Definitions
- the invention relates to an indexable insert for a milling tool for machining of workpieces, which is mounted radially on a milling head on a rotationally symmetrical Y-axis on the milling head.
- Milling with rotating blades is a method known for years, but which has prevailed only to a small extent in manufacturing.
- a tool is used whose active element consists of a round, rotatably mounted cutting disc, which performs a kinematically related automatic rotational movement during the machining process by the cutting process and the inclination of the cutting disc axis to the cutting direction.
- active element consists of a round, rotatably mounted cutting disc
- a corresponding cutter is known for example from DD 118 543 here.
- a fixed cutting edge is provided on the milling head in addition to a rotating hub, in order to achieve a special sectional image in this way.
- Another embodiment of the prior art is also known from US 2,885,766, in which the cutting head rotatably mounted indexable inserts are provided which are rotatably mounted on rotationally symmetrical axes on the milling head.
- the rotatably mounted indexable inserts are in this known from the prior art milling head in U-shaped nests, so that in particular a two-sided integration of the axes is given in the milling head.
- a rotatable blade which has on its rear side via an integrally formed shaft which is rotatably mounted in the carrier material of the milling head in a blind hole.
- An equivalent solution is also known from DE 10 2005 051 695, in which in particular the indexable insert is fastened to a carrier element and wherein the carrier element is rotatably mounted in the tool.
- the support member coaxial with the Y-axis to a stub shaft, which is rotatably guided in a blind hole in the tool.
- the support element can be actively formed rotationally driven, so that due to the rotational movement of the milling tool, here provided via a milling head gear, the mounted on the support insert is driven ,
- a corresponding embodiment is also described in CH 480 120.
- Milling tools that are equipped with rotatably mounted cutting discs, it is considered disadvantageous that build the known embodiments with respect to their rotatably mounted indexable inserts very expensive, which is due to the elaborately designed storage for the indexable insert.
- all known in the prior art solutions own that in particular the rotatably mounted indexable insert can be changed that several interventions must be made on the milling head to solve the indexable insert on the one hand from the milling head or the indexable insert after loosening the Carrier agent is still to be solved by the carrier itself.
- indexable inserts must be kept, which are particularly adapted to the milling head.
- the invention thus raises the problem of providing an indexable insert for a milling head for machining workpieces, which is mounted radially rotatably, wherein its configuration for supporting the cutting much simpler fails and in particular the change process of the cutting plate designed much easier ,
- the advantages achieved by the invention are in particular that due to a pin solution in conjunction with the enclosure of the rotating indexable insert through the carrier material of the milling head in a cage rotating indexable insert is created, which has the sufficient freedom from movement or rotation, on the one hand during the drilling process penetrate into the material and on the other hand can take off a corresponding chip during milling.
- the simple integration of the indexable insert is created here only by the shape of the cutter head in conjunction with the bearing pin. This ensures that the rotating disk has sufficient freedom of rotation, in particular during chip removal, without the risk of the blades being able to lift themselves off their bearings.

- the remote cutting edge can also be provided with a chip recess.
- the indexable insert used in the milling head lies in the milling head such that the cutting edge of the indexable insert is located in a recessed by the enclosed or surrounding material of the milling head area.
- the bordered or surrounding material of the milling head interacts only with the disk surface.
- indexable insert through the support material of the milling head, a rotating insert in a cage is created, which has sufficient freedom of movement or rotation to penetrate the one hand during the drilling process in the material and the other hand when milling a corresponding chip unhindered without caking, be it on the substrate or at the Wendechtplatte itself, can take off.
- the simple integration of the indexable insert is in this case only by the shape of the cutter head in connection PatXML 5/13 P0944
- the bearing pin on its other end a threaded portion with which it is fixed in the material of the milling head.
- the bearing pin is designed such that it has a front cylindrical portion for pivotal mounting of the indexable insert and in its central region a conical region for fixing in the carrier material of the milling head. At the conical region then adjoins arranged for clamping in the carrier material threaded portion, so that the pin can be introduced under a strain in the carrier head, and thus assumes a stable for the free pivotal mounting of the indexable insert bearing axis.
- the tensioning of the bearing pin, the conical training accordingly cooperates with a taper in the Fräskopfmaterial.
- Indexable insert has this a circumferential groove into which engages a arranged on the milling head race or pin.
- the circumferential groove is arranged radially on the indexable insert.
- the circumferential groove is arranged on the rear support or contact surface of the indexable insert.
