ABSTRACT:
On the tool spindle of a machine tool, a hollow ring is mounted on the headstock or on the sleeve flange thereof and is provided on its underside with an annular clearance forming an endless ring nozzle. A pressurized fluid is introduced into the channel of the hollow ring and passes out of the annular clearance in the form of a closed fluid curtain, so that a closed space surrounding the machining station is formed. So as to obtain a permanent seal with the fluid curtain, an annular element comprising a deflecting ring, a filter ring and a straightening ring is built into the annular channel and as a result the latter is subdivided into an upper and a lower partial ring channel. The suspended dust formed during the machining of a workpiece is held back by the fluid curtain, but the machining point is still visible and unimpeded access is possible.
