System zur Absaugung von Spänen und/oder Staub für den Kopf einer Fräsmaschine mit automatischem Werkstückwechsel

摘要

The system has a rotating spindle (1) comprising a central hollow tie rod (5`) extended axially for the passage of lubricant. A tool support (2), an attachment cone (3`) and a clamping jaw (4) are assembled at an end of the spindle. A fixed suction pipe is connected to a posterior part of the tie rod, and a rotating expansion joint (8) permits rotating movement of the tie rod while the pipe remains static. The suction pipe permits extraction of chips and dusts through the interior of the tie rod.
