Apparatus and method for grinding rotary blades

An apparatus (1) for grinding rotary blades (3) comprising:

• at least one mount (5) for a rotary blade (3) to which the rotary blade (3) can be attached;
• at least one grinding tool (9) having a grinding wheel (29) and a deburring wheel (31),
• wherein the grinding tool (9) and the rotary blade (3) attached in the mount (5) are movable relative to one another such that a blade edge (11) extending at the periphery of the rotary blade (3) can be ground by the grinding tool (9);
• and a pivoting device (33) for the grinding tool (9),
• wherein the pivoting device (33) is designed so that the grinding tool (9) is pivotable about a pivot axis (45) which extends through a grinding point (27) at which the blade edge (11) and the grinding tool (9) contact one another during the grinding process,
• wherein the pivoting device (33) has at least one pivot bearing (35) and an axis of rotation (47) of the pivot bearing (35) coincides with the pivot axis (45) of the grinding tool (9), and
• wherein the grinding wheel (29) and the deburring wheel (31) are each attached to a pivot arm (37, 39), with both pivot arms (37, 39) being attached to the pivot bearing (35) and being rotatable about the common axis of rotation (47) of the pivot bearing (35) for the common pivoting of the grinding wheel (29) and of the deburring wheel (31).
