Abstract
A pot-shaped grinding wheel having a circular grinding region provided with a plurality of segment-like grinding members (5), a circular seat region (4) coaxial with an axially spaced from the grinding region (2), a transition region (3) extending between an inner contour of the grinding region (2) and an outer contour of the seat region (4) and tapering toward the outer contour of the seat region (4), and at least one bore (6) extending parallel to an axis of the grinding wheel and arranged in the grinding region (2) and at least one bore (7) likewise extending parallel to the grinding wheel axis and arranged in the transition region (3).
Claims6
A pot shaped grinding wheel, comprising a circular grinding region (2) having an outer contour and an inner contour and provided with a plurality of substantially segment-shaped grinding members (5) circumferentially spaced from each other and projecting partially beyond the outer contour of the grinding region;
- a circular seat region (4) coaxial with and axially spaced from the grinding region (2) and having an outer contour;
- a transition region (3) extending between an inner contour of the grinding region (2) and an outer contour of the seat region (4) and tapering toward the outer contour of the seat region (4);
- at least one bore(s) (6) extending parallel to an axis of the grinding wheel and arranged in the grinding region (2);
- and at least one bore (7) extending parallel to the axis of the grinding wheel and arranged in the transition region (3).
A pot shaped grinding wheel, comprising a circular grinding region (2) having an inner contour and provided with a plurality of substantially segment-shaped grinding members (5);
