PREAMBLE TO THE DESCRIPTION The following specification particularly describes the invention and the manner in which it is to be performed : - ENGLISH TRANSLATION VARIFICATION CERTIFICATE u/r. 20(3)(b) I, Mr. HIRAL CHANDRAKANT JOSHL an authorized agent for the applicant, LEGUIN HERMANN do hereby verify that the content of English translated complete specification filed in pursuance of PCT International application No. PCT/EP2006/008072 thereof is correct and complete. The invention concerns a device for the processing of work pieces with a tool, which is connected to a holder via a tensioning device, whereby a deformable sleeve is assigned to the holder. State-of-the-Art Such devices are known in many forms and executions and are available in the market. They primarily serve the purpose of processing of work pieces within processing stations, like, e.g. turning lathes, milling machines, or similar. From DE 198 00 424 Al, we are familiar with a device of the above mentioned kind, wherein the tool is inserted in a borehole in the holder with a shaft and is held together by means of a tensioning device. The tool ends with a front face in the borehole, which is beveled and coacts with a transverse arrester. The transverse arrester extends radially across the borehole in the holder, whereby the tool is introduced in this borehole and is fixed in its axial and radial position by means of the tensioning device acting in axial direction. What has proved to be disadvantageous in this device is the fact that the retention of this tool in its radial position is often not sufficient. From DE 22 52 275 Al, we are familiar with a device for the holding of boring spirals in a boring socket. Thereby, a coupling sleeve unit is disposed between the boring spiral and the boring socket, wherein a saw notch has been inserted at right angle to the longitudinal axis. In doing so, the coupling sleeve unit is divided into a propulsive section and a gripping section. Both sleeve sections can no longer be joined without a gap through tightening of a coupling nut, because the coupling sleeve parts abutting the boring spiral in a form fit can no longer be screwed together in the spiral groove direction of the boring spiral, owing to their rotation preventing axial groove channel. Thus, when the coupling nut is tightened, the lower coupling sleeve part presses down on the ground backfaces of the boring spiral and clamps them tightly into the boring socket. In DE 869 892 C, a tensioning device is described, which acts according to the vacuum flask principle. Through a coupling nut, an elastic element disposed between the clamping mandrel and the work piece, is axially deformed in such a way that it spreads out radially, which results in a wedging effect. Task The task of the invention at hand is to improve the radial fixing of the work piece in a holder. Solution of the Problem The solution of the task is achieved by the fact that the sleeve is non-circular and retains the work piece or engages in a recess in the tool, whereby a turning element with an internal and/or external contour similar to a non-circular external and/or internal contour of the sleeve is attached on top of the sleeve or inserted inside the sleeve and turned, whereby the sleeve is deformed in such a way by the turning of the turning element that the tool is fixed in radial direction. The advantage of this non-circular, deformable sleeve is that it can be deformed in such a way by the appropriate turning element that it tightly clamps the retained tool, so that a radial movement of the tool becomes impossible. The same is naturally valid even when the sleeve does not retain the tool but sits in a recess in the tool. Even here, the sleeve has a wedging effect through the deformation in the recess of the tool. The sleeve is preferably made of metal, whereby, self-evidently, the wall strength of the sleeve is not too thick, thus, allowing for a deformation. Furthermore, the sleeve can be directly fused to the holder, i.e. it can be manufactured in one piece with the holder or is manufactured separately and is later connected to the holder through appropriate connecting measures. In a preferred execution example, the sleeve is designed cross-sectionally and polygonally, whereby the term polygonal appears exaggerated. For instance, the sleeve can be designed in triangular shape, whereby the corner areas are, however, extremely rounded-off, so that the angular shape is hardly visible with the naked eye. In the execution specimen, wherein the work piece extends across the sleeve, a turning element is attached on top of the sleeve, which demonstrates a retention with an internal contour, which approximately corresponds to the external contour of the sleeve. This implies that the turning element can, principally, be attached onto the sleeve only in certain rotating positions. If the turning element is then rotated, its "corner ranges" of the internal contour drive against the "corner ranges" of the external contour, whereby other areas of the sleeve are deformed in such a way that they are pressed against the work piece. In the other execution example, the sleeve sits in a recess in the work piece. The tool, in this case, could be, for instance, a milling cutter or a saw blade. Hereby, the recess in the tool itself is round-shaped. Now, if a turning element with an external contour similar to the non-circular internal contour of the sleeve is inserted in the sleeve and turned, there is, one again, a deformation of the sleeve, whereby sleeve areas are pressed against the recess of the tool. Through this execution in accordance with the invention, there is a very favourable tensioning of the device, so that a radial deflection is avoided. Now, if the free end of the tool in the execution example mentioned first is additionally beveled and hits against a cross-bar in the axial boring of a holder, as described in DE 198 00 424 Al, then there is both an axial as well as an extremely secure radial fixing of the tool, with simultaneous prevention of any turning movement of the tool vis-a-vis the holder. Such a fixation works with a high degree of repeated accuracy. Description of the Images Further advantages, characteristics and details of the invention can be derived from the following description of preferred execution examples as well as by means of the drawing. This shows in Figure 1, a partly fragmented representation of a lateral view of a device in accordance with the present invention for the processing of work pieces; Figure 2, a cross-section through the invention, in accordance with Figure 1 along the line II-II; and Figure 3, a cross-section through another execution example of the invention. A device in accordance with the present invention for the processing of work pieces, which have not been shown in detail, is demonstrated by a holder 1, which possesses an axial borehole 2, which has been indicated through dashes. In this borehole 2, a tool 3 is inserted, whereby one end of this tool 3 in the axial borehole 2 is provided with a bevel 4. This bevel 4 coacts with an anti-twist protection, here, a transverse arrester 5, as it has been described in detail in DE198 00 424 Al. Before the tool 3 enters the axial borehole 2, it passes through a sleeve 6, which is encompassed by a turning element 7. The turning element 7 has been executed in the form of a hexagonal nut, in accordance with Figure 2. Essential to the invention and indicated in Figure 2, is the fact that the sleeve 6 demonstrates a jacket 8, which is non-circular in shape. In this example, it abuts the cylinder-shaped tool at three places, 9.1, 9.2 and 9.3, whereas its inside surface 10 maintains an increasing and/or decreasing distance on a very low scale (for instance 3/100) from tool 3 . The turning element 7 forms a retention 11 for the sleeve 6, whereby an internal contour of this retention 11 copies the shape of the non-circular external contour of the sleeve 6. The functioning of the present invention is as follows: The tool 3 is inserted in the sleeve 6, whereby the tool 3, being cylindrical in shape, can rotate freely in the sleeve 6. It abuts the internal contour of the sleeve 6 merely at places 9.1 to 9.3. In this way, it is possible that after the insertion of the tool 3, the same can also be rotated in the axial borehole 2, so that the bevel 4 can be brought into position with the transverse arrester 5. Now, the turning element 7 is attached on top of the sleeve 6, which can only occur in three positions, since the internal contour of the retention 11 of the turning element 7 copies the shape of the external contour of the sleeve 6, which is non-cicular. Now the turning element 7 is rotated with an appropriate key, whereby the rounded-off corner ranges of the internal contour of the retention 11 of the turning element 7 drive against the highly rounded-off corner ranges of the jacket of the sleeve 6 and have a wedging effect on the sleeve 6, which has the effect, that the sleeve 6 is pressed tightly against the tool 3 at minimum 3 places 9.1 to 9.3, so that a radial movement of the tool 3 becomes impossible. Since the coacting wedging surfaces of the turning element 7 and the sleeve 6 demonstrate an very minor acclivity against each other, there is a self-inhibiting effect between turning element 7 and sleeve 6, which can only be overcome by a tool, which is displaced in opposite direction by the turning element 7. Figure 3 attempts to indicate a reverse arrangement of a tool holder. Even here, the holder 1 is provided with an attached sleeve 6. This sleeve 6 is, like in the other execution example, likewise non-circular, for instance, by way of exaggeration, triangular and/or polygonal. A tool 3.1 is, however, not inserted in the sleeve 6 here, but possesses a recess 12, which are circular. Since the outside contour of the sleeve 6 is likewise non-cicular, it likewise abuts the internal contour of the recess 12 at three places, 9.4, 9.5 and 9.6. Now, a turning element 7.1 is inserted in the sleeve 6 for tensioning, whereby this turning element 7.1 is likewise non-circular in shape. Preferably, it demonstrates an external contour 13, which corresponds to the internal contour of the sleeve 6. On rotation of the turning element 7.1, there is, in turn, a deformation of the sleeve 6, which has the effect that specific places on the external contour of the sleeve 6 press against the internal contour of the recess 12, and the tool 3.1 is, thus, wedged on the sleeve 6.

I, Mr. HIRAL CHANDRAKANT JOSHL an authorized agent for the applicant, LEGUIN HERMANN do hereby verify that the content of English translated complete specification filed in pursuance of PCT International application No. PCT/EP2006/008072 thereof is correct and complete.

The invention concerns a device for the processing of work pieces with a tool, which is connected to a holder via a tensioning device, whereby a deformable sleeve is assigned to the holder.
State-of-the-Art
Such devices are known in many forms and executions and are available in the market. They primarily serve the purpose of processing of work pieces within processing stations, like, e.g. turning lathes, milling machines, or similar.
From DE 198 00 424 Al, we are familiar with a device of the above mentioned kind, wherein the tool is inserted in a borehole in the holder with a shaft and is held together by means of a tensioning device. The tool ends with a front face in the borehole, which is beveled and coacts with a transverse arrester. The transverse arrester extends radially across the borehole in the holder, whereby the tool is introduced in this borehole and is fixed in its axial and radial position by means of the tensioning device acting in axial direction.
What has proved to be disadvantageous in this device is the fact that the retention of this tool in its radial position is often not sufficient.
From DE 22 52 275 Al, we are familiar with a device for the holding of boring spirals in a boring socket. Thereby, a coupling sleeve unit is disposed between the boring spiral and the boring socket, wherein a saw notch has been inserted at right angle to the longitudinal axis. In doing so, the coupling sleeve unit is divided into a propulsive section and a gripping section. Both sleeve sections can no longer be joined without a gap through tightening of a coupling nut, because the coupling sleeve parts abutting the boring spiral in a form fit can no longer be screwed together in the spiral groove direction of the boring spiral, owing to their rotation preventing axial groove channel. Thus, when the coupling nut is tightened, the lower coupling sleeve part presses down on the ground backfaces of the boring spiral and clamps them tightly into the boring socket.

In DE 869 892 C, a tensioning device is described, which acts according to the vacuum flask principle. Through a coupling nut, an elastic element disposed between the clamping mandrel and the work piece, is axially deformed in such a way that it spreads out radially, which results in a wedging effect.
Task
The task of the invention at hand is to improve the radial fixing of the work piece in a holder.
Solution of the Problem
The solution of the task is achieved by the fact that the sleeve is non-circular and retains the work piece or engages in a recess in the tool, whereby a turning element with an internal and/or external contour similar to a non-circular external and/or internal contour of the sleeve is attached on top of the sleeve or inserted inside the sleeve and turned, whereby the sleeve is deformed in such a way by the turning of the turning element that the tool is fixed in radial direction.
The advantage of this non-circular, deformable sleeve is that it can be deformed in such a way by the appropriate turning element that it tightly clamps the retained tool, so that a radial movement of the tool becomes impossible. The same is naturally valid even when the sleeve does not retain the tool but sits in a recess in the tool. Even here, the sleeve has a wedging effect through the deformation in the recess of the tool.
The sleeve is preferably made of metal, whereby, self-evidently, the wall strength of the sleeve is not too thick, thus, allowing for a deformation. Furthermore, the sleeve can be directly fused to the holder, i.e. it can be manufactured in one piece with the holder or is manufactured separately and is later connected to the holder through appropriate connecting measures.

In a preferred execution example, the sleeve is designed cross-sectionally and polygonally, whereby the term polygonal appears exaggerated. For instance, the sleeve can be designed in triangular shape, whereby the corner areas are, however, extremely rounded-off, so that the angular shape is hardly visible with the naked eye. In the execution specimen, wherein the work piece extends across the sleeve, a turning element is attached on top of the sleeve, which demonstrates a retention with an internal contour, which approximately corresponds to the external contour of the sleeve. This implies that the turning element can, principally, be attached onto the sleeve only in certain rotating positions. If the turning element is then rotated, its "corner ranges" of the internal contour drive against the "corner ranges" of the external contour, whereby other areas of the sleeve are deformed in such a way that they are pressed against the work piece.
In the other execution example, the sleeve sits in a recess in the work piece. The tool, in this case, could be, for instance, a milling cutter or a saw blade. Hereby, the recess in the tool itself is round-shaped. Now, if a turning element with an external contour similar to the non-circular internal contour of the sleeve is inserted in the sleeve and turned, there is, one again, a deformation of the sleeve, whereby sleeve areas are pressed against the recess of the tool.
Through this execution in accordance with the invention, there is a very favourable tensioning of the device, so that a radial deflection is avoided. Now, if the free end of the tool in the execution example mentioned first is additionally beveled and hits against a cross-bar in the axial boring of a holder, as described in DE 198 00 424 Al, then there is both an axial as well as an extremely secure radial fixing of the tool, with simultaneous prevention of any turning movement of the tool vis-a-vis the holder. Such a fixation works with a high degree of repeated accuracy.

Description of the Images
Further advantages, characteristics and details of the invention can be derived from the following description of preferred execution examples as well as by means of the drawing. This shows in
Figure 1, a partly fragmented representation of a lateral view of a device in accordance with the present invention for the processing of work pieces;
Figure 2, a cross-section through the invention, in accordance with Figure 1 along the line II-II; and
Figure 3, a cross-section through another execution example of the invention.
A device in accordance with the present invention for the processing of work pieces, which have not been shown in detail, is demonstrated by a holder 1, which possesses an axial borehole 2, which has been indicated through dashes. In this borehole 2, a tool 3 is inserted, whereby one end of this tool 3 in the axial borehole 2 is provided with a bevel 4. This bevel 4 coacts with an anti-twist protection, here, a transverse arrester 5, as it has been described in detail in DE198 00 424 Al.
Before the tool 3 enters the axial borehole 2, it passes through a sleeve 6, which is encompassed by a turning element 7. The turning element 7 has been executed in the form of a hexagonal nut, in accordance with Figure 2.
Essential to the invention and indicated in Figure 2, is the fact that the sleeve 6 demonstrates a jacket 8, which is non-circular in shape. In this example, it abuts the cylinder-shaped tool at three places, 9.1, 9.2 and 9.3, whereas its inside surface 10 maintains an increasing and/or decreasing distance on a very low scale (for instance 3/100) from tool 3 .

The turning element 7 forms a retention 11 for the sleeve 6, whereby an internal contour of this retention 11 copies the shape of the non-circular external contour of the sleeve 6.
The functioning of the present invention is as follows:
The tool 3 is inserted in the sleeve 6, whereby the tool 3, being cylindrical in shape, can rotate freely in the sleeve 6. It abuts the internal contour of the sleeve 6 merely at places 9.1 to 9.3. In this way, it is possible that after the insertion of the tool 3, the same can also be rotated in the axial borehole 2, so that the bevel 4 can be brought into position with the transverse arrester 5.
Now, the turning element 7 is attached on top of the sleeve 6, which can only occur in three positions, since the internal contour of the retention 11 of the turning element 7 copies the shape of the external contour of the sleeve 6, which is non-cicular.
Now the turning element 7 is rotated with an appropriate key, whereby the rounded-off corner ranges of the internal contour of the retention 11 of the turning element 7 drive against the highly rounded-off corner ranges of the jacket of the sleeve 6 and have a wedging effect on the sleeve 6, which has the effect, that the sleeve 6 is pressed tightly against the tool 3 at minimum 3 places 9.1 to 9.3, so that a radial movement of the tool 3 becomes impossible. Since the coacting wedging surfaces of the turning element 7 and the sleeve 6 demonstrate an very minor acclivity against each other, there is a self-inhibiting effect between turning element 7 and sleeve 6, which can only be overcome by a tool, which is displaced in opposite direction by the turning element 7.
Figure 3 attempts to indicate a reverse arrangement of a tool holder. Even here, the holder 1 is provided with an attached sleeve 6. This sleeve 6 is, like in the other execution example, likewise non-circular, for instance, by way of exaggeration,

triangular and/or polygonal. A tool 3.1 is, however, not inserted in the sleeve 6 here, but possesses a recess 12, which are circular. Since the outside contour of the sleeve 6 is likewise non-cicular, it likewise abuts the internal contour of the recess 12 at three places, 9.4, 9.5 and 9.6.
Now, a turning element 7.1 is inserted in the sleeve 6 for tensioning, whereby this turning element 7.1 is likewise non-circular in shape. Preferably, it demonstrates an external contour 13, which corresponds to the internal contour of the sleeve 6. On rotation of the turning element 7.1, there is, in turn, a deformation of the sleeve 6, which has the effect that specific places on the external contour of the sleeve 6 press against the internal contour of the recess 12, and the tool 3.1 is, thus, wedged on the sleeve 6.
