Description

Turret tool carrier, tool, turning-milling machine, chuck and use of an adapter

[Ol] The invention relates to a turret tool carrier, a tool with a turret tool carrier, a turning-milling machine with such a turret tool carrier and the use of an adapter for fastening a processing body to a turret tool carrier.

[02] In many areas of the manufacturing industry or mechanical engineering, the task of machining a workpiece in the form of turning, milling, grinding, rolling, drilling and / or similar steps is a regular task. These processing steps can be carried out on combined turn-mill machines without having to remove the workpiece between the individual processing steps.

[03] In the classical form simple lathes are known, which can accommodate the workpiece on a main spindle. For this purpose, a feed is usually provided. Often these machines still have a counter spindle, which is arranged coaxially with the main spindle at the other end of the machine, so that there is a processing space for workpieces between the main spindle and the counter spindle. A workpiece can either be inserted in the main spindle or in the counterspindle if it is to be machined. It is also possible to use in each case a workpiece for machining in the main spindle and in the counterspindle, which usually reduces the changeover time of the machine and thus allows them to work more economically, but this also requires that between the workpieces a sufficiently large space for about needed tools remains.

[04] The tools themselves are arranged on tool holders of the processing machine, whereby it has prevailed in view of the many types of processing steps to be carried out to form tools in several parts. A multi-part tool consists in particular of a body which serves as a tool carrier. On the one hand, the tool carrier has a connection area for a connection to the machine, often a clamping shaft, for example. On the other hand, the tool carrier on a work area, in which the actual processing body or a plurality of actual processing bodies is or are arranged.

[05] DE-OS 1 477 695 shows a multiple tool holder for turning tools, in particular for thread cutting, wherein it is proposed that a tool carrier is connected on the machine side to a fastening part, while in a work area as the main tool a replaceable thin quill for centering with a corresponding drill has, while directly next to an additional support for a turning steel is provided. This should be used for planning.

[06] EP 1,027,955 Bl proposes a machine tool in which a pivotable ^'tool spindle carriers can be pivoted so that it creates a free space evasive other tools in the processing region between the Einspannfüttern and the tool. For this purpose, it is proposed at the end of the document to clamp a spindle housing on the machine side, so that it is directed to a working area to the tool, where there is provided a milling tool as a main machining body. At the same time, a pivotable spindle carrier is arranged shortly before the working area, which creates a parallel offset further working area in which an additional cutting tool is arranged.

[07] Further multi-part tools with tool carriers are known from EP 0 472 917 A1, DE 1 946 467 A1 or DE 78 35 341 U1.

[08] Tool carriers for a plurality of processing bodies are often manufactured as turret tool carriers. In the case of turret tool carriers, several processing bodies are located in the working area such that they can be used to machine the workpiece without further intermediate steps when the working area is set accordingly to the workpiece. Turret tool carriers therefore often have a turret, which can be rotated about a switching axis and thus can be switched from machining body to machining body.

^■ [09] Thus, such turret tool carriers are often arranged on the tool carriage, which are arranged in movable along the processing space, and in this at the bottom of the machine. The turret can then be that processing body switched into its processing station, which is just needed for the next processing step. Rotary steels, milling heads, grinding heads and drills are often also arranged together on such a turret tool carrier.

[0002] Regardless of whether a conventional tool slide is already to be found on the machine, modern turning-milling machines often have a combined turning-milling spindle which can be moved and set up relatively freely in the processing space. Not infrequently, such a turning-milling spindle can be moved very fine in six degrees of freedom and be employed on the workpiece. Subsequently, the machining can then take place either with a rotating tool on the freely adjustable turning-milling spindle and simultaneously standing main spindle or vice versa. [11] Thus, for example, in a first processing step, the turning-milling spindle can apply a cutting steel to a rotating workpiece; for a second processing step, a lower revolver slide would apply a drill for an axial bore to the then rotating workpiece; meanwhile, the turning-milling spindle may have been moved to the tool store of the machine and have exchanged the cutting steel for a tap, so that after completion of the axial drilling the lower turret with the tool slide is moved away from the workpiece and the turning-milling spindle for Tapping can be applied. Of course, the machine can do without the lower tool carriage, since the turning-milling spindle can equip for the second processing step with a drill from the tool storage of the machine. A tool change on the turning-milling spindle takes place very quickly and is usually completed within 15 seconds.

[12] In order to be able to load several turning steels simultaneously on the turning-milling spindle, turret tool carriers are available, which can be connected to the turning-milling spindle. Thus, from a first cutting iron can be quickly converted to a second cutting iron and on other dies as soon as a shearing iron is worn. When processing, for example, stainless steel occurs a significant wear on turning steels.

The invention is based on the object to make metal processing tasks of the kind described more efficient.

According to a first aspect of the invention, this object solves a turret tool carrier with a connection area and a work area, wherein the connection area is adapted for connection to a combined turn-mill spindle and wherein the work area is adapted for receiving processing bodies, wherein a recording in the work area has a drill chuck.

According to this aspect of the invention, therefore, a chuck is provided on a revolver, which in turn is connected to a combined turning-milling spindle. This results in the great advantage that even when changing the machining body of two different tool categories on the turning-milling spindle, it is not necessary to move the turning-milling spindle to the tool storage of the machine. Numerous machining operations can be carried out considerably more efficiently in this way, and the machine's set-up times are significantly reduced.

[16] In the at least one drill chuck, circumferentially effective machining bodies can be used to operate the machine without further ado, in particular drills or milling heads. When using a turret tool carrier on a turning-milling spindle, it is usually inclined Anstellwinkeln between the axis of rotation of the turning-milling spindle and the axis of the male on the turret processing body, in the case of a chuck so for example a drill. However, this can also be employed by the turning-milling spindle axially without rotation to a rotating workpiece, so that at least one axial bore is always readily possible.

[17] A turret tool carrier is understood above all to mean a one-part or multi-part component which has no degree of freedom in itself. Thus, a turret tool carrier is usually a two-part element, consisting of a clamping shaft and a turret screwed thereto. These two parts are connected without play, while the switching is effected about the indexing axis between the individual blades or drills on the machine. The machine thus rotates the entire turret tool carrier for shifting about its axis.

Preferably, the chuck is in a regular arrangement with other shots on the turret tool carrier. Thus, for example, the turret tool carrier have a regular switching angle, often 30 °, 45 °, 60 ° or 90 ° switching angle can be found. When switching the turret tool carrier would then at least in a switching position on a chuck.

[19] According to a second aspect of the invention, the object solves a turret tool carrier with a connection area and with a working area, wherein the connection area is set up for connection to a combined turn-mill spindle and wherein the work area is set up for receiving processing bodies, which then protrude along receiving axes of the turret tool carrier, wherein a Aufhahmeachse has an oblique angle of attack with respect to a switching axis of the re- volver tool carrier.

[20] It has already been explained that a turret tool carrier is provided so that it can rotate about a switching angle about a switching axis and in this way can set different processing bodies to a workpiece, be it another type of processing body simply an identical machining body as an exchange for a worn first machining body. For this purpose, on the turret tool carrier itself a possibility of rotation of the receptacles of the working area with respect to the connection area can be provided. Often a shift for cost reasons, however, designed so that is connected to the machine tool, the connection for the turret tool carrier, so that simply the connection is rotated by a predetermined switching angle and thus the entire turret tool carrier is rotated by the switching angle. This moves the previously located in the working position on the workpiece machining body from the working position and leads a new machining body in the machining position to the workpiece. In a turn-mill spindle, which engages in the processing space, so easy this spindle, the milling operations rotated about its axis and so a corresponding tool for milling or drilling can be rotated to rotate the switching angle.

[21] In conventional turret tool carriers, the machining bodies are arranged either parallel to the indexing axis or perpendicular to the indexing axis. It can also happen that results in a small angle of mostly 2 ° or 3 ° with respect to the parallel position or the normal position. However, such positions can still be considered essentially parallel or normal to the switching axis.

[22] The invention proposes according to the now presented aspect, in contrast, that the receptacle is formed so that its axis is significantly oblique, so that when inserted processing body and this is also significantly oblique.

Especially when far projecting processing body such as drills are to be used, the tool achieved at obliquely arranged processing bodies a much smaller overall size, so that a total of less processing space must be available to the turning-milling spindle with the tool safely and to be able to move freely. This is especially true when compared to a comparable tool where the drills on the revolver would be perpendicular to the indexing axis. Compared to a revolver with parallel or at least substantially parallel drills arranged there is a much greater freedom to be able to intervene deeply in more complex workpieces without the other drills would be too close to the drill bit currently in use.

[24] Another advantage can be that the turning-milling spindle does not have to be moved as far into the machining area as with conventional turrets. In a drill assembly parallel to the indexing axis, it is necessary that the entire arm of the turning-milling spindle is moved into the processing space and then the turret subsequent head of the spindle arm is pivoted with its axis so that the spindle axis, thus the switching axis of the Revolver and thus the drill are coaxial with the main spindle axis. In an arrangement of the machining body perpendicular to the indexing axis and thus perpendicular to the spindle axis of the spindle head must also be moved very far into the processing room into it. In contrast, the invention makes it possible to position the spindle head relatively far away from the main spindle axis. The spindle head then only has to be inclined so that, together with the inclined position of the machining body, it causes the machining body to lie coaxially with the main spindle axis.

On the one hand, it is possible with such a tool geometry to manage with relatively small processing spaces and thus also relatively small machine tools. On the other hand Even at the same time, two workpieces can be clamped in the processing area, namely on the main spindle and on the counterspindle, even for machining operations that were previously carried out on conventional machines on a clamped workpiece under very scarce sufficient space conditions. The space between them will usually be sufficient to perform axial drilling with a turret or other work with inclined working bodies.

Preferably, the oblique angle of attack of at least one receptacle, preferably several receptacles, particularly preferably all receptacles - sometimes with the exception of a central Axialaufhahme - about 20 ° to 70 °. Here, the angle of attack is measured as the plane angle between the receiving axis of the respective receptacle and the switching axis of the turret tool carrier in a projection of the Aufhahmeachse on that plane in which the indexing axis of the turret tool carrier is located and which is parallel to Aufhahmeachse. If the receiving axis of the receptacle intersects the switching axis, the angle results directly between the two axes. According to this definition, receiving axes of receptacles which receive a machining body parallel to the indexing axis have an angle of attack of 0 °. Aufhahmeachsen, which machining elements can project perpendicular to the indexing axis of the turret tool carrier, have an angle of 90 °. Angles of more than 90 ° between the indexing axis and the Aufhahmeachse do not occur, since they are then referred to in the context of this application with the Komplementwinkel to 180 °. Thus, an angle of attack of 135 ° would be regarded as an angle of attack of 45 °, even if there is another receptacle directed in the other direction with respect to the normal to the switching axis.

In the case of a chuck, the receiving axis results readily as the central axis through the chuck to which the jaws of the chuck taper when tightened. For a screw-on surface, for example, for dies, the Aufhahmeachse results as normal on the Anschraubfläche.

[28] Whereas the described space-saving advantage can already be achieved with a tilted machining body on the tool or a tilted machining body mount on the turret tool carrier, it is preferred that further receiving axes with an oblique angle of attack are arranged at regular intervals on the turret tool carrier with the first receiving axis are. With several regularly spaced recordings, a uniform or at least between several recordings common switching angle can be used, so it is particularly easy to switch the revolver. In this case, particularly little computational effort when switching between two processing bodies on the turret tool carrier is due. In a preferred embodiment, at least two Aufhahmeachsen with an oblique angle in an imaginary conical surface. Such a geometry results exactly when, for one, the two Aufhahmeachsen lie in the same angle to the switching axis and, for another, these two recordings are at the same axial height with respect to the switching axis.

[3O] In a simple case, for example, a turret may be hemispherical shaped, and two or more receptacles are each normal to the surface of the hemisphere. If here two shots have the same angle, they are forcibly at the same axial height to the indexing axis of the turret, and incidentally on a circular path which is perpendicular to the indexing axis of the revolver.

[31] For example, three cutting edges and a drill or drills and taps or any other combination of fixed and / or circumferentially effective processing bodies may be provided at an angle of attack of 70 °. With such a geometry, a relatively large clearance remains in the axial region around the shift axis. Here, for example, a central, with the switching axis coaxial machining body such as drills or cutters can be provided.

Of course, regardless of this, a plurality of processing bodies could still be provided on the turret on a second conical surface.

According to a third independently advantageous aspect of the invention, the stated object solves a turret tool carrier with a connection area and a work area, wherein the connection area is set up in particular for connection to a combined turn-mill spindle and wherein the work area a plurality of Has Schneideisenaufhahmen, which are switchable about a switching axis, wherein in the work area, a drill chuck is provided for receiving a drill at an angle to the indexing axis.

According to this aspect of the invention, the chuck is provided in the working area such that the Aufhahmeachse the drill chuck and thus the position of the longitudinal axis of a aufhehmbaren there drill is not parallel to the indexing axis. Conceptually, it should be made clear that the "angle" should not be equal to 0. The indexing axis generally corresponds to the axis of rotation of the combined turning-milling spindle, in particular if the turret tool carrier is designed for working in confined spaces.

[35] Especially in confined spaces, it will often be advantageous if the turning-milling spindle can be moved in a vertical position into the processing space inside. In order to provide a rotating part with a bore, the turning-milling spindle must the drill in a suitable position turn on the turned part. However, the axis of rotation of a rotating part in a turning-milling machine is usually perpendicular to that direction from which turning-milling spindles can dip into the processing space. In general, the axis of rotation of the rotary member is horizontal, while from above and / or from below turning-milling spindles can be retracted into the processing room.

[36] The greater the angle between the dipping direction of the turning-milling spindle - usually identical to the switching axis - and the drill held on the turret tool carrier, the less the turning-milling spindle must be turned in the processing space to bring the drill in the axis of rotation of the rotating part. In this way, not only the time of Versteilens the turning-milling spindle is saved, but especially the access in very small processing spaces possible. In particular, with a suitable design, it will also be possible for a tool head located on the opposite side on a turning-milling spindle or a tool slide to work simultaneously in the processing space.

Preferably, the chuck is adapted to hold the drill at an angle less than about 20 °, especially less than about 10 °, preferably from about 0 °, to a shift plane perpendicular to the shift axis. Such a constellation corresponds to an approach of the drill to a vertical angle to the indexing axis or a precise arrangement of the drill at a vertical angle to the indexing axis, so that the rotary milling spindle after retraction into the processing space only very little and preferably not be pivoted got to.

Regardless of the orientation of the drill can be held by the drill chuck, it is proposed that a Schneckenisenaufhahme is adapted to take a die at least approximately parallel to the indexing axis. This idea is based on the recognition that cutting blades are usually turned radially to a rotating part. If it is assumed that the conventional constellation in which a rotary member is rotated about an axis of rotation and a rotary milling spindle in a direction perpendicular thereto can be moved into the processing space, this allows a hiring of the cutting iron to the rotary member without the rotation Milling spindle must be swiveled.

[39] Preferably, the Schneckenisenaufhahmen are arranged with the drill chuck in a regular switching angle. In this way can be changed by simply switching the turret tool carrier between the dies on the Schneckenisenaufhahmen and the drill in the drill chuck without much time delay.

[4O] In a preferred constellation, the turret tool carrier has a carrier core to which the cutting iron attachments are attached and which itself supports the drill chuck and the connecting piece. has area. Such a turret tool carrier is very compact and can be variably equipped with different carrier cores for different dies.

[41] The above-described designs of turret tool carriers are particularly advantageous when the turret tool carrier is connected to a turning-milling spindle, which is intended to be freely adjustable in the processing space on a turning-milling machine , Such arms are often referred to as robotic arms. In such freely movable arms, preferably with six degrees of freedom within the processing space, machining bodies can be arranged at equally free angles on the turret tool carrier. Among other things, this makes it possible to provide a hitherto unachieved number of machining bodies directly on the tool carrier. Sometimes, workpieces can be completely machined without the tool having to be changed.

[42] Regardless of how many degrees of freedom the lathe-mill spindle has, a very high degree of flexibility in the machining of workpieces can be achieved if the lathe-mill spindle can grip the turret tool carrier as required. Thus, not only can conventional tools be used in addition to the tool according to the invention, but in particular also several such revolver tool carriers can be provided.

[43] According to a fourth aspect of the invention, the object solves the use of a chuck as an adapter with a drill chuck for attaching a circumferentially effective processing body to a Schneidaufhahme a turret tool carrier, which is adapted for connection to a combined turning-milling spindle.

[44] It should be emphasized that such a chuck can be used independently as an invention, if it has a Anschließbereich and also exclusively a drill holder. The attachment area is then adapted to be received by a die holder on the revolver. On machining bodies only drills are accepted, but not about additional dies.

[45] It has already been explained that conventional turret tool carriers, which are designed for connection to a combined turning / milling spindle, only offer shots for cutting tools. For circumferentially effective processing body so far the particular great benefit was not recognized when used on a turret on a spindle. Now, it is proposed here that an adapter is attached to a conventional turret tool carrier at that connection point which is intended for a turning tool, instead of the turning tool. This in turn is designed to carry a drill in a chuck. For example, such an adapter may be a compact unit, which has four screw holes in the edge area to be attached to a receiving surface of a cutting steel holder. At the same time, the chuck would then be provided between the screw holes for clamping a drill. In this way, the advantages of the first aspect of the invention can be achieved even with conventional turret tool carriers.

It is understood that a turret tool carrier, which is constructed according to the invention presented here, its beneficial effect unfolds particularly well when it is arranged in a circumferentially effective processing body, so that there is a complete tool.

It is also understood that the use of a chuck adapter on a turret tool carrier of conventional type also has a particularly good effect when the chuck is connected to the turret tool carrier and the chuck of the adapter allows, instead of a cutting iron on a recording of the turret tool carrier to provide a drill or other circumferentially effective machining body.

[48] Furthermore, it is understood that the above-described inventive tools can be used particularly advantageously when a complete turning-milling machine with a combined turning-milling spindle is present in a processing space and if just at that turning-milling spindle such a turret tool carrier is arranged operatively. The turning-milling spindle should be as free as possible in the processing room.

[49] For particularly fast machining steps, it is proposed that in addition to the turning-milling spindle with the turret tool carrier, a lower turret be provided in the machining area.

[50] The invention will be explained in more detail below with reference to three exemplary embodiments with reference to the drawing. Functionally identical components can bear the same reference numerals. Show it

FIG. 9 schematically shows a section through the turret tool carrier from FIG. 8 according to the marking IX-IX there.

The processing space 1 of the turning-milling machine of Figure 1 (not shown in its entirety) is essentially limited by the main spindle 2 and the counter spindle 3, each having a chuck 4, 5 for receiving one or two workpieces (not shown ) exhibit. The two chucks 4, 5 are arranged coaxially about a machine rotation axis 6. For carrying workpieces a provided at the bottom of the processing room 1 tool carriage 7 carries two different dies 8, 9. The carriage 7 is the processing room one or two-dimensional travel, so that the dies 8, 9 to a rotating in the processing chamber 1 about the main spindle axis 6 Workpiece can be employed.

[52] In addition to or without the tool carriage 7, a combined turning-milling spindle 10 is arranged on the machine. A spindle arm 11 can be made in any number of degrees of freedom high precision arbitrarily to a workpiece. At a connection head 12, a turret tool carrier 13 is connected to the rotary-milling spindle 10. For this purpose, this has on an elongated body on a clamping shaft 14, which serves as a connection area to the machine, more precisely to the turning-milling spindle 10. On a head 15 of the turret tool carrier 13, a plurality of receptacles (not shown in detail) for processing bodies 17, 18, 19 are provided within a work area 16.

[53] In the head 15 or in the working area 16 of the turret tool carrier 13 four receptacles for processing bodies are provided, which each carry a processing body 17, 18, 19. These include a drill 17 and two dies 18, 19, wherein the cutting iron 18 is located in the viewing direction exactly in front of a third die and thereby visually obscured. [54] The four processing bodies 17, 18, 19 are arranged parallel to a switching axis 20 of the turret tool carrier 13 and are each offset by a switching angle of 90 ° at the same distance to the switching axis 20. The switching axis 20 is coaxial with the spindle axis the turning-milling spindle 10, by simply turning the connection 12 of the turning-milling spindle 10 by 90 °, the turret tool carrier 13 can be further rotated by just 90 ° per switching operation and thus between the four processing bodies 17, 18, 19 can be switched optionally. Thus, by switching the turret, the tool 13, 17, 18, 19 can be switched gradually from the cutting iron 18 to die 19 for non-visible die to drill and so on rotation.

[55] In operation, one of the cutting dies 18, 19 can be set against a rotating workpiece so that arbitrary filming can be performed on it. Subsequently, the arm 11 of the turning-milling spindle 10 can be moved into the processing space 1 in that a receiving axis 21 and thus the drill 17 is coaxial with the axis of rotation 6. Now, if the workpiece is kept in rotation, with the - even fixed - drill 17 easily an axial bore can be introduced into the workpiece.

[56] To accommodate the drill 17, a chuck 22 (not shown in more detail) is provided as a connection in the axial turret 15.

Thus, the rotary-milling spindle 10 can be used both for drilling operations with the drill 17 and for turning operations with the dies 18, 19 as a fixed tool. In contrast, it has hitherto only been known to rotate such freely engageable turning-milling spindles for drilling.

[0002] Rotary drills, S-shaped boring bars, milling machines such as gear hobbing or cylinder grinders are usually provided on such turning-milling spindles. These are conventionally arranged coaxially in the spindle axis 20 and are used in rotation for working. If, instead, a turret tool carrier 13 is connected to the arm 11 of the turning-milling spindle 10, so far only such tools are found on the head of the turning-milling spindle 10, which are not circumferentially effective processing body. For operations with these processing bodies, the turning-milling spindle is used as a stationary tool while the workpiece is driven by the main and / or sub-spindles 2, 3.

An assembly of the type described above with, for example, three blades 18, 19 and a drill 17 is for example particularly advantageous when a stainless steel workpiece is to be processed. Depending on the processing steps and material quality of the workpiece or tool is A cutting edge often wears out after about ten parts, while a drill can possibly process a larger number of workpieces. For such purposes, it is therefore advisable to weight the available number of shots for processing body in the working area 16 of the turret tool carrier 13 numerically.

In another embodiment, in the spindle and indexing axis 20 of the turning-milling spindle 10 or the axial turret tool carrier 13, a central circulating effective machining body, such as a drill or a tap, be provided, so that the rotation Milling spindle 10 can also be operated as a rotating tool.

The embodiment of the rotary-milling spindle 10 with radial turret in Figure 2 also carries a turret tool carrier 13 ', but the Aufhahmeachsen (exemplified with 21') of the images (exemplified with 22) to the switching axis 20 arranged radially , Thus, the three on the radial turret 13 'switchable cutting iron 18, 19 (the third cutting iron is hidden by the head 15') radially aligned to the switching axis 20, as well as the drill 17th

[62] Such a constellation has the advantage that the spindle arm 11 does not have to be moved completely into the processing space 1 for an axial bore in the workpiece. Rather, it can be made laterally to the axis of rotation 6, so that enough space can remain for the lower tool carriage, in turn, make a machining on a second or the same workpiece.

[63] Radial and axial recordings can also be combined on the turret 15, 15 '. For this purpose, the turret can have axial and radial recordings. Alternatively and cumulatively, with a suitable design, it is possible to fasten a chuck for exactly one drill to a cutting iron receptacle, wherein such a chuck can hold the drill at an angle to the receptacle.

[64] For this purpose, for example, the chuck adapter 50 in Figures 3 and 4 is suitable. This is made in one piece and consists of a Anschließbereich 51 and moreover a Bohrerhalte- tion 52 for a drill 53. The drill can via a clamping screw 54 on the chuck 50th be stretched.

For operation, the chuck adapter 50 is attached with its Anschließbereich 51 on a Schneilisenaufhahme on the turret. The Anschließbereich is provided for this purpose and in its dimensions and fasteners such as screw holes specially aligned for this purpose.

[66] The further embodiment variant of the turret tool carrier 13 "according to the invention in FIGS. 5 to 7, like the turret tool carriers 13, 13 ', consists essentially of FIGS. 1 and 2. Chen from a body 31 with a clamping shaft 14 as a connection area and with a working area 16th

[67] In the working area 16, the turret tool carrier 13 "is formed into a hemispherical turret 15". On revolver head 15 "five circumferentially effective processing bodies 32, 33, 34, 35 are respectively received in chucks in five processing body receptacles (not shown in detail) .These processing bodies are various drills or tappers.The drill 33 is a central drill coaxial in the shift and Spindle axis 20 of the turret tool carrier 13 "or the spindle 10 is arranged. In addition, four drills 32, 35, 34 are arranged in a respective switching angle of 90 ° so that they lie in the lateral surface of a truncated cone around the switching and spindle axis. In this case, a drill is concealed by the drill 35 located at the forefront in FIG. 2 and by the central drill 33.

[68] The central drill has an angle of attack of 0 °. The remaining four drills have an angle of attack of about 45 °.

[69] In the operation shown in Figure 6, the spindle head 11 is moved so in the working space 1, that the drill 32 can be brought into working engagement with a rotary member 37 with bore 38.

[70] When the spindle 10 is fixed in this manner and the rotary member 37 is rotated around the rotation axis of the main spindle 2, any desired axial holes can be made in the rotary member 37 with the self-fixed drill 32.

[71] By simply switching the turret tool carrier 13 "by 90 ° in each case, the three other obliquely arranged drills 34, 35 (one is hidden) can be placed either in the axis of the rotating part 37.

The central drill 33 can be placed in the position of the spindle 10 shown in Figure 7 in the axis of the rotary member 37, for which, however, it is necessary that the spindle arm 11 is moved quite far into the processing space 1, which may can lead to very tight spaces. This also makes it clear with what small space requirements a spindle 10 can make do with the turret tool carrier 13 "according to the invention, when it is tilted as shown in FIG.

It is understood that instead of a ball turret 15 "and chuck adapter can be used, which have an oblique angle between Anschließbereich and drill holder. The further embodiment variant 13 "in FIGS. 8 and 9, like the turret tool carriers 13, 13 ', 13" from FIGS. 1, 2, 5, 6 and 7, essentially consists of a body 31 with a clamping shaft Connection area and with a work area 16.

[75] In the working area 16, the turret tool carrier 13 '"has a cubic carrier core 54 next to it, which is connected directly to the body 31.

The cubic carrier core 54 has four sides 55, 56, 57, 58 each have a receptacle for a processing body. On three sides 55, 56, 57, these are designed as cutting iron mounts, so that the dies 59 can be held there directly or via a Aufhahmemittler 60 there parallel to the indexing axis 20.

[77] A drill chuck 61 is provided in the carrier core 54 on the fourth side 58, which can accommodate a drill 62 for operating the turret tool carrier 13 ". The drill 62 is held perpendicular to the indexing axis 20 by the carrier core 54, while the cutting dies 59 (In the example shown, only one die is attached) parallel to the indexing axis 20 in the direction of the processing space of the turret tool carrier 13 '"projecting.

[78] In the operation of the turret tool carrier 13 '", it is preferably conceivable that there are three turning steels 59, namely one each on the sides 55, 56, 57 of the carrier core 54 provided therefor, and the drill 62.

[79] In the constellation shown, it is advantageous if the turret tool carrier 13 '"is at least substantially perpendicular to the axis of rotation of the rotary member and moved into the processing space, so that it with a lower turret or a lower tool slide as the carriage 7 spatially does not conflict in Figures 1 and 2. As soon as the turret has to be tilted, the upper turning-milling spindle may take up too much space.

[80] The combination of drills and dies is also an advantage, as turning tools are often required in one machining cycle, for example for parting off, roughing and / or smoothing. Liermann-Castell P020S8WO2
