| 摘要 |
<p>The invention relates to a shielding device (8) shielding a machining beam (19) emanating on a machining head (6) of a machine tool (1) and/or a machining site (20) of the machining beam (19) from the environment. Said shielding device comprises at least two shielding units (13) having shielding elements (18), which are fastened to element holders (16). The element holders (16) of the shielding units (13) can be moved, together with associated shielding elements (18), relative to one another, in order to shield the machining beam (19) and/or in order to shield the machining site (20) of the machining beam (19). A machining head (6) of a machine tool is provided with a shielding device (8) of the type described above. A machine tool comprises such a machining head (6).</p> |
