Tool holding fixture

A method for making a tool holding fixture (1) with a rotationally symmetrical holding body (3) and a sleeve (11), wherein the holding body (3) has a front clamping region (4) with a receiving opening (5) for accepting a tool shank (6) of a rotationally driven tool (2), and a rear-holding region (7) retained in a work spindle of a machine tool comprising the steps of:

• forming the holding body (3) to include at least the rear-holding region (7);
• forming the sleeve from fiber-reinforced plastic;
• and
• applying the sleeve (11) to the holding body (3) using a wrapping or braiding process, wherein the front-clamping region (4) has a plurality of needle-shaped or pin-shaped elements (31) that penetrate into the sleeve (11) during the wrapping or braiding process.

A method for making a tool holding fixture (1) including a sleeve (11) for rotationally driven tools (2), comprising the steps of:

• providing a rotationally symmetrical holding body (3), wherein the holding body (3) comprises a metal surface, and has:
• (a) a front-clamping region (4) with a receiving opening (5) for a tool shank (6) of the tool (2), and (b) a rear-holding region (7) capable of attachment to a work spindle of a machine tool;
• forming the front clamping region (4) and at least one portion of a central region (9) of the holding body (3), as the sleeve (11);
• roughening the metal surface of the holding body in order to improve cohesion between the sleeve (11) and the holding body (3);
• and
• mounting and shrinking the sleeve (11) onto the front-clamping region (4) of the holding body (3) to produce a positive connection between the holding body (3) and the sleeve (11), wherein the sleeve is made of a fiber-reinforced plastic.

A method for making a tool holding fixture (1) including a sleeve (11) for rotationally driven tools (2), comprising the steps of:

• providing a rotationally symmetrical holding body (3), wherein the holding body (3) comprises a thin-walled insert with a metal surface, and has:
• (a) a front-clamping region (4) with a receiving opening (5) for a tool shank (6) of the tool (2), and (b) a rear-holding region (7) capable of attachment to a work spindle of a machine tool;
• completely enclosing the holding body (3) within the sleeve (11) to thereby form the entire outer contour of the tool holding fixture (1);
• roughening the metal surface of the holding body in order to improve cohesion between the sleeve (11) and the holding body (3);
• and
• mounting and shrinking the sleeve (11) onto the front-clamping region (4) of the holding body (3) to produce a positive connection between the holding body (3) and the sleeve (11), wherein the sleeve is made of a fiber-reinforced plastic.

• (a) a front-clamping region (4) with a receiving opening (5) for a tool shank (6) of the tool (2), and (b) a rear-holding region (7) capable of attachment to a work spindle of a machine tool;
• forming one or more cavities in an interior of the sleeve (11) as a layer by a sintering process, wherein the interior sleeve cavities extend longitudinally to an axis of rotation of the tool holding fixture, between two regions of the sleeve (11) made of fiber-reinforced plastic;
• roughening the metal surface of the holding body in order to improve cohesion between the sleeve (11) and the holding body (3);
• and
• mounting and shrinking the sleeve (11) onto the front-clamping region (4) of the holding body (3) to produce a positive connection between the holding body (3) and the sleeve (11), wherein the sleeve is made of a fiber-reinforced plastic.
