Abstract

The invention comprises a tool turret for a turning machine whose operational axis has a wider spacing from the bed of the carriage than the spindle axis of the turning machine. The tool turret has an inner rim with inner turning tools and an outer rim with outer turning tools, the inner and outer turning tools being angularly offset in relation to each other. In order to bring the inner and outer turning tools into operating position during the stepwise further movement of the turret, successive operational angles must be variable. Because of the wider spacing of the operational axis from the bed of the carriage, the turret disc carrying the tools can be made larger with the result that more tools can be provided thereon or the spacing between the tools can be enlarged. The changeover with unequal angles can be accomplished by means of a regulated direct current motor, the operational angle being fed into the regulation circuit as the desired value.

Dependent claims

A turret for processing tools on a turning machine, which is disposed on a cross-slide rest displaceable vertically to a spindle axis of the turning machine on a turning carriage, the latter in turn being displaceable parallel to said spindle axis, comprising:

a first set of inner turning tools forming processing tools disposed at equidistant spacings on a circle around an operational axis of the turret, extending parallel or substantially parallel to the spindle axis;
a second set of processing tools, at least one of which is an outer turning tool, disposed with their cutting tips outside the circle of said first set so that a tool of one set is always disposed between two tools of the other set, the distances of the cutting tip of one outer turning tool and the two adjacent inner turning tools of the first set being equal or substantially equal to the distance of the tips of the two adjacent inner turning tools, the cutting tip of the tool which at a given time is in its operational position being in a plane extending substantially parallel to the bed of said carriage;
means for supporting said turret so that its said operational axis is at a greater distance from said carriage than said spindle axis;
and means on said turret for shifting it about its operational axis at unequal angles.
