A device for transporting an object to and/or from a grinding machine includes a base, a carrier arranged on the base and rotatable with respect to the base about a first axis of rotation, a swivel device arranged on the carrier for transporting the object. The swivel device is pivotable with respect to the carrier about a second axis of rotation, and the device is designed to carry out a rotational movement of the carrier about the first axis of rotation and a swivel movement of the swivel device about the second axis of rotation at least at times simultaneously in such a way that the object can be transported by means of a transport movement of the swivel device resulting from the superimposition of the rotational movement of the carrier with the swivel movement of the swivel device.

A method for dressing a grinding tool includes acquiring information on a deflection waveform indicating a positional deviation of a first tooth surface for each rotation phase of a first rotating body, acquiring, as contact positional data indicating a position where the first tooth surface and the second tooth surface are in contact with each other, an envelope of the deflection waveform, the envelope passing through a plurality of crests of the deflection waveform located on a side closer to a second tooth surface, and dressing a grinding tooth surface with a dresser tooth surface by changing the rotation speed of the first rotating body based on a predetermined forming quantity and the contact positional data.
