Machine tool

A machine tool having a work moving in a Z axis direction on a stationary body section and a rotary spindle for machining the work, comprising:

• a pair of guide tracks extending in the Z axis direction away from an X axis direction intersecting the Z axis direction on the stationary body section;
• a pair of feed tables guided by said guide tracks and movable independently;
• a support/feed/turn output member for supporting the work, the support/feed/turn output member being arranged between said feed tables so as to bridge said feed tables, the support/feed/turn output member being coupled with one of said feed tables to be relatively rotatable around a line in a Y axis direction which intersects both the X axis direction and the Z axis direction perpendicularly, and the support/feed/turn output member being coupled with the other of said feed tables to be relatively rotatable around the line in the Y axis direction and to be movable in a specific direction related to the positions of the feed tables;
• and
• a control box controlling the rotary spindle machining by changing a facing angle of the work relative to the rotary spindle by feeding the feed tables on the guide tracks so as to change the positions of the feed tables relative to one another, thereafter feeding the feed tables on the guide tracks a line in the Z axis direction in a state in which the changed relative positions are maintained.
