Problems solved by technology

The disadvantage of firmly welded cutting edges is that, in the case of wear, the entire basic body has to be refitted as a whole at the manufacturer, while the cartridges, although replaceable, have to be adjusted individually to the common cutting circle
With this conventional structure, the tool design, the design of the flute shape and the coolant supply are very strongly dependent on the machine tool and the tool and are often not optimally selected

Embodiment Construction

[0030] exist figure 1 The face milling tool 10 shown in includes a tool head 14 rotatable about its central axis as tool axis 12 and a replacement ring 18 equipped with a plurality of cutting elements or cutting plates 16 which are positively placed on the tool head 14 and is detachably fastened at the flange 20 on the front side of the front side.

[0031] as in the same figure 2 As can be seen in the figure, the tool head 14 as an insert milling tool 14 has a rear-side interface 22 for coupling to a milling receptacle not shown; at this the tool head is held in a rotationally fixed manner via an axial screw connection. Alternatively, the replacement ring 18 can likewise be screwed directly onto a special receptacle (not shown) in a one-piece construction.

[0032] Distributed in the peripheral direction on the rear side of the annular front flange 20 are arranged stepped bores 26 for supporting fastening screws 28 on the top side for replacing the ring 18 .

Abstract

The invention relates to a tool head (14) which is rotatable about a tool axis (12) and which can be coupled to a machine tool spindle on its rear side, a large number of tools arranged distributed around the tool axis (12) on a cutting circle A cutting element (16) for milling of a workpiece and a milling tool for a channel system (60) extending through a tool head (14) for a coolant supply to the cutting element (16). According to the invention it is proposed that the replacement ring (18) equipped with the cutting element (16) is positively placed on the front face flange (20) of the tool head (14) and detachable there. fixed.

Description

technical field [0001] The invention relates to a milling tool with a tool head which is rotatable about a tool axis and which can be coupled on its rear side to a machine tool spindle, a plurality of which are distributed on a cutting circle around the tool axis and which are respectively equipped with a front side. A cutting element of the face cutting edge and of the circumferential cutting edge extending angularly thereto for the milling of the workpiece and a channel system extending through the tool head for the coolant supply to the cutting element. Background technique [0002] In the case of milling cutters for high-performance machining (so-called HPC), it is known to mount a large number of cutting elements on the end face of a base body made of steel or aluminum. In this case, the cutting elements are either firmly welded or, however, can be replaced individually in the form of a knife case. The disadvantage of firmly welded cutting edges is that, in the event o...
