The present disclosure teaches a process and related apparatus for longitudinal adjustment of tools for individual working spindles of a multiple-spindle automatically controlled machine tool. The tools introduced into the working spindles in the direction of their lengths to be adjusted are run in rapid advance in all cases against a measuring device which, on reaching a predetermined distance from the working part reference point, produces a first signal in which the rapid advances of the working spindles are switched off individually. The first signal from the measuring device finally reached by the tool involved switches on crawling speeds for all working spindles. The spindles are switched off individually on reaching the working-part reference points in all cases by a second signal from the measuring devices. |
