The present invention relates to a laser processing machine. A table supports a workpiece to be processed at a work area. A processing head assembly is arranged above the table. A nozzle is connected at a lower end of the processing head assembly and applies a laser beam to the workpiece together with an assisting gas at the work area. A device is provided at the work area for supplying air to keep the workpiece to be processed afloat while the laser beam is being applied to the workpiece together with the assisting gas. A similar device is provided at the lower end of the processing head assembly for supplying air to keep the workpiece to be processed from going up into contact with the processing head assembly while the laser beam is being applied to the workpiece together with the assisting gas. These devices for supplying air include a plurality of air chambers. |
