High-performance facing head

A facing head (1) comprising:

• a fixed part (4) couplable with a head of a machine tool (2) via an interface plate (3);
• and
• a rotary part (5) which supports a radial slide (6),
• wherein a compartment (35) is obtained in said rotary part (5), said compartment (35) containing drive means (100) and measurement means (101) for driving and measuring said radial slide (6), wherein said radial slide (6) is supported by said rotary part (5) so as to close the compartment (35), and wherein at least one electric collector (20) is located in said compartment (35), said least one electric collector (20) being configured for transmitting the electrical signals for controlling said drive means (100) and measurement means (101) used for driving and measuring said radial slide (6),
• said facing head (1) being characterized in that it comprises:
• a continuous gasket (40) configured in such a way as to completely make contact with the radial slide (6), said gasket (40) being housed inside a respective recess (34) which externally surrounds the compartment (35);
• and
• a fluid collector suitable for supplying said compartment (35) with pressurized air, so that the pressure inside the compartment (35) is higher than the atmospheric pressure, in order to seal the compartment (35), wherein said fluid collector comprises a rotary portion (22), which is integral with said rotary part (5) of the facing head (1) and comprises internally thereto first fluid routes (43), and a fixed portion (23), which is integral with said fixed part (4) of the facing head (1) and comprises internally thereto second fixed fluid routes (45) coupled with said first fluid routes (43) to supply said rotary part (5) with a coolant, to supply said compartment (35) with said pressurized air, and to transport oil used to implement automatic locking of the radial slide (6).
