<p>The invention relates to a digitally controlled milling head with two rotation axes, for complex processing operations by cutting-out. According to the invention, the head has a module (A) for rotation around the longitudinal axis (a-a), actuated by an electrical engine (30) with variable speed, through a linkage, consisting of a planetary reductor (31), with a reduced angular clearance, a reductor (32) with a conical group, which transmits the movement to a toothed belt pulley (35) integral with a hollow pivot (15), the latter being integral with a housing (4) rotating around the longitudinal axis (a-a), the control of the feed circular movement being provided by a transducer (41) kinematically connected, through a gear without clearance, consisting of a toothed crown (42) and a toothed wheel (43), mounted on an axle (44) coaxial to the transducer (41) and supported in a housing (45) by an eccentric boss (f).</p> |
