ABSTRACT:
A system is described for coating a cylindrical surface of a long thin workpiece by a process which includes flame spray coating that heats the workpiece to a large portion of its melting temperature and which is followed by grinding of the coated cylindrical surface, which produces a final coated surface of more uniform coating thickness than heretofore. The workpiece is rotated about a vertical axis, to avoid slight bending deformation of it, the upper end of the workpiece is allowed to move slightly towards and away from its opposite end, and an upward bias is applied to the chuck device that engages the upper end of the rotating workpiece to avoid column-like buckling of it.
