Abstract
A cutting table assembly for oxy cutting comprising a cutting table having a slab loading face and mounted for pivotal movement between a loading position in which the loading face is generally horizontal and a cutting position in which the face is oblique, and a pair of torches mounted on the table. The loading face is constituted by a pair of loading subfaces separated by a slot and the torches are mounted in the slot below the loading face. The torches are positioned at opposite ends of the slot prior to the initiation of the cutting action and, upon the initiation of the cutting action, move toward each other and cut into opposite ends of the slab. A pair of gantries are mounted on the table and each carries a deburring device positioned in overlying opposition to a respective torch. Each gantry further includes a plurality of spaced downwardly directed nozzles which are supplied with compressed air to generate an air curtain.
