Abstract: A machine tool (1) for the at least partial machining, contour-dependent cutting or milling of a component from a plate-shaped workpiece (2), for example a wood plate, is provided, and includes a suction device used as a clamping device for engaging on the back side or lower side of the workpiece (2). A second clamping device including at least one hold-down device (6) that is used to apply pressure to the side of the workpiece (2) facing away from the suction device (3) and (4) is provided. The hold-down device (6) has on its contact region that applies pressure to the workpiece (2) at least one or two spaced-apart pressure rollers (7), and is displaceable under pressure relative to the workpiece (2) transversely to the axis of the pressure roller(s) (7). The displacement is synchronous with a tool (8) used for the machining of workpiece (2), which tool can preferably be situated between the two spaced-apart pressure rollers (7).

Abstract: An apparatus for planing opposite sides of a workpiece has a housing having a lower part and an upper part flanking a passage through which the workpiece to be planed is passed horizontally in a travel direction. Respective upper and lower planing drums rotatable on the respective housing parts above and below the passage about respective upper and lower axes extend transverse to the direction and define on rotation respective upper and lower cutting orbits centered on the respective axes. The lower drum is upstream of the upper drum relative to the workpiece travel direction. A stationary workpiece support table between the drums has an upper surface level and tangent with the lower orbit. Thus the underside of a workpiece passed in the direction over the lower drum is planed and slides downstream of the lower drum on the table surface.
