Inclining and rotating table apparatus

An inclining and rotating table apparatus comprising:

• a base;
• a rotary table device supported by said base, the rotary table device having
• a driven rotating shaft driven to rotate by a first drive source,
• a rotary table, and
• a rotating turret that is connected to said rotary table and is rotated by said driven rotating shaft;
• and
• an oscillating turret;
• a driven turning shaft on said base for causing inclination of a table surface of said rotary table device by causing said oscillating turret to turn, said driven turning shaft being driven to turn by a second drive source;
• and
• a clamping device for clamping at least one of said driven rotating shaft and said driven turning shaft;
• wherein said clamping device has a thin-walled sleeve arranged such that a gap is provided along a circumferential direction of at least one of said driven rotating shaft and said driven turning shaft;
• said clamping device clamps said at least one of said driven rotating shaft and said driven turning shaft by deforming said thin-walled sleeve towards said at least one of said driven rotating shaft and said driven turning shaft;
• said gap includes an oil;
• and
• a surface of said at least one of said driven rotating shaft and said driven turning shaft is provided with a groove into which said oil flows when said clamping device clamps said at least one of said driven rotating shaft and said driven turning shaft by deforming said thin-walled sleeve towards said at least one of said driven rotating shaft and said driven turning shaft.
