Processing machine for the surface treatment of workpieces having a push rod which can be reciprocated connected with a processing tool and put in motion by a driven eccentric drive assembly, the throw of the eccentric being adjustable by rotation of an eccentric casing. The processing result is improved by an oppositely acting eccentric mass balance assembly attached to the eccentric drive assembly which eliminates the undesired effect of the unbalanced forces, thereby providing quiet operation of the processing machine. |
