Abstract: In a machine tool, in particular a laser machine tool, a workpiece slide or tool slide is movable along a guide rail and has at least two guide carriages that are guided on the guide rail. The machine tool has a covering hood that is moved along with the slide, for covering that rail section of the guide rail that is located between the two guide carriages. The covering hood is a part that is not connected to the slide. The covering hood is guided on the guide rail in a displaceable manner between the two guide carriages and is entrained in the displacement direction by the rear guide carriage when the slide is displaced.

Abstract: A laser machining system includes a workpiece support, a laser machining unit arranged above the workpiece support and for machining a workpiece located on the workpiece support, at least one extraction opening beneath the workpiece support, and an enclosure separating the workpiece support, the laser machining unit and the at least one extraction opening from an external environment. The enclosure includes at least one air inflow opening arranged above the workpiece support and relative to the at least one extraction opening such that, during operation of the laser machining system, a pressure difference between the air inflow opening and the at least one extraction opening establishes a flow of air between the workpiece support and the laser machining unit, in which the flow of air separates the interior of the enclosure into a laser machining area beneath the flow band and a laser free area above the flow band.
