Hydraulic expansion chuck with a basic body, with an expansion bush which is received in the basic body and defines a reception space for a tool to be clamped, and with a pressure chamber which is delimited between the expansion bush and the basic body. A securing pin extends through the basic body and the expansion bush into the reception space. Also broadly contemplated herein is a method for producing a hydraulic expansion chuck via: providing a basic body with a blind hole, into which an internal thread is cut. An expansion bush is then soldered into the basic body. Finally, an orifice is made at the bottom of the blind hole and extends through the material of the expansion bush into a tool reception space which is delimited in the expansion bush.

A rotatable chuck for clamping a shank portion of a rotatably operating machining tool includes a rotatable chuck body provided with a cylindrical bore concentric with a rotation axis of the chuck body. The circumferential surfaces of a clamping portion of the bore are arranged to apply a clamping force around the circumference of the shank portion of the tool when it is mounted in the chuck to fixate the tool in the chuck. The chuck is provided with auxiliary pull out preventing means for preventing inadvertent pull out of the tool in the axial direction of the bore during machining operation, as well as auxiliary rotary preventing means for preventing inadvertent rotation in at least one direction in relation to the chuck during machining operation. The auxiliary pull out and rotary preventing means include an attachment member positionable in an inner portion of the bore and attachable to the shank portion to be clamped, such that the tool and the attachment member will be prevented from being pulled apart in the axial direction and from being rotated in at least one direction in relation to each other.

An electrically-adjustable tool holder precisely movable in a straight line within a magnetic field under electrical stimulation includes a handle body, a connecting member, and a driving member. The connecting member has a first end securely coupled to an end of the handle body, a second end opposite to the first end, and defines a through hole passing through the first end and the second end. The driving member includes a magnet securely received in the through hole, and an electrical electric coil movably received in the magnet. The electric coil is configured to be securely coupled to the tool, and moves the tool up or down along the central axis of the handle body.

A chuck for a tool comprises a device for supplying a cooling and/or lubricating medium to a medium channel in a tool held in the chuck, an adjusting screw, and securing means. The adjusting screw serves as a stop for the tool held in the chuck, is arranged in the chuck, is adjustable in relation to the chuck in the axial direction of the chuck, and interacts with a pipe element. The pipe element is held rotatably in the chuck and the securing means limit an axial displacement of the pipe element at least in the direction of the adjusting screw. The pipe element and the adjusting screw are connected in a rotationally fixed but axially displaceable manner with respect to each other.

A chuck for a power tool has a central receptacle, arranged in the body of the chuck, having a locating opening for axially inserting a shank-type tool. A reducing sleeve is arranged at least partly in the central receptacle, and a clamping device is provided for at least locally reducing the cross section of the central receptacle. A fixing device is provided which specifies a defined arrangement of the reducing sleeve in relation to the locating opening both with the chuck clamped and with the chuck unclamped.

A tool holder has a body with a spindle side for fastening the tool holder to a spindle of a machine tool and a tool side for accommodating a tool and has a lubricating media passage from the spindle side to the tool side that contains a lubricating media bush adjustable in the axial direction in the body. The lubricating media bush opens out on the tool side of the body, wherein a guide for the lubricating media hush is provided in the body. The guide contains a fitting section in which the lubricating media bush is adjustably guided, wherein a seal is provided which seals the lubricating media bush relative to the body.

A hydraulic expansion chuck includes a basic body, an expansion bush which is received in the basic body and defines a reception space for a tool to be clamped, and a pressure chamber which is delimited between the expansion bush and the basic body. A securing pin is provided, which extends through the basic body and the expansion bush into the reception space. A method for producing a hydraulic expansion chuck is disclosed. First, a basic body is provided with a blind hole, into which an internal thread is cut. Then, an expansion bush is soldered into the basic body. Finally, an orifice is made at the bottom of the blind hole and extends through the material of the expansion bush into a tool reception space which is delimited in the expansion bush.

The invention relates to tool mount with a base body and a receptacle that is joined with the base body for torque transmission and anchored in the base body in an axially movable manner with a spring preload. The base body exhibits a shank section with a recess that is open on the machine tool side, and a bushing section that axially lengthens the shank section, with a guide borehole that is open on the tool side and separated from the recess of the shank section by a radial dividing wall. The receptacle exhibits a guide section that is guided in the guide borehole of the bushing section in an axially movable manner. The receptacle is anchored by means of an anchor that passes through an axial opening in the radial dividing wall and can be actuated for setting the spring preload via the recess of the base body.
