract: A damping tool holder, such as a boring head, a chuck, or a milling cutting arbor, integrates a damping device (2), in the form of an elongated body. The damping device (2) is housed in a mounting body (3), connected by one end to the tool-holder body (1) and having at its other end an end fitting (4) for mounting a tool, whereby the mounting body (3) is equipped with at least one lubricant feed pipe (32), emptying at its front end into the end fitting (4) for mounting a tool and connected at its other end to a circular groove (102) for distributing lubricant that is provided on the front surface of the tool holder (1).

Abstract: An axially adjustable tool holder, having a principal body (1)with attachment, in a recess (2) of which is slidably mounted a mobile part (3) for mounting a tool (4). The mobile part (3) cooperates with a ring for transverse adjustment (5), mounted in rotation on the extremity of the principal body (1)with the recess (2) and secured transversely to said extremity, by a ball bearing device (8), in the form of a sleeve with an interior thread (5?). The ball bearing device (8) presenting axial play of the ring for transverse adjustment (5), when the mobile part (3) is tightened, application of the proximal face (51) of the adjustment ring (5)against a corresponding distal external supporting flange (1?) of the principal body (1). The mobile part (3) being locked in working position, after adjustment, by a device for tightening (6) by traction cooperating with a part (7) of the mobile part (3).
