Vorrichtung zum Bearbeiten von langen Werkstuecken

The device for machining long workpieces (10) using high energy radiation has a head (12) that is adjustable relative to the outer radius of the workpiece. The position of the head is adjusted by a ring (16) which surrounds the workpiece. The centreline (14) of the head coincides with the axis(15) of the workpiece. The ring is supported in bearings on its outer periphery within an intermediate ring (18) which itself is supported by bearings in an outer ring (19). The outer ring is fixed or can move parallel to the workpiece. The inner and intermediate rings are coupled to a control drive(20). The head has a radially and/or axially sliding auxiliary axis. ADVANTAGE - The periphery of the workpiece can be machined without having to rotate it
