Alternatively, the tool interface (and, thereby, the tool supporter) may be integrally formed with a tool in one piece.
The tool (e.g. the separate tool) supported/to be
supported by the tool supporter may, e.g., be a machining tool, such as a drill or a reamer.
The circumferential groove may have a depth which is at least 20% of the radius of the tool supporter body at the axial level (seen along the tool-supporter-rotation-axis) of the circumferential groove, wherein, the depth of the

Detailed Description of the Invention
According to figures 1 to 10, a tool supporter 10 for supporting a tool has a tool supporter body 20 which defines a longitudinal tool-supporter-rotation-axis 30 and which
comprises: a machine interface 40, which is configured to be connected to a rotary driving machine in a torque-transmitting manner, a tool interface 50, which is fixed to the machine interface 40 and which is configured to support a tool, and an adjusting system (e.g. adjusting mechanism) 60, which is arranged, along the tool-supporter-rotation-axis 30, between the machine interface 40 and the tool interface 50. The adjusting system 60 comprises: an outer circumferential groove 70 which is formed in the tool supporter body 20 and which
extends all around the tool-supporter-rotation-axis 30, wherein the outer circumferential groove 70 comprises two lateral groove walls 75 and 76 opposite to each other, a plurality of screw holes 80, which are arranged along the circumferential groove 70 in a manner to be circumferentially and equally spaced apart from each other and which each extend in a radial direction with respect to the tool-supporter- rotation-axis 30, and a plurality of adjustment screws 90, which are to be inserted into the screw holes 80.
Each screw hole 80 comprises a radial inner threaded portion 100 and a radial outer sliding portion 110. Each adjustment screw 90 comprises a leading threaded portion 120 configured to engage the radial inner threaded portion 100 of the corresponding screw hole 80, and a trailing screw head 130 configured to slidably engage the radial outer sliding portion 110 of the corresponding screw hole 80 to form a respective slide engagement 135.
The respective slide engagement 135 comprises a radially tapering structure 140 such that by screwing the respective adjustment screw 90 into the corresponding screw hole 80 the respective trailing screw head 130 applies a lateral spreading force 145 to the lateral groove walls 75 and 76 via the radially tapering structure 140 of the respective slide engagement 135 to cause a local (that is, in the location area of the respective adjustment screw 90) and lateral spreading of the groove 70, by which the tool interface 50 is
correspondingly tilted relative to the machine interface 40 around a corresponding tilt axis 147 (one tilt axis 147 is exemplarily shown in Fig. 8) transverse to the tool-supporter- rotation-axis 30.
The tool supporter 10 of the embodiment of Figs. 1 to 10 is formed as a tool holder 150, wherein the tool interface 50
is configured to fixedly attach a separate tool (e.g. a machining tool, such as a drill or a reamer) (not shown) to the tool holder 150 in a releasable manner. The tool holder 150 may be formed as shrink-fit tool holder, wherein the tool interface 50 is configured to fixedly attach the separate tool (not shown) to the shrink-fit tool holder via thermal
shrinking in a releasable manner.
As shown in Figs. 1 and 6, the circumferential groove 70 has a depth D which is about 30% of the radius R of the tool supporter body 20 at the axial level (seen along the tool- supporter-rotation-axis 30) of the circumferential groove 70.
As shown in Fig. 6, the circumferential groove 70 has a depth D which is about 160% of a core hole diameter CD (e.g. a core hole diameter CD according to DIN ISO 1502:1996-12) corresponding to a thread size provided in the plurality of screw holes 80 by the respective radial inner threaded portion 110.
The radially tapering structure 140 comprises the radial outer sliding portion 100 of a respective screw hole 80 having a conical shape so as to taper, with a corresponding tool- supporter-body-sided inclination 160, in a radially inward direction relative to the tool-supporter-rotation-axis 30. The radially tapering structure 140 further comprises the trailing screw head 130 of a respective adjustment screw 90 having a conical shape so as to taper, with a corresponding screw-head sided inclination 170, in the direction from its trailing screw head 130 toward its leading threaded portion 120. The corresponding tool-supporter-body-sided inclination 160 corresponds to the corresponding screw-head-sided inclination 170. In other words, the conical shape of the radial outer sliding portion 100 of the respective screw hole 80 matches
the conical shape of the trailing screw head 130 of the respective adjustment screw 90.
The plurality of screw holes 80 comprises four screw holes 70, and the plurality of adjustment screws 90 comprises four adjustment screws 90.
The tool supporter 10 further comprises a cover ring (e.g. a lock cap) 180 adapted to be attachable to the tool supporter 10 so as to cover the screw holes 80 and the adjustment screws 90 inserted into the screw holes 80. The cover ring 180
comprises an inner thread 185 on an inner circumferential surface 190 thereof, and the tool supporter body 20 comprises, on an outer surface thereof, at the axial level (seen along the tool-supporter-rotation-axis 30) of the adjusting system 60, an outer thread 195, whereby the cover ring 180 can be screwed onto the tool supporter body 20. The cover ring 180 is adapted in a manner so as to be attachable/detachable to the tool supporter 10/tool supporter body 20 only with a unique tool (not shown) which, e.g., does not match a tool norm.
E.g., in Fig. 1, the cover ring 180 is not attached to the tool supporter 10/tool supporter body 20, and, e.g., in
Fig. 2, the cover ring 180 is attached to the tool supporter 10/tool supporter body 20 and, thereby, covers the screw holes 80 and the adjustment screws 90 inserted into the screw holes 80.
As shown in Fig. 8, tightening one of the adjustment screws 90 results in its trailing screw head 130 to apply a spreading force 145 via both lateral groove walls 75 and 76 to both, the machine interface 40 and the tool interface 50.
Thereby, a tilting 200 of the tool interface 50 relative to the machine interface 40 in the direction of the tightening of the respective adjustment screw 90 is caused. As shown in
Fig. 9, tightening the opposite adjustment screw 90 results in a tilting in the opposite direction 200.
In the following, a tool supporter 10 according to another embodiment is described based on Fig. 11. The embodiment of Fig. 11 generally comprises the features of the embodiments of Figs. 1-10, so that, in the following merely the differences between these embodiments are described.
