Abstract:
1. A machine tool for the synchronous machining of workpieces, said tool being comprised of: at least two spindle units, which run parallel in a machining unit for reception of tools; and repositioning devices for precise adjustment of the position of the spindle units in relation to one another in all three directions x, y, and z of the orthogonal co-ordinate system in the machining unit, wherein the repositioning devices for displacing at least one of the spindle units in at least one of the directions x and/or y each comprise an eccentric bush, which can be rotated about a central axis of the respective bush and locked and in which the rotary tool axes of each of the spindle units are mounted eccentrically relative to the central axis of the respective bush, parallel to said central axes; and wherein each eccentric bush is rotated by a linear movement of a respective piston.
