Definitions
- the invention relates to a milling tool, in particular intended for orthogonal rotary milling of crankshafts, with a base body having chip chambers and with a plurality of cutting elements which can be detachably fastened.
- Milling tools of the type mentioned are known in various embodiments, but they do not meet the requirements placed on them.
- the invention is therefore based on the object of designing a milling tool of the type mentioned in such a way that it satisfies the requirements with regard to cutting behavior, tool life and economy.
- the invention provides with the features of the characterizing part of claim 1 that cutting elements of the same size and shape are provided for primary and frontal work as well as for primary end work and that they are ab ⁇ are alternately arranged on the circumferential side and on the end face.
- a milling tool according to the invention preferably has identically identical cutting elements on its front side and on its circumferential surface adjacent to the front side, which, however, are installed differently in the base body according to their intended purpose, are each provided with main cutting edges and with secondary cutting edges, and alternately with their Main cutting edges are arranged on the end face and, with their secondary cutting edges on the peripheral side or with their main cutting edges on the circumferential side and with their secondary cutting edges on the front side.
- the minor cutting edges are set back in an order of magnitude that corresponds to the feed per tooth.
- FIGS. 4 and 5 a schematic diagram relating to the machining of crankshafts and here in particular the machining of the journal, on the same scale as in FIGS. 4 and
- FIGS. 5 and 5 a schematic diagram of part of a crankshaft belonging to the representations of FIGS. 5 and 5, showing two cheeks and one pin;
- a milling tool 1 comprises a base body 2 with a plurality of chip chambers 3 and / or with detachably attachable cutting elements 5 and 6.
- the cutting elements 5 are each arranged or fastened on the circumference and the cutting elements 6 are respectively arranged or fastened on the end face .
- the cutting elements 5 and the same applies to the cutting elements 6 each have a generally known passage opening 7 for a fastening screw 8, which extends essentially radially in the cutting elements 5, while in the cutting elements 6 it extends essentially parallel to the axis 9 of the milling tool 1 is arranged.
- the cutting elements 5, 6 are each indexable inserts and are the same or identical in size and shape. They are intended both for primary circumferential work and for primary frontal work and each have main cutting edges 10 and secondary cutting edges 11.
- the main cutting edges 10 are significantly longer than the secondary cutting edges 11, the main cutting edges 10 and the secondary cutting edges 11 further delimiting a rectangular area 12.
- the respective corners are preferably rounded, as shown in FIG. 1.
- the cutting elements 5, 6 are each parallelogram-shaped in accordance with the exemplary embodiment and in particular in accordance with the representations in FIGS. 7 to 9 and have a rhombic or rhomboid base area 13. According to the exemplary embodiment, the cutting elements 5, 6 are delimited by the rectangular surfaces 12 which are parallel to one another they limit the main cutting edges 10 or secondary cutting edges 11 on the outside. As an indexable insert, each cutting element 5, 6 has four main cutting edges 10 and four secondary cutting edges 11, wherein, according to the exemplary embodiment, each main cutting edge 10 is also assigned a chip-forming recess 14 as a chip-forming surface.
- the chip mold trough 14 has an exit angle of approximately 25 ° to the plane of the rectangular surface 12 serving as the rake surface, as shown in FIG. 7.
- the secondary cutting edges 11 are each set back 0.1 to 0.5 mm and preferably 0.2 to 0.3 mm with respect to the respective main cutting edges 10. This dimension also corresponds to the respective tooth feed and is indicated in FIG. 1 with the aid of the dimensions U and S given there.
- the rhombic or rhomboid base area 13 serves both as the free area both in the cutting elements 5 and in the cutting elements 6.
- FIG. 3 shows the milling tool 1 when working on a cylindrical body 15.
- the end face 16 of the milling tool 1 faces the peripheral surface 17 of the cylindrical body 15 and processes the cylindrical body 15 on its circumference both with its cutting elements 5 arranged on the circumference and with its cutting elements 6 arranged on the front side.
- the axis 9 of the milling tools 1 is arranged according to FIG. 3 by the dimension X below the axis of rotation 18 of the cylindrical body 15.
- the cylindrical body 15 rotates about its axis of rotation 18 at a relatively low speed and the milling body 1 rotates at a high speed about its axis 9 and also moves in the direction of the two coordinates Y and Z according to FIG. 3-
- FIGS. 4 to 6 show a particularly useful application for a milling tool 1 when machining a crankshaft 20.
- the crankshaft 20 has axle bearing pieces 21, crank cheeks 22 arranged at a distance from one another and at least one bearing journal 23 therebetween. Not only the axle bearing pieces 21, but also the crank arms 22 and the bearing pin 23 have to be machined, the milling tool 1 serving primarily for roughing. 4 and 6, the contour of the crankshaft blank to be machined and the material 25 to be removed with the aid of the milling tool 1 during roughing are indicated by dashed lines 24.
- FIG. 4 also shows the milling tool 1 when working on a first crank web 22 and when removing the material 25 with the cutting elements 5 arranged on the circumference and the cutting elements 6 arranged on the end face, all features being shown in principle in FIG. 4.
- the diameter of the milling tool 1 is also smaller than the distance between the mutually facing crank cheek end surfaces 26 and 27 to be manufactured with the milling tool 1.
- Another milling tool 1a with a larger diameter is preferably used to machine the bearing journal 23 and to produce its contour 28, which corresponds to the distance between the two facing crank cheek end faces 26, 27 (FIG. 5).
- undercuts 29 (dashed semicircles in FIGS. 5 and 6) and the finishing are carried out in crankshaft machining with the aid of further tools, not shown in the figures and of no further interest here.
- the invention is not limited to the machining of shaft shafts and can also be supplemented and varied with regard to further details without deviating from the basic concept of the invention.
