Abstract

The device has a displaceable grinding unit, and a translatory drive unit designed to move the grinding unit in a translatory manner. An eccentric shaft is designed to move the grinding unit in a rotary manner, and an oscillating module holds the grinding unit. The module displaces the grinding unit in an oscillating movement, and is moved in a frequency range of 30 to 100 Hertz. The module has upper and lower parts (3, 4) moved against each other. The grinding unit is attached at the lower part of the module.
