The invention relates to a machine for multi-tool performing centering and spherical turning operations. According to the invention, the machine comprises a bed frame (B) provided with some longitudinal guides on which there is mounted a head stock (1) having a main axle and a central cardan shaft (2) transmitting a rotation motion to some cardan axles (24) driving some combined tools (4) sustained by some tool-holder axle carriers (3) adjustable from an adjustable multi-spindle head (23) placed, fixed and stiffened by a support (12), some elbows (11) and a base plate (15), as well as by some connecting bars (14), while, in the opposite part, on the longitudinal guides there is placed a driving device (8) transmitting the motion from an electric motor (22) to a multi-spindle head (7) adjustable by means of eccentrics, sustained by a support (13), on a transverse guide of a carriage (26) there being positioned and fixed a rotary device (16) which, at its top part has two working points in positions I and II, placed on a base plate (10) with some blanks oriented in some fixed prisms (5) and clamped by the control of a distributor (19) which moves a piston of a pneumatic motor (18), a bilateral key (21) and some levers (6). |
