Abstract

The invention relates to an abrasive cutoff wheel which comprises a central disk (2) and a plurality of abrasive segments (4) which subtend between themselves a straight bonding line (10) that slants inward along a predetermined disk direction of rotation (12) toward the wheel center of rotation 14, deviating from a tangent line. Seen in wheel sideview, the radially outer surface (18) of each abrasive segment (4) preferably also is straight and slants inward along the wheel direction of rotation (12) toward the wheel center of rotation (14), deviating from a tangent line.

Claims (5)

1. An abrasive cutoff wheel comprising a central disk (2) and a plurality of abrasive segments (4) distributed along the circumference of the central disk (2) on the same number of disk junction faces (6) that are straight as seen in wheel side-view and that comprise each a segment junction face (8) which is undetachably af-fixed to only one of the disk junction faces (6), characterized in that the abrasive cutoff wheel is driven into a predetermined direction of rotation (12), in that each disk junction face (6) and the segment junction face (8) affixed to it when seen in wheel sideview subtend a straight bonding line (10) which, in the pre-determined direction of rotation (12) slopes inward toward the wheel center of rota-tion (14), deviating from a tangent line.
2. Abrasive cutoff wheel as claimed in claim 1, characterized in that the radially outer surface (18) of each abrasive segment (4) is straight as seen in wheel sideview and defines a straight surface line (20) which slants inward in the direction of the wheel center of rotation (14), deviating from a tangent line.
3. Abrasive cutoff wheel as claimed in claim 2, characterized in that the surface line (20) and the bonding line (10) of the particular abrasive segment (4) are mutually parallel.
4. Abrasive cutoff wheel as claimed in one of the above claims, charac-terized in that the central disk (2) comprises a circumferential notch (22, 24) at every two adjacent disk junction faces (6).
5. Abrasive cutoff wheel as claimed in claim 4, characterized in that the depths of the circumferential notches (22, 24) are different, a deeper circumferential notch (24) and a shallower circumferential notch (22) alternating in the wheel circum-ferential direction.
