Abstract:
1. A balancing device, comprising: a measuring device for determining a rotational imbalance of a test piece; a spindle unit with a spindle that is embodied to hold the test piece and permit the test piece to rotate at a testing speed; a spindle mount by which the spindle unit is anchored to a base of a machine in a moving fashion so that the spindle unit is able to oscillate in a predetermined measurement direction due to imbalance forces occurring during the measurement operation; at least one sensor, which during rotation of the spindle, detects at least one imbalance variable occurring in the measurement direction; and a material removal device for balancing, the test piece by removing material from a predetermined location; wherein the measuring device and material removal device are embodied so that it is possible to carry out the material removal while the test piece is being held in the spindle; and further comprising: a spindle locking mechanism, which makes it possible to immobilize the spindle unit without a force produced by this immobilizing action exerting any stress on the spindle mount or at least without this force exerting any stress on the sensor or sensors so that the forces generated by the material removal device do not cause the spindle unit to move.
