A machine tool has a rotary element 1 with slides 16, 16', which may carry cutting chisels 2, 2' or chuck jaws (21, Figure 2). Rotary element 1 can be driven to rotate about a spindle axis 17, and slides 16, 16 can additionally be moved radially with respect to spindle axis 17. The radial movement is introduced into the rotary element by an epicyclic gear 19 through a shaft 14 arranged concentrically with respect to spindle axis 17. The epicyclic gear may be preassembled to or retrofittable to rotary element 1. Advantageously, slides 16, 16â may move synchronously to avoid imbalance.
