<p>Workpiece (1) speed is sufficient to remove melt (13) from the melt zone (12) by centrifugal force. It is flung away tangentially from the workpiece. The beam source (8) and/or a processing spot are arranged to rotate about a second axis. The first axis of rotation (R1) coincides with the second. Beam source and processing spot are moved with respect to the workpiece first rotational axis, in one or more of the following directions: parallel, radially, transversely and/or circumferentially. Each processing operation is repeated many times. To assist melt removal, a gas expels it. An independent claim IS INCLUDED FOR the corresponding processing method.</p> |
