The eccentric grinder with an eccentric drive and a drive, which provides a rolling motion of two enagageable gear toothings, has gear toothings provided on the grinding disk and on the housing, respectively of the eccentric grinder. Some toothings are concentrical to the drive shaft, while the toothing on the grinding disk is eccentrically supported relative to the drive shaft. The grinder has at least three different grinding disks, of which one has the gear toothing engageable with one of the toothings on the housing and thus can carry out, due to the operation of the shaft, a predetermined grinding motion. The second grinding disk has a toothing for engaging with another toothing provided on the housing, whereby another grinding motion is obtained. The third grinding disk has no toothing and its grinding motion is obtained from the eccentric drive only and adjusted to a counter pressure force.
