The guide apparatus in accordance with the invention for the guiding of a workpiece ( ), in particular of a rotationally asymmetrical workpiece ( ), having a porous surface coating ( ) in a polishing container ( ) has two guide members ( ) spaced apart by at least one spacer ( ) as well as a holder ( ) for the positioning of the workpiece ( ) between the two guide members ( ) such that the workpiece ( ) can be guided in the polishing container ( ) in a non-contact manner with respect to the polishing container ( ).

Guide apparatus for a workpiece having a porous surface coating and a method for the polishing of such a workpiece

Starting on the surface of a foundation body (2) weld material is applied in runs to form layers by an equipment for profiling building-up welding and hence a workpiece (1) is manufactured, where the foundation body (2) may be a component of the workpiece (1). The course of runs to form layers as well as the approximate rate of application of weld material are calculated by a computer system (11), starting from a two- or three-dimensional data model of the workpiece (1) in the form of software, and given over to the system control (10) which positions the welding torch (7) by means of the robot (5) and the workpiece (1) located on a turntable (4) by a clamping mechanism (3) with respect to one another, and regulates the rate of application of weld material applied by the welding apparatus (8) in such a way that the liquid weld material adheres to the layer lying underneath without running down and irregularities in the runs to form layers are levelled out. Hence metal workpieces having manifold bodily shapes and theoretically of any size and having any thickness of wall, even consisting of different metallic materials, may be manufactured by profiling building-up welding without auxiliary cores or other devices supporting the liquid weld material.
