THERMAL CUTTING APPARATUS |
摘要 |
To cut paper, timber, fabric etc., with a laser beam, a jet of air (or other gas which is inert in the process) carrying an atomized stream of a liquid coolant is directed on to the moving region of the workpiece at which the laser beam is concentrated. This reduces the spread of charring or tar deposit from the cut along the surfaces of the workpiece.
