Abstract
The invention relates to a method for machining by grinding or polishing of very thin work pieces which are releasably fastened each to thin carriers. The work pieces are arranged together with the carriers in the recesses of at least on rotor disc of a double sided processing machine and are moved along cycloid paths between the working surfaces of the double sided processing machine. Thereby, the removal rate on the working surfaces of the double sided processing machine is either the same or the removal rate on a working surface is substantially less than the one on the opposing working surface, or on one of the working surfaces no material removal takes place. In one embodiment two work pieces are on carrier, that is, releasably fastened on upper and lower side.
