One of our fab shops at work has a Vulcan PC. The cutter is controlled by a computer, and there are two sections of table that take full pieces of sheet steel. The cutter travels between the two tables so the operator can remove cut pieces and reload the one while the cutter burns out shapes on the other. The tables on it look like the steel grating used on catwalks. They cut an awful amount of sheet metal on it, and I think the grate is at least 10 years old................chim
