<p>The finding concerns a machine tool for chip removal, of the type which comprises a work centre (100), made up of a plurality of operating units, comprising a spindle, a piece-carrying table, a tool store and at least four spindles (M1.1, M2.1, M1.2, M2.2) fed by the corresponding tool stores (T1.1, T2.1, T1.2, T2.2) and where the pieces (P) to be worked are mounted on a piece-carrying trolley (1) able to slide horizontally in the direction (Y) to position the pieces (P), alternatively, at the spindles (M1.1-M2.1) applied on a first work station (S1) and at the spindles (M1.2-M2.2) applied onto a second work station (S2), in order to allow said pieces (P) to be positioned at the spindles being worked, whereas the other spindles, at the same time, are engaged in the tool-change operation and vice-versa, characterised in that the piece-carrying trolley (1) orients the pieces (P) in three-dimensional space so as to present them to the corresponding spindles at infinite positions ( Fig. 1 ).</p> |
