ABSTRACT:
Disclosed is a dust collecting apparatus (10) that is attachable to a machine tool (12) to remove dust created during the tool's operation. The dust collection apparatus includes a cylindrical sleeve (24) mounted on the body (14) of the machine tool and extending outwardly over the spindle (16) of the tool to a point near the tool's cutter (20). A cylindrical shroud (34) is fastened to and surrounds the sleeve (24) and creates a chamber (44) between the sleeve and the shroud. Duct tubes (48) attached to the shroud connect the chamber and a vacuum source. The applied vacuum creates suction in the chamber which has its inlet end (46) located near the cutter of the machine tool. A restrictor ring (50) attached to sleeve (24) at the inlet end of the chamber minimizes the cross-sectional area of that portion of the chamber to create a high velocity airstream very near to the point at which the dust particles are produced. The airstream deflects the dust particles into the chamber. The dust particles leave the chamber via the duct tubes (48).
