ABSTRACT:
A device for the fine adjustment of the cutting depth of a surface milling cutter, where a cutter holder supporting a drive and a cutting head is displaceable with respect to a foot plate along guide columns which extend vertically to the foot plate and are supported therein. The cutter holder is fixable in a first, rough vertical distance position (cutting depth) by means of at least one locking element, with a threaded spindle, which is preferably adjustable parallel to the guide columns. The cutter holder has a stop face, which cooperates with a bit stop, fastened to be adjustable in height on the foot plate, so that a fine height adjustment is possible when the locking element(s) is (are) released. In order to decrease the amount of time and adjustment effort for setting a desired cutting depth by means of the fine height adjustment, it is provided that the spindle guide is disposed in a spindle guide housing, and that this spindle guide housing is placed in a sliding guide so that it can be displaced parallel to the guide columns and can be fixed with respect to the cutter holder at different vertical distances by means of a clamping device.
