ABSTRACT:
The present invention relates to an apparatus for coating one or more workpieces such as components to be used in jet engines or industrial turbines. The apparatus comprises a device for simultaneously manipulating a workpiece about multiple axes while holding a center of the workpiece at a fixed position with respect to a source of coating material. The device for manipulating the workpiece preferably comprises a modular fixture while allows the workpiece to be simultaneously rotated about a first axis, rotated about a second axis at an angle to the first axis, and titled through a range of motion such as from +45 degrees to −45 degrees with respect to the first axis.
