A burning table including numerous upright copper support cylinders carried on a load-bearing steel grid to form a horizontal work surface. A high water level provides rapid cooling of the cylinders as the burning tool moves along the surface supported workpiece and eliminates pollution by quickly disintegrating slag. Individual cylinders are reversible in the grid for extended life, and damaged cylinders are easy and inexpensive to replace. The support cylinders are crowded on the grid for complete support of even relatively small parts. A hopper-shaped pan collects slag, and a vibrator causes the slag to move into a collection bin for quick and convenient removal.
