ABSTRACT:
A beam-catching device is provided for a cutting-beam processing machine configured to deliver a cutting beam to a workpiece. The beam-catching device includes a housing which has a line-like opening pointing toward the cutting beam, the cutting beam discharging from the underside of the workpiece during processing of the workpiece and entering the housing through the opening, and a solid medium disposed within the housing and configured to move relative to the opening of the housing in a direction crossing the cutting beam in order to absorb energy.
