Abstract

A cutting disk for workpieces, particularly workpieces of fiber-reinforced composite materials, has a base body which is provided at least in some areas with a circumferential toothing and with a flank toothing arranged on at least some areas and on at least one lateral surface. At least with the majority of circumferential teeth, the main cutting edges do not directly encounter the main cutting edges of the adjacent flank teeth, and the main cutting edges accordingly do not define a common rake face.

Claims

1. A cutting disk for cutting and/or making grooves in workpieces, comprising: a disk-shaped base body which is provided at least in some areas with a circumferential toothing and with a flank toothing which is arranged on at least some areas of the base body and on at least on one lateral surface of the base body, wherein with at least a majority of teeth of the cutting disc, main cutting edges of the teeth of the circumferential toothing do not directly encounter main cutting edges of the flank toothing such that the main cutting edges of the teeth of the circumferential toothing and the main cutting edges of the teeth of the flank toothing do not form a common rake face.

2. The cutting disk according to claim 1, wherein the teeth of the circumferential toothing and the teeth of the flank toothing each have at least one secondary cutting edge, wherein the secondary cutting edges do not participate in a machining process.

3. The cutting disk according to claim 1, wherein the flank toothing is arranged in a radially outer area of the base body of the cutting disk.

4. The cutting disk according to claim 3, wherein the flank toothing has identical flank teeth or groups of identical or different flank teeth.

5. The cutting disk according to claim 4, wherein the flank teeth are arranged in groups and wherein the groups of flank teeth are arranged with differently formed flank teeth to adjoin one another without gaps or to be spaced apart from one another.

6. The cutting disk according to claim 1, wherein the base body is provided with the flank toothing on both lateral surfaces, wherein the flank toothings of the two lateral surfaces are configured differently or identically.

7. The cutting disk according to claim 1, wherein the flank toothing is configured such that a free surface of a flank tooth transitions into a gullet space of a next flank tooth.

8. The cutting disk according to claim 1, wherein notches or cutouts are arranged at an outer circumference of the cutting disk.

9. The cutting disk according to claim 1, wherein the circumferential toothing is formed by identical circumferential teeth or by groups of different circumferential teeth.

10. The cutting disk according to claim 1, wherein the main cutting edges of the circumferential teeth are arranged at an angle to an axial direction of the cutting disk.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The cutting disk 10 in FIGS. 1, 1a has a base body 11, a gapless circumferential toothing 12 and a gapless flank toothing 13. The flank toothing 13 is located in the outer radial area of the base body 11 and directly adjoins the circumferential toothing 12. The rotational direction of the cutting disk 10 and of the cutting disks in the other figures is indicated in each instance by an arrow D.

[0026] The detail view of the toothing of the cutting disk 10 in FIG. 2 looking at the opposite lateral surface shows that the base body 11 is also provided with a flank toothing 14 on its opposite lateral surface. The detail view in FIG. 2 further shows that the circumferential toothing 12 is formed by a plurality of circumferential teeth 12.1, and every circumferential tooth 12.1 has a main cutting edge 12.1a and two secondary cutting edges 12.1b. The flank toothing 13, on the other hand, is formed by a plurality of identical flank teeth 13.1 having a main cutting edge 13.1a and a secondary cutting edge 13.1b. Also, teeth 14.1 of flank toothing 14 are provided in each instance with a main cutting edge 14.1a and a secondary cutting edge 14.1b. The main cutting edges 12.1a of the circumferential toothing 12 and the main cutting edges 13.1a and 14.1a of the flank toothings 13, 14 have no common intersection. Rather, they are spaced apart by a spacing Tr. This makes it possible to select the cutting angles of the main cutting edges 12.1a of the circumferential toothing 12 and the cutting angles 13.1a, 14.1a of the flank toothings 13 and 14 completely independently from one another and, accordingly, to adjust optimal cutting edge angles for all three toothings 12, 13 and 14. Further, it will be appreciated from FIG. 2 that none of the secondary cutting edges 12.1b, 13.1b and 14.1b in cutting disk 10 participate in the machining process.

[0027] FIGS. 3 and 4 show a further variant of a cutting disk 20 in which a flank toothing 21 is divided into different groups 22, 23 according to FIG. 3, wherein teeth 22.1 and 23.1 of groups 22 and 23 differ with respect to the orientation of their main cutting edges 22.1a and 23.1a.

[0028] A circumferential toothing 24 of cutting disk 20 is also divided into different groups 25, 26 as is illustrated in FIG. 4. Teeth 25.1, 26.1 of groups 25 and 26 also have different orientations of the main cutting edges 25.1a and 26.1. In cutting disk 20, groups 22, 23 of flank toothing 21 and groups 25, 26 of circumferential toothing 24 are arranged adjacent to one another without gaps. However, this is not compulsory. They could also be arranged so as to be spaced apart from one another.

[0029] FIG. 5 shows a third embodiment form of a cutting disk 30 which corresponds to cutting disk 20 with respect to its flank toothing 31 and its circumferential toothing 32. However, cutouts 33 which are intended to counteract overheating of the workpiece during the cutting process are provided at regular intervals along the circumference of cutting disk 30.
