Definitions
- the invention relates to a tool for machining an outer peripheral surface of a workpiece.
- Workpieces that have a large outer diameter, in particular of more than 170 mm, with a large overhang length, in particular of at least 0.8 times the outer diameter, are typically machined by turning, in particular on turning/milling centres.
- This is particularly disadvantageous with regard to an overall production strategy for the production of complex components, in particular stator housings for electric motors, since a great deal of time and money is required, in particular with regard to the use of different processing stations and the re-clamping of different ones, in particular for internal processing and on the other hand for external processing tools.
- the inner diameter of such workpieces can typically be machined with rotating tools on a machining center, which allows rapid and, in particular, automated re-clamping.
- the object is achieved in particular by creating a tool for machining an outer peripheral surface of a workpiece that has an interface that is set up for fastening the tool to a counter-interface.
- the tool also has a base body that is at least partially cylindrical.
- the base body has a peripheral wall that encompasses a receiving space and is designed to be open at the end, so that the workpiece can be received at least partially in the receiving space.
- At least one cutting edge, which engages in the receiving space, is arranged on the base body for the machining of the outer peripheral surface of the workpiece.
- the peripheral wall has at least one chip passage opening, which is arranged relative to the at least one cutting edge in such a way that chips removed by the at least one cutting edge during machining of the workpiece can exit through the at least one chip passage opening from the receiving space into an external environment of the base body.
- the base body which is cylindrical at least in sections, gives the tool a high level of stability, so that large outside diameters can be machined with high quality even with large overhang lengths, in particular also fine machined (at least IT7 quality and better).
- the machined workpiece can be accommodated during the machining in the receiving space open at the end, with the tool encompassing the workpiece with the peripheral wall at least in regions.
- the tool is thus designed in particular as a tubular or bell-shaped tool, which entails intrinsically high stability.
- the outer peripheral surface of the workpiece, and consequently the outer diameter can be machined.
- the resulting chips can escape radially outwards through the chip passage recess assigned to the cutting edge, so that damage to the workpiece surface, in particular the outer peripheral surface of the workpiece, by chips arranged, in particular jammed, between the outer peripheral surface of the workpiece and the peripheral wall of the tool is effectively avoided.
- this ensures a very high processing quality in connection with the high stability of the tool.
- the chip clearance recess advantageously reduces the weight of the tool, which has a positive effect affects the machining accuracy with large overhang lengths.
- a counter-interface in particular a machine spindle, particularly preferably a machining center, it being possible in particular to carry out rotating machining of the workpiece in such a way that either the tool or the workpiece rotates around a imaginary longitudinal axis of the tool is rotated, or that both the tool and the workpiece are rotated relative to each other about the longitudinal axis of the tool.
- the tool proposed here allows a pot-shaped stator housing for an electric motor to be completely machined on a single machine, in particular a machining center.
- Both the inner diameter, ie an inner peripheral surface, and the outer diameter, ie the outer peripheral surface, of the cup-shaped stator housing can be machined on the same machine, in particular the machining center.
- the interface is designed as a hollow shank taper interface, as a steep taper interface, as a Morse taper interface or in some other suitable manner.
- an axial direction or longitudinal direction is understood in particular as meaning a direction that extends along a longest extent, preferably along a symmetry or rotational axis of the preferably cylindrically symmetrical, in particular rotationally symmetrical, tool.
- a radial direction is perpendicular to the axial direction.
- a circumferential direction encompasses the axial direction concentrically.
- the tool has exactly one cutting edge. In another preferred embodiment, the tool has a plurality of cutting edges. In a preferred embodiment, the tool has exactly one chip passage recess. In another preferred embodiment, the tool has a plurality of chip passage recesses.
- the base body is circular-cylindrical or rotationally symmetrical.
- the base body is tubular.
- the at least one cutting edge is arranged on the peripheral wall of the base body.
- the at least one blade has in particular a geometrically defined or geometrically determined cutting edge.
- the at least one cutting edge is designed as a blade insert, cutting insert or indexable insert, which has at least one geometrically defined or geometrically determined cutting edge
- the at least one cutting edge is in particular in machining engagement with the outer peripheral surface of the workpiece when the workpiece is at least partially received in the receiving space.
- the tool has a plurality of cutting edges as the at least one cutting edge, the peripheral wall having a plurality of chip passage openings, and wherein each chip passage opening of the plurality of chip passage openings is assigned at least one cutting edge of the plurality of cutting edges in such a way that that chips removed by the respectively assigned cutting edge can escape from the receiving space into the external environment through the assigned chip passage recess. It is possible that exactly one cutting edge of the plurality of cutting edges is assigned to each chip passage opening of the plurality of chip passage openings. However, it is also possible for a plurality of cutting edges, in particular at least two cutting edges, to be assigned to at least one chip passage recess of the plurality of chip passage recesses.
- each cutting edge of the plurality of cutting edges is preferably one--in particular exactly one--assigned to a chip passage recess, so that the A plurality of cutting edges, the chips removed by the respective cutting edge can exit through the associated chip passage recess in the radial direction into the external environment. If the tool has a plurality of chip passage recesses, this advantageously also reduces the weight of the tool, which last but not least also takes into account the idea of lightweight construction.
- the at least one chip passage recess is designed to be closed along a closed recess peripheral line.
- the pocket perimeter extends around a radius vector that is perpendicular to the axial direction of the tool and penetrates the chip clearance pocket. So it is in the recess perimeter to a the perimeter of the
- the term “circumference” here therefore refers to the circumference of the chip clearance recess and not to the tool circumference.
- the at least one chip passage recess is designed in particular as a window in the peripheral wall.
- Circumferential wall and / or material of another tool part such as a front cutting ring, in particular completely framed.
- a front cutting ring Circumferential wall and / or material of another tool part, such as a front cutting ring, in particular completely framed.
- the peripheral wall has at least one additional recess.
- the at least one additional recess advantageously contributes to a further reduced weight of the tool, so that it can be made particularly light. This particularly takes into account the idea of lightweight construction.
- the additional recess is assigned to the additional recess--in contrast to a chip passage recess.
- the additional recess is therefore in particular free of a cutting edge.
- the additional recess is not used for the passage of chips.
- the at least one additional recess extends through the peripheral wall.
- the receiving space is open to the outside environment in the area of the additional recess.
- This configuration results in a significant weight reduction for the tool.
- the additional recess is preferably closed towards the receiving space, or towards the external environment of the tool, or on both sides.
- An additional recess closed on both sides can be produced in particular by means of a generative or additive manufacturing process.
- the peripheral wall is thinned out in the area of the additional recess, ie its wall thickness is reduced.
- the peripheral wall also has a finite wall thickness in the area of the additional recess.
- the additional recess is designed as a pocket in the peripheral wall.
- the additional recess has a base that separates a volume of the additional recess from the receiving space or from the outside environment. The at least one additional recess closed towards the receiving space also leads to a considerable weight reduction for the tool, which at the same time has significantly greater stability than if the additional recess penetrates the peripheral wall.
- the peripheral wall has at least one additional cutout extending through the peripheral wall and at least one additional cutout that is closed at least on one side.
- the various configurations of the additional recess can therefore also be advantageously combined with one another, in particular in order to simultaneously reduce the weight of the tool and increase its stability.
- the at least one cutting edge is positioned on a cutting circle with a diameter of at least 170 mm and at most 300 mm, preferably at least 180 mm and at most 280 mm, preferably at least 190 mm and at most 270 mm, preferably from at least 200 mm to a maximum of 260 mm.
- the tool is thus advantageously set up in particular to machine workpieces with a large external diameter.
- the receiving space has a length from an end face on the opening side to a bottom surface—opposite the end face on the opening side in the axial direction—which is multiplied by the flight circle by a factor of at least 0.8 to at most 3.5, preferably from at least 2 to at most 3, preferably from at least 1.5 to at most 2.5.
- the tool is thus set up in particular to machine workpieces with a large overhang.
- the end face on the opening side is in particular arranged opposite the interface in the axial direction.
- the receiving space is open in the area of the end face, so that the workpiece can be inserted into the receiving space from the end face on the opening side.
- the end face on the opening side encompasses an opening in the receiving space, through which the workpiece can be introduced into the receiving space.
- the bottom surface is longitudinally arranged on the interface side.
- the interface is preferably formed in one piece with the bottom surface or is connected in several parts.
- the tool has at least one first cutting edge and at least one second cutting edge as the at least one cutting edge, the at least one first cutting edge being arranged offset relative to the at least one second cutting edge in the axial direction of the base body.
- the at least one first cutting edge is assigned a first cutting circle, which differs from a second cutting circle assigned to the at least one second cutting edge.
- the at least one first cutting edge and the at least one second cutting edge are therefore not only offset axially, but also radially with respect to one another. This advantageously allows a stepped external machining of the workpiece, in particular the simultaneous or sequential machining of a plurality of different external diameters on the same workpiece.
- the base body and the interface are designed in multiple parts and are connected to one another. This advantageously makes it possible, in particular, for the interface to be able to be manufactured separately from the base body, in particular from a different material. As a result, in particular for the interface, greater rigidity and/or stability can be provided than for the base body, which is advantageous since greater forces typically act in the area of the interface; at the same time, the base body can be designed to be light and yet stable.
- the interface is connected to the base body, in particular to the bottom surface, in a form-fitting, force-fitting and/or material-fitting manner.
- the interface is preferably screwed to the base body, in particular to the bottom surface.
- the interface is formed in one piece, preferably of the same material, with the base body.
- the base body has a first material, with the interface having a second material.
- the first material is a different material than the second material.
- the base body and the interface therefore have in particular different materials from one another or consist of different materials from one another. This advantageously allows the choice of material to be optimized for the interface on the one hand and for the base body on the other with a view to the various desired properties. In particular, increased rigidity and/or stability can be provided for the interface, with the base body being able to be made light and stable at the same time.
- the first material has a lower density than the second material.
- the base body can thus be designed to be particularly light.
- the interface can be designed to be particularly rigid and/or stable.
- the first material is a light metal and the second material is steel.
- the first material is preferably aluminum or an aluminum alloy. The appropriate choice of material allows in a special way a stiff and/or stable design of the interface with a light and stable design of the base body at the same time.
- a cutting ring having at least one front cutting edge is arranged on the opening-side end face of the base body.

- the at least one face cutting edge is designed as a blade insert, cutting insert or indexable insert, which has at least one geometrically defined or geometrically determined cutting edge
- the cutter ring is designed in multiple parts with the base body and is connected to the base body. In this way, the choice of material for the blade ring on the one hand and the base body on the other hand can advantageously be optimized in relation to the properties required in each case.
- the cutter ring has a third material that has a higher density than the first material of the base body.
- the blade ring can thus advantageously be made more stable and/or stiffer than the base body.
- the cutting ring preferably additionally contributes advantageously to the overall stability of the tool.

- the third material is steel.
- the cutting ring has at least one chip removal groove assigned to the at least one front cutting edge, which is arranged and designed in such a way that chips removed from the at least one front cutting edge via the chip removal groove assigned to the front cutting edge, in particular in the radial direction - and/or in the axial direction in the direction of the interface - can be discharged.
