"Preassignment tool"

The invention relates to a milling tool, in particular for a device for milling grooves in masonry and the like., With Hessereinserts and with a disk-shaped bearing this Tool body.

The tool body of a known milling tool is made from a suitable workpiece by machining it on all sides produced, in particular undercuts and radial Recesses must be made for the chip space. It It is also common practice to limit the parts of the tool body carrying the Hessereinserts to a correspondingly wide one To be able to produce a groove in masonry or the like.

The invention has a simple production tool body to the target · This object is inventively achieved by the tool body in a side view as seen at the same Dafi

moderate polygonal shape, which has a constant width at least »in the ring area of the heat exchanger, and that the army operations are each in the area of one of the Edges are attached. The tool body can be made from KshrlEasitproiilmaterlal in simpler wines and lü any göwüziöc'ntsü width, with a Sohranking im Bereioh of the army operations can be forbidden. The special arrangement of the Heßer inserts results in a sufficient, the spanxutum. as well as the possibility of the Preisohliffee and the Naohschleifens. The Heeeereineätse are well supported. The The milling tool can be sealed well on the side and it has a better soothing effect during operation than the well-known tools. There is no need to solder a hub.

In a further development of the invention, the tool body has at least one for engagement in the area of its central bore in a drive shaft that supports it. Preferably two are arranged diametrically Pins provided. The presener cannot pull itself out during the working process and is therefore without damage easy to solve. In addition, the milling cutter cannot be placed the wrong way round. The pins can be designed as a predetermined breaking point.

Further advantages of the invention result from the rest Claims, the description and the drawing. In this is a pre-tool ale Ausftthrungsbeispiel the item of the invention shown schematically. Show it

seen as a regular polygon and formed by a polygonal profile material is cut in the desired width. The disk-shaped tool body 1 has in its center a graduated Miitäluöarüüg, döfvu Stages are designated with 2 and 3, the central hole, in level 3 has a larger durometer than in level 2. In the area of level 2 there are two diametrically arranged Driving pins 4.5 attached in the tool body 1 for serve to engage in corresponding recesses of a drive shaft not shown, on which the tool body 1 is to be placed and screwed, with a Nut engages in step 3 of the central hole.

In the region of its edges, the tool body 1 has incisions arranged at an angle to the radial, each serving to accommodate a knife insert 6 which is arranged at an angle of 14 ° to the radial and thus acts like an undercut knife insert. When Ausftthrungabeispiel of FIG. 1, the edge is the tool body ¹ just in back of the blade-holder 6, the projecting edge to the outside in the direction of the direction of rotation indicating arrow A the front. The sea insert 6 can be designed in one piece or consist of two pieces and is preferably connected to the tool body 1 by soldering or gluing.

In the embodiment shown in Fig. 3, the tool body is designated by 1a, the imaginary edge of the tool body is located approximately in the middle of the knife insert 6. In the Pig. 1 is replaced by the be ~ special arrangement of the knife insert 6 on his back well supported »Each knife insert 6 has a * sufficient Chip space. as well as enough space for regrinding.
