It is described a direct drive two rotary axis spindle head (1) comprising a fork (5), rotatable around a first axis (B), with two arms (3, 4) accommodating between them an electric spindle (2). The electric spindle (2) is rotatable around a second axis (A) perpendicular to said first axis (B). A first direct drive electric motor (6) for the rotation of the fork (5) around said first axis (B), and at least a second direct drive electric motor (9) for the rotation of the electric spindle (2) around said second axis (A). The second motor (9) comprises a rotor (10) and a stator (11), where the stator (11) is housed in a casing (12) fixed to the outer faces (13, 14) of the fork (5), in such a way that the casing (12) and part of the rotor (10) remain on the outside of the fork (5). |
