Abstract
An eccentric plate grinder has a housing, a driving shaft with an eccentric at one end and a grinding plate, on which abrasive paper is fixed, powered by the eccentric. The grinding plate and the driving shaft are joined together by way of a transmission so that the path of any given grain of abrasive material on the grinding plate will be cycloidal and not in a simple circle.
