ABSTRACT:
The invention relates to a device (10) for cutting a workpiece (38), mounted onto an elongate rod (36), into a spiral formation. The device includes a frame (12) defining a workspace (14), and a locating mechanism (34) for locating the rod longitudinally along the workspace. A chuck (40), rotatable about an axis of rotation, is located in the workspace for holding and rotating the work piece about an axis co-axial with the axis of the rod. A carriage (44) which is transportable longitudinally along the workspace releasably mounts a cutting tool (46) extending transversely to the workspace. The device includes also a transport mechanism (48) for transporting the carriage longitudinally along the workspace and a displacement mechanism (34) for displacing the locating mechanism, and hence in use the rod, longitudinally along the workspace. The device further includes a drive mechanism (52) for driving the transport mechanism, the displacement mechanism and rotatingly driving the chuck.
