A multi-operation machine (1) comprises a machine frame (2), a holder (3), which is arranged to hold a workpiece (4) and to move said workpiece during machining thereof along three axes constituting a first (x), a second (y) and a third (z) axis of a three-dimensional co-ordinate system, and at least two tools (5), which are each fitted to a support (6) adn which are arranged to machine the workpiece (4) in sequence while this is being displaced by means of the holder (3). Each support (6) is arranged to assume a fixed position relative to the machine frame (2) while the workpiece (4) is being machined by the associated tool (5). The machine frame (2) has the shape of an upwardly open U-shaped channel (7) over which the support (3) extends like an overhead crane and which has a bottom portion (10) in which the supports (6) are arranged. |
