Abstract: An automatic transfer machine having a plurality of machining units on a common table top with tool carriers above and a common drive below the table top connected through openings in the table top by distributor gears connecting the common drive with intermediate shafts, which shafts are arranged at approximately at right angles relative to the plane of the table top. Universal joint shafts which are telescopically extensible extend through each of the table top openings connecting intermediate shafts from below the table top to step down gears and control elements above the table top.

Abstract: A machining unit with a working spindle supported in a spindle housing and a saddle on which the spindle housing is removably secured and which is guided on a saddle carrier for sliding movement axially of the working spindle to cause the working spindle to be moved by feed motions, and with a drive motor secured to the saddle carrier and a transmission driven by the drive motor, the transmission having a hollow shaft in which the working spindle is guided for axial sliding movement and for rotation by the hollow shaft supported in a holder adjustable and lockable relative to the saddle carrier in two directions perpendicular to the axial direction of the working spindle.
