Multifunction modular machine tool for integrated machining processes

A multifunction modular machine tool for integrated machining processes, comprising a main headstock (30) suitable for holding a workpiece to be machined (P), in such a way as to dispose it inside a workspace (A) and to carry out a rotation (CC1) of the workpiece (P) about a main axis (ZZ1) during different machining operations, a first work guide (41) which supports a turning or multi-tool unit (10) and at least one further work guide (42), said work guides (41, 42) extending in a direction substantially parallel to said main axis (ZZ1),

• comprising a tool for machining processes of screw milling and/or bevel gear cutting (210) and a tool for machining processes of spur gear cutting (220) which are associated with at least one further work unit (21, 22, 22′) movable on said further work guide (42), said tool for machining processes of screw milling (210) and said tool for machining processes of gear cutting (220) being movable on said further work guide (42) by translational and/or rotational movements, in such a way as to be able to be disposed, alternately and independently of one another, inside said workspace (A), in order to operate on the workpiece to be machined (P), or outside said workspace (A).
