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.
A process for longitudinal adjustment of tools each in one of a plurality of individual working spindles of a multiple-spindle automatically controlled machine tool, from a respective working-part reference point established through respective measuring devices as a zero-point coordinate of a common processing program;
A process for longitudinal adjustment of each of a plurality of tools of a machine tool in which working spindles each individual to a respective one of the tools are arranged together at a slide moveable along an axis of the machine and in which the working spindles individually have spindle sleeves adjustable in axial direction;
A process for longitudinal adjustment of each of a plurality of tools of a machine tool in which working spindles each individual to a respective one of the tools are fixed to a swinging basket which is swingable around an axis passing vertically through all spindle axes and at which working spindles are swingable in all cases perpendicularly to shafts standing on said axis, whereby the working spindles have spindle sleeves moveable in the direction of their shafts;
A process for longitudinal adjustment of individual tools in their working spindles in a multiple-spindle automatically controlled tool machine to a respective working part reference point as a zero-point coordinate of a common processing program, whereby the working spindles are parallel with and are controlled relative to a common axis in their respective axial movements toward the zero-point coordinate by means of a process characterized in that the working spindles are commonly adjusted in the direction of the common axis to a pre-position with respect to the working part reference point, then the tools set into the working spindles are adjusted individually in the direction of the individual lengths in a respective axis parallel with the common axis and are run in rapid advance against a respective measuring device producing a first signal upon the respective tool reaching a predetermined distance from the working part reference point, said first signal stopping the individual rapid advances of the other working spindles, whereby the first signal from the measuring device last reached by the tool involved switches on crawling speeds for all of the working spindles and wherein each of the measuring devices produces a second signal on reaching the working part reference point zero-point coordinate by the tool involved, whereby the working spindles are stopped individually by said second signals and the starting point for all working spindles thereby is obtained for the common processing program.
