Abrégé

A tool holder for a machining tool includes a cooling means for a compressed air blowing tool and a device for cooling air compressed by a vortex tube device. The tool holder is generally cylindrical and the vortex tube device advantageously includes a plurality of vortex tubes placed annularly around the axis of the cylinder and the cold air outputs of which are directed at the tool held by the tool holder.

Abrégé

The invention concerns a method and device for adjusting the fitting depth of a tool in a tool-holder, in particular in a tool-holder to be banded. The method is characterized in that it consists in performing a prior calibration of a sensing assembly (2) by positioning a sensing slide (4) of said assembly (2) into a bore (V) of a calibrating support (1) and by re-setting a viewing means of said sensing assembly (2), then in positioning the sensing assembly above a tool-holder and moving the adjustable stop of said tool-holder towards the sensing slide (4), so as to determine a travel thereof corresponding to the required fitting depth. The invention is applicable in the field of the environment of machine-tools, more particularly comprising tool-holders to be banded.

Abrégé

The invention relates to a tool holder (1) for a machining tool, comprising cooling means for a compressed air blowing tool and characterized in that the tool holder includes a device for cooling the compressed air by a vortex tube device. If the tool holder is generally cylindrical, the vortex tube device advantageously includes a plurality of vortex tubes which are placed annularly around the axis of the cylinder and the cold air outlets of which are directed at the tool held by the tool holder.

Abrégé

The present invention relates to a tool holder, such as a reaming head (1), or a milling arbor, provided with a damping means (2) in the form of an elongated body, which is arranged in an end compartment (3) of the tool holder (1), which compartment is of appropriate shape and size, and closed at its end by a body (4) for receiving a reaming head or by a milling element. Tool holder characterized in that the damping means (2) is of the type presenting only radial absorption, and it is provided with at least one elastically deformable means (5), at least close to each end, where said elastically deformable means (5) extend between the envelope of the damping means (2) and the wall of the compartment (3) of the tool holder (1), and are clamped between the wall of the compartment (3) and the damping means (2), and where the ends of the damping means extend in the compartment (3) without stress. The invention is applicable more particularly in the field of accessories for machine tools, with digital control, machining centers, flexible cells and workshops.
