The invention relates to a treatment unit with a cutting tool ( ) for treating wood, plastic or the like. Said treatment unit comprises a suction hood ( ) with a ring ( ) that encircles the tool ( ) completely in the circumferential direction and at least partially in the axial direction. The suction hood ( ) is located on the side of the drive spindle of the tool ( ). A chip receiving opening ( ) is provided in the tool ( ) in the vicinity of the blade ( ), said opening traversing the tool ( ) in both the axial and the radial direction. A chip formed at the blade ( ) is transported through the chip receiving opening ( ) to the suction hood ( ) from where the chip is removed by air suction.

Machining assembly including a rotating tool and exhaust hood

The invention relative to a device for machining workpieces comprising: a chip removing, rotating tool ( ) configured substantially as a hollow body including at least one cutter ( ), a portion of the tool adjoining the cutter ( ) being penetrated by a chip receiving opening ( ) for communicating chips into a tool cavity; and an exhaust means including a stationary exhaust housing ( ) configured substantially as a hollow body communicating with the cavity ( ) at least in part and in connection with at least one exhaust air source; the communicating portion of the exhaust housing ( ) comprising in the region of the cutter ( ) a chip communicating window ( ) porting into an exhaust passage ( ) of the exhaust housing ( ); and the exhaust passage comprising in an exhaust passage section upstream of the chip communicating window ( ), relative to the exhaust direction, at least one auxiliary air infeed opening. The invention relates furthermore to a method for machining workpieces by means of one such device.
