Abstract: The invention is directed to a machine tool for edge machining a workpiece. The machine tool includes a drive unit for a rotary tool, a guide device for guiding the workpiece in a horizontal infeed direction and a chip collecting hood. The guide device includes an upper pressure element and a lower pressure element and one of the pressure elements is settable in the vertical direction relative to the other pressure element and also the drive unit. The chip collecting hood includes a side wall having a cutout for receiving an edge region to be machined of the workpiece. The side wall includes a base wall part and a closure wall part. The base wall part is positioned fixedly relative to the drive unit and the closure wall part is positioned fixedly relative to the pressure element to be settable in the vertical direction. The closure wall part delimits the cutout in the vertical direction.

Abstract: A milling tool has a support member with an exterior surface with at least one receptacle, wherein the at least one receptacle has a bottom. At least one cutting element provided with a cutter having a cutting edge is positioned in the at least one receptacle. A three-point support is arranged between the at least one cutting element and the bottom of the at least one receptacle for positioning the cutting edge relative to the bottom of the at least one receptacle. The three-point support comprises three support pads arranged at a bottom side of the at least one cutting element and/or three projections arranged at the bottom of the at least one receptacle.

Abstract: The invention relates to a treatment unit with a cutting tool (1) for treating wood, plastic or the like. Said treatment unit comprises a suction hood (6) with a ring (17) that encircles the tool (1) completely in the circumferential direction and at least partially in the axial direction. The suction hood (6) is located on the side of the drive spindle of the tool (1). A chip receiving opening (10) is provided in the tool (1) in the vicinity of the blade (4), said opening traversing the tool (1) in both the axial and the radial direction. A chip formed at the blade (4) is transported through the chip receiving opening (10) to the suction hood (6) from where the chip is removed by air suction.
