Definitions
- the present invention relates to a tool for machining a workpiece.
- This tool is preferably a rotary tool.
- the tool according to the invention has a tool holder and a cutting plate detachably arranged thereon with the aid of a clamping means.
- the cutting insert is preferably designed as an indexable insert.
- Coolant coolant and lubricant
- An exemplary generic tool which is already known from the prior art, is a tool sold by the applicant under the type designation "clamp holder 356" and "indexable insert 315". The front part of such a tool is shown in detail in fig.
- the tool shown in FIG. 8 is a turning tool which is particularly suitable for grooving.
- the cutting plate is inserted laterally into a cutting plate holder provided in the tool holder and is fastened in this cutting plate holder with the aid of a clamping screw.
- this clamping screw presses the cutting plate with a planar surface provided on its rear side into the base of the cutting plate holder.
- the clamping screw presses the cutting insert on the peripheral side with two contact surfaces running obliquely to one another against corresponding mating contact surfaces of the cutting insert holder.
- the cutting plate is also at least partially covered by the tool holder on the upper side of the cutting insert opposite these contact surfaces, it does not rest against the tool holder on this upper side.
- a coolant outlet opening is arranged in this upper area of the tool holder, which is aligned in such a way that the coolant emerging from it hits the upper side of the cutting plate in the area of the active cutting edge.
- the cutting plate is therefore cooled very close to the active cutting edge.
- the cutting edge of the cutting plate that is used in the respective clamping for machining the workpiece is referred to as the "active" cutting edge.
- the cutting plate has two additional cutting edges, which can also be used to machine the workpiece, but are arranged inside the cutting plate holder in the position shown in FIG. 8 and are “inactive” in this position.
- the cooling in this tool has proven to be quite advantageous. Due to the fact that the top of the cutting plate does not rest against the tool holder, there is a small gap between the cutting plate and the tool holder between the top of the cutting plate and the opposite wall section of the tool holder below the coolant outlet.
- a disadvantage of the embodiment shown in FIG. 9, however, is that the coolant must now be sprayed obliquely in the direction of the active cutting edge, which is problematic, especially in the case of deep punctures or machining on a shoulder, since the coolant then hardly no longer reaches the active cutting edge, since the active cutting edge is covered by the workpiece to be machined.
- a tool according to claim 1 has the following features: a cutting insert with a first side, an opposite second side and a peripheral surface extending between the first side and the second side, with a first cutting insert contact section and a second cutting insert contact section running transversely thereto on the peripheral surface and a third insert abutment section is arranged on the second side, the insert having an effective cutting edge which is arranged on an upper side which forms part of the peripheral surface and faces away from the first and the second insert abutment section ; a tool holder with a cutting insert holder, which is designed as an at least relative depression and is set up to receive the cutting insert in such a way that a first part of the cutting insert is arranged in the depression net and a second part of the cutting tip, on which the effective cutting edge is arranged, is located outside of the cutting tip holder and protrudes at least partially from the tool holder, the cutting tip holder being defined by a depression base and a plurality of walls running
- the three tip abutting portions and the three corresponding holder abutting portions can be aligned orthogonally to each other. However, this does not have to be the case; they can also be oriented obliquely to one another at any desired angle.
- the first and the second cutting-insert contact section are aligned obliquely at an angle of less than 90° to one another and are each aligned orthogonally to the third cutting-insert contact section. The same preferably applies correspondingly to the holder contact sections.
- the cutting plate and holder contact sections can be designed in the form of points or lines or as flat sections.
- peripheral side of the cutting tip running between the first side and the second side is referred to here as the "peripheral surface”.
- this does not mean a planar surface, but a surface composed of many sub-surfaces, which forms the entire circumference of the cutting plate and can be curved, angled or provided with edges as desired.
- peripheral surface the term “peripheral side” could also be used in general.
- more general terms such as “front” and “back” could be used instead of the terms “first side” and "second side” of the insert.
- the gap between the top of the cutting plate and the opposite third wall of the cutting plate holder is designed in such a way that it widens towards the front, ie in the direction from the back to the front of the cutting plate. More specifically, the height of the gap increases in the gap depth direction, which is parallel to the longitudinal axis of the opening, from the rear of the tip toward the front of the tip. The height of the gap is measured as the distance from the top of the cutting plate to the third wall of the cutting plate holder. Due to this widening of the gap between the top of the cutting plate and the third wall of the cutting plate holder, the chips can no longer accumulate so easily in the gap, since they are pushed out of the gap towards the front (i.e. towards the first side of the cutting plate).
- the coolant outlet can remain at the same point as shown in FIG. 8 . This means that cooling very close to the cutting edge is still possible.
- the type of clamping of the cutting insert in the cutting insert holder can also remain as previously described with regard to FIG. 8 .
- the height of the gap increases steadily along the gap depth direction from the rear side of the cutting plate to the front side of the cutting plate. There are therefore no sudden changes in the height of the gap along the gap depth direction, and the further you get along the gap depth direction towards the front of the insert, viewed from the rear of the cutting insert, the larger the height of the gap becomes.
- the increase in the height of the gap along the gap-depth direction need not be continuous.
- the third wall has a first planar surface which extends at an acute angle to a second planar surface arranged on the upper side of the cutting insert. According to this configuration, the gap is therefore delimited by two planar surfaces. The gap thus widens in a funnel shape towards the front, which in turn is advantageous with regard to the chip flow out of the gap.
- the acute angle is between 3° and 60°, preferably between 10° and 45°, particularly preferably between 15° and 30°.
- An angle greater than 15° is particularly preferred, since even if a chip does get caught in the gap, no self-locking occurs.
- the particularly preferred upper limit of 30° for the acute angle is due in particular to the fact that with such an alignment of the two planar surfaces on the third wall of the cutting insert holder and the top of the cutting insert there is still enough space for the internal coolant channel and its Coolant outlet opening remains, so that cooling close to the cutting edge is possible from above the cutting plate.
- the second planar surface provided on the upper side of the cutting insert is parallel to a longitudinal axis of the opening through which the clamping means can be inserted.
- This longitudinal axis of the opening is preferably the axis of symmetry of the opening, which coincides with the longitudinal axis of the clamping means.
- the third wall of the cutting insert receptacle completely covers the section of the upper side of the cutting insert that belongs to the first part of the cutting insert arranged in the depression.
- the coolant outlet opening can thus be aligned centrally in relation to the active cutting edge, despite the gap increasing towards the front.
- the gap is not delimited by two planar surfaces (first and second planar surfaces).
- the third wall is according to this one Configuration designed as a curved surface. Viewed in cross-section, the third wall according to this configuration is designed to be concavely arched. Viewed in cross section, the third wall can be designed as a radius, elliptical or as a free form. The above-mentioned effect of improved chip flow out of the gap also results with such a shape.
- first cutting-insert contact section and the second cutting-insert contact section are aligned at an angle of >60°.
- first holder contact section and the second holder contact section are also aligned at an angle of >60° to one another.
- the cutting plate has essentially the shape of a regular polygon.
- the first and the second insert contact section would be aligned at an angle of 60° to one another.
- the stated angle is 90°, 180° or 120°, respectively.
- the coolant outlet opening is arranged on a component of the tool holder which is formed integrally with the third wall. This component is preferably what is known as the superstructure, which at least partially hangs over the cutting insert.
- an imaginary plane which divides the coolant channel into two halves of equal size, intersects the upper side, the first cutting insert contact section and the second cutting insert contact section when the cutting insert is in the mounted state.
- This imaginary plane is particularly preferably a plane which is aligned orthogonally to the longitudinal axis of the clamping means. Furthermore, it is preferable that this imaginary plane is orthogonal to the first and second tip abutment portions and parallel to the third tip abutment portion.
- the third cutting insert contact section is aligned orthogonally to the first and the second cutting insert contact section.
- the third insert abutment section is preferably aligned orthogonally to a longitudinal axis of the opening provided in the insert.
- the first and second insert abutment sections are preferably aligned parallel to the longitudinal axis of the opening.
- the cutting insert is also preferably rotationally symmetrical to the longitudinal axis of the opening. Any body which, when rotated by a constant angle of less than 360°, is reproduced on itself is referred to as "rotationally symmetrical”.

- Figures 7a and 7b show a perspective view and a cross-sectional view of a third embodiment of the tool according to the invention.
- FIG. 9 shows a perspective view of a detail of another generic tool according to the prior art.
- the tool according to the invention is identified therein in its entirety by the reference number 10 .
- the tool 10 has a tool holder 12 and a cutting insert 14 detachably fastened therein.
- the tool holder 12 has an essentially beam-shaped clamping section 16 and a cutting insert receiving section 18 arranged on the front side of the clamping section.
- the clamping section 16 serves to clamp the tool holder 12 in a machine tool.
- the cutting plate receiving section 18 serves to hold the cutting plate 14.
- a cutting insert receptacle 20 is provided laterally, which is used to hold the cutting insert 14 .
- the cutting insert holder 20 is designed as a depression and is set up to hold the cutting insert 14 in such a way that at least a large part of the cutting insert 14 is arranged in the depression forming the cutting insert holder 20 and the remaining part of the cutting insert, which is used when machining a workpiece with the workpiece comes into contact, is outside of the insert holder 20 (see Fig. 2).
- the cutting plate 14 In the plan view from the side shown in FIG. 2, the cutting plate 14 essentially has the shape of an equilateral triangle. In each of the three corners of this triangle, the cutting plate 14 has a cutting head 22, 22', 22" with a cutting edge 24, 24', 24" for machining a workpiece.
- the three cutting heads 22, 22′, 22′′ are preferably designed identically to one another, so that they can be used in the same way for machining a workpiece.
- the cutting head 22 is used for machining of the workpiece is used, while the other two cutting heads 22', 22'' are not used and are housed in the cutting plate holder 20.
- the cutting edge 24 of the cutting head 22 is therefore referred to as the "active" cutting edge. As soon as this active cutting edge 24 is worn, the cutting insert 14 can be detached from the tool holder 12, rotated through 60° and reattached to the tool holder 12, so that the cutting edge 24' or 24'' then functions as the active cutting edge.
- the cutting insert 14 is fastened to the tool holder 12 with the aid of a clamping device 26 .
- the clamping means 26 is designed as a clamping screw which engages in a corresponding thread 27 provided in the interior of the tool holder 12 (see FIG. 5).
- a clamping bolt could also be used for the screw, which engages in an unthreaded opening in the tool holder 12 .
- the clamping means 26 is introduced into a central opening 30 of the insert.
- This opening 30 is designed as a through-opening which penetrates the first side 28 of the cutting plate 14 as well as the opposite second side 32 of the cutting plate 14 .
- a peripheral surface 34 extends transversely thereto between the first side 28 and the second side 32 of the insert 14. This peripheral surface 34 extends between the first side 28 and the second side 32 around the entire circumference of the insert 14. Equivalent to In the terminology “first side” and “second side”, this peripheral surface 34 can also be referred to as the peripheral side of the cutting tip 14 .
- the clamping means 26 presses the cutting insert 14 in the clamped state both with its second side 32 and with its peripheral side 34 into the cutting insert holder 20.
- the cutting insert 14 has three cutting insert contact sections 36, 38, 40 which are attached to corresponding holders -Abutment sections 42, 44, 46 of the insert holder 20.
- the three cutting insert contact sections 36, 38, 40 run transversely to one another, with the first two cutting insert contact sections 36, 38 being aligned at an angle > 60° to one another and the third cutting insert contact section 40 being orthogonal to the first two cutting insert contact sections 36, 38 runs.
- the first two insert bearing sections 36, 38 are arranged on the peripheral side 34 of the insert 14.
- the third insert abutment section 40 is arranged on the second side 32 of the insert 14 .
- the cutting insert 14 rests with the third cutting insert contact section 40 arranged on the second side 32 against the third holder contact section 46, which is located in the base 48 of the depression forming the cutting insert receptacle 20.
- the cutting insert receptacle 20 has a plurality of walls 50, 52, 54 which the cutting insert 14 on the peripheral side surround.
- the first holder contact section 42 is arranged, which rests against the first cutting plate contact section 36 in the assembled state.
- the second holder contact section 44 is arranged on the second wall 52 and rests against the second cutting plate contact section 38 in the assembled state.
- the third wall 54 is not in contact with the cutting tip 14 .
- a gap 58 is thus formed between the third wall 54 of the cutting insert holder 20 and the upper side 56 of the cutting insert 14 (see FIG. 5). The shape of this gap 58 is explained in detail below.
- the clamping means 26 implemented as a clamping screw presses the cutting insert 14 with its three cutting insert contact sections 36, 38, 40 against the holder contact sections 42, 44, 46 provided on the walls 50, 52, 54 of the cutting insert receptacle 20. That the clamping screw 26 presses the third insert contact section 40 in the mounted state against the third holder contact section 46 is easy to understand.
- the pressure of the clamping screw 26 on the first and the second insert contact section 36, 38 or the first and second holder contact section 42, 44 results from the clamping screw 26 being pulled down. This pull-down is due to the fact that the longitudinal axis of the clamping means 60 in the assembled state of the cutting insert 14 is slightly offset from the longitudinal axis 62 of the opening 30 provided in the cutting insert 14 (see FIGS. 4 and 5). This ensures a mechanically defined and stable insert seat.
- the upper side 56 of the cutting plate 14 is at least partially covered by a superstructure 64 of the tool holder 12.
- This superstructure 64 is part of the insert receiving section 18 of the tool holder 12.
- the superstructure 64 is integrally connected to the clamping section 16 of the tool holder 12.
- Inside this superstructure 64 is an internal coolant passage 66 (see Figure 4).
- the internal coolant channel 66 runs in the interior of the tool holder 12 first through the clamping section 16 and branches off at the end of the clamping section 16 into a transverse bore 68 which leads into the superstructure 64 .
- the internal coolant channel 66 finally opens into a coolant outlet opening 70 which is arranged in the superstructure 64 above the cutting plate 14 .
- the coolant outlet opening 70 is in the mounted state of the cutting insert 14 thus aligned on the top 56 thereof.
- the coolant outlet opening 70 is preferably aligned in such a way that the coolant exiting from it hits the active cutting edge 24 arranged on the upper side 56 .
- the third wall 54 of the insert holder 20 forms the lower part of the superstructure 64 which faces the upper side 56 of the insert 14 .
- this gap 58 (see FIG. 5). Starting from the second side 32 of the cutting tip 14 , this gap 58 widens towards the first side 28 of the cutting tip 14 . More precisely, the height h of the gap 58 increases along a gap depth direction t, starting from the second side 32 towards the first side 28. The height h of the gap 58 is the distance between the top side 56 of the cutting plate 14 and the third wall 54 called the cutting plate holder 20.
- the gap depth direction t designates the dimension of the gap 58, which is measured parallel to the longitudinal axis 60 of the clamping means or the longitudinal axis 62 of the opening (see FIG. 5).
- the third wall 54 has a first planar surface 72 which bounds the gap 58 upwardly.
- gap 58 is bounded by a second planar surface 74 disposed on top surface 56 of insert 14 .
- the two planar surfaces 72, 74 extend at an acute angle a to one another.
- Such a wedge-shaped gap 58 has the advantage that lifted chips that get into the gap 58 can flow out of the gap 58 again very easily without getting caught in it. At the same time, this does not affect the arrangement of the coolant outlet opening 70, so that it can continue to be aligned directly with the active cutting edge 24 in order to ensure cooling that is as close as possible to the cutting edge.
- the size of the angle ⁇ is preferably in the range from 3° to 60°. A range from 10° to 45° is particularly preferred. The range from 15° to 30° is particularly preferred.
- Such opening angles have the advantage that self-locking does not occur even if chips do get caught in the gap 58 .
- the opening angle a should also not be large, since otherwise the coolant outlet opening 70 would have to be offset further upwards, which would have a disadvantageous effect on the cooling of the active cutting edge 24 .
- Fig. 6a and 6b a second embodiment of the tool 10 according to the invention is shown. This embodiment differs from the first embodiment shown in Figs. 1-5 essentially in the way the gap 58 is designed.
- the third wall 54 which forms the underside of the superstructure 64, here has two mutually aligned surfaces 76, 78 which merge along an edge 80 into one another. In other words, the third wall 54 is angled in this embodiment.
- Such an embodiment has the particular advantage that the gap 58 is opened even further towards the outside, but without impairing the coolant outlet opening 70 for this purpose. This can still remain in place.
- the gap 58 which is even further open to the outside, ensures a further improved chip flow.
- the third wall 54 which forms the underside of the superstructure 64, is designed as a curved surface 82 here. Viewed in cross section, this curved surface 82 can be designed as a sector of a circle or part of an ellipse. This curved surface 82, which is preferably designed with a concave curvature in order not to collide with the coolant outlet opening 70, can also be designed as a free-form surface.
- the gap 58 increases continuously along the gap depth direction t from the inside to the outside, ie starting from the rear side 32 of the cutting plate towards the front side 28 of the cutting plate.
- the coolant outlet opening 70 is arranged in such a way that the coolant jet emerging from it hits the active cutting edge 24 as centrally as possible.
- An imaginary plane 84 which divides the coolant outlet opening 70 into two halves of equal size, intersects the upper side 56, the first and the second cutting insert contact section 36, 38 when the cutting insert 14 is in the installed state.
- This imaginary plane 84 preferably intersects that on the upper side 56 arranged planar surface 77, the first insert abutment portion 36 and the second insert abutment portion 38 orthogonal.
- This imaginary plane 84 corresponds to the section plane IV-IV indicated in FIG.
- the imaginary plane 84 is preferably aligned parallel to and disposed between the first and second sides 28, 32 of the insert 14.
- one of the other two cutting heads 24', 24" can also be used as the active cutting head of the cutting plate 14.
- the cutting plate 14 separated from the tool holder 12 by loosening the clamping screw 26, rotated by 60° and fixed again to the tool holder 12. With a clockwise rotation of 60°, the cutting head 24'' would then be used as the active cutting head.
- the first cutting insert contact section 36 forms the upper side 56 or the planar surface 74 arranged thereon and the second cutting insert contact section 38 illustrated in the exemplary embodiments then functions as the first cutting insert contact section 36 .
