Werkzeugmaschine mit einem Drehtisch

摘要

The workpiece holder (10) rotates above a fixed support frame (13) about a central axis (15) through a central duct (18) through the holder and support. Fluid supply lines (21,22) are located through the duct and terminate in connections through a plate (23) fitted top the top of the duct. The supply lines hang down through the duct and permit a certain amount of rotation of the workpiece holder. At least one (21) of the supply lines is positioned central to the holder while the other connections are arranged around the central axis. The supply lines can include rotational couplings (31).
