A means is described for milling of the thread tops in a screw press. The means is characterized in that it comprises guide rails (10) for mounting in a housing section (1) of a screw press, along opposing sides of the press. It includes a slide (12) in each guide rail (10), an arcuate carrier (11) conforming to the curvature of the thread top, which spans the screw press between the guide rails (10). The means further includes a trolley (13) in the carrier (11) for movement along the curve, a holding device (13, 24, 25, 32, 27) for a grinding apparatus (14) in the trolley and guide means (44) on the trolley, for guiding it and the carrier along a thread flank. |
