ABSTRACT:
Elongate round workpieces W (e.g. bar or tube) are loaded singly from a rack (252) on to a supporting cradle formed by four ball castors (38). At each end of the cradle is an upper operating unit (20) and (22) comprising a machining unit having a chamfering tool (34) and a workpiece-driving unit having a driving wheel (32) in frictional engagement with the workpiece. The wheels (32) are rotated about their axes to rotate the workpiece, and further can be pivoted to each side of a neutral position in order to drive the workpiece along its length into engagement with first one chamfering tool and then the other. The operating units are mounted on upper guide rails (16) and (18) for adjustment of the distance between them. Lower operating units mounted on lower guide rails (24) and (26) comprise deburring tools (36) which also operate on the workpiece ends, adjacent to the chamfering tools (34).
