An apparatus for providing a vacuum coating to workpieces positioned on a rake unit, including: a substantially rectangular central chamber; a first chamber located adjacent the central chamber on a first side, wherein the rake unit is positioned in the first chamber after workpieces are loaded thereon; a second chamber located adjacent the central chamber on a second side, wherein workpieces on the rake unit are heated to a predetermined temperature; a third chamber located adjacent the central chamber on a third side, wherein workpieces on the rake unit are coated in a desired manner; a fourth chamber located adjacent the central chamber on a fourth side, wherein workpieces on the rake unit are unloaded; and, a mechanism for transporting the rake unit from the first chamber to each of the second, third and fourth chambers in a desired sequence via the central chamber. The transporting mechanism further includes: a manipulator arm configured to grab the rake unit, the manipulator arm being movable so that the rake unit is pulled into and pushed out of the central chamber; and, a turntable associated with the manipulator arm, wherein an orientation of the rake unit with respect to the central chamber is controlled by rotation thereof
