Abrégé

The present invention relates to a rod-shaped tool holder (1) having a length (I) for the attachment of at least one machining cutting bit (2). The tool holder (1) is configured for being clamped at a first end (4) and has a second free end (3) and optionally a secondary support between the clamping point (4) and the at least one cutting bit (2). In operation, the tool holder oscillates in higher order bending oscillations about at least one node (6) located on a curvilinear axis (x) extending from the first end. The at least one cutting bit (2) is positioned substantially at the node (6) in a distance from the free end (3), towards the first end (4).

Abrégé

The present invention is related to a device for internal chips cutting machining in a bore with a unit for breaking up chips by internal chips cutting machining in the bore. The device comprises a principal element (2) with a longitudinal axis and with at least one movable cutter head (1) with a cutter (3) that can be moved essentially perpendicular to the longitudinal axis of the principal element (2). The device comprises a mechanism for linear motion. A nozzle (9) for flushing of the cutter fluid on the cutter (3) is located onto and can be moved together with the cutter head (1). A fluid duct (5) is in connection with the nozzle and with a source for cutter fluid at high pressure.

A damper includes at least one substantially longitudinal damping body with two end surfaces and one substantially longitudinal surface between. The damping body is placed in a substantially longitudinal cavity, which includes a cavity surface, with a damping fluid that includes a liquid and a gas. At least one of the cavity surface, end surfaces or longitudinal surface is broken, and the damping body can pulsate in the cavity when the damper is in operation.

Abrégé

The present invention concerns a damper for damping vibrations. The damper includes at least one substantially longitudinal damping body (1) with two end surfaces (21, 22) and one substantially longitudinal surface (20) between these. The damping body (1) includes a longitudinal direction (a) and a transversal direction (t) and is places in a substantially longitudinal cavity (15) with a damping fluid, wherein the cavity (15) defines at least one cavity surface (14) and the damping body (1) defines at least one damping surface. The damping fluid includes a proportion of liquid and a proportion of gas and either the cavity surface (14) or the damping body surface or both are broken to promote formation of foam in the damping fluid in operation.

Abrégé

The present invention concerns a system with a container and a tool holder (20) with two ends (21, 22). One of the ends of the tool holder (20) is adapted for being secured to a machine tool and the other end is adapted for attaching a cutting edge or a cutting edge carrying unit. The tool holder (20) includes an internal cavity (23) surrounded by a cavity wall. The cavity (23) accommodates the container (1). One end (21) of the cavity (23) is adapted for connection to a supply for a cooling medium and the other end (22) is connected to an outlet for cooling medium. The cavity (23) furthermore includes an opening (25) for installation of the container (1). At least one gap for leading the cooling medium is formed between the container (1) and the cavity wall. Furthermore, it is described a container (1) for installation in a machine tool, and use of the container for accommodating one or several sensor for measuring parameters or for receiving a damping system.
