Appts. for cutting and chamfering large tubes - giving high precision, for use prior to welding

摘要

Each machine comprises a frame moved on rollers on the rails of a bench, an oscillating assembly rotating about the axis of the tube to be cut and formed from a pair of discs rotating between rollers of the frame; a sliding arm controlled by a screw resting on the discs and a nut fixed to the arm presenting a groove and slider, the latter supporting the oscillating head of the inclinable torch support; and an arrangement for controlling the movement of the torch. Precise cutting of the tube is achieved.
