RETRACTABLE PROTECTIVE PANES

Disclosed is a cutting machine, having a table with a working surface designed to receive an object to be cut, a light curtain device and a protective pane. A crossbeam is arranged above tho working surface, designed for linear positioning parallel to a first horizontal axis. A module is mounted on the crossbeam and provides for linear positioning, parallel to a second horizontal axis. The second horizontal axis extends at right angles to the first horizontal axis. In a first operating state, the protective pane on one side of the table is below the working surface plane. In a second operating state, both the protective patio and a light curtain generated by the light curtain device, on the side of the table are at least partially above the working surface. In the second operating state the light curtain is located at least partially above the protective pane.
