    摘要： The invention relates to an automatic machine tool (10), for the production of base structures (68), for false teeth, in particular, for tooth crowns and/or tooth bridges of exact three-dimensional shape. Said base structures (68) may be fixed to prepared natural and/or artificial tooth stumps. The machine tool (10) comprises a machine frame (12, 14), or a body, a work piece carrier, with a rotation shaft (38), at least one digitisation unit (46), at least one machining unit (52) and an electronic arithmetic and control unit (50) for all drive lines. A carrier for the workpiece, a blank (42), and/or for the machining unit(s) (52), serves as displacement unit, with three translational axes in the x-, y- and z-directions. The digitisation of the preparation model (44) and the machining of the blank (41) are carried out on the same machine tool (10), at different times. The machining paths for the blank (42) are calculated from the measured and stored digitised data and a predetermined material-specific scaling factor, before the machining of the blank.

    摘要： A coping device includes a circular blade (12), a template having an end provided with a coped profile, a stylus (15) which traces the coped profile of the template and which preferably has substantially the same width and radius of curvature as the circular blade, clamps (132, 134, 140, 142) for respectively securing the molding and the template in a fixed position, and a base (20) having a stationary portion (22) and a movable portion (24) movable in X and Y directions relative to the stationary portion (22). The clamps (132, 134, 140, 142) are coupled to the stationary portion (22), and the blade (12) and stylus (15) are both coupled to the movable portion (24). The blade (12) and stylus (15) are substantially simultaneously movable relative to the clamps (132, 134, 140, 142) so that the molding can be coped with the circular blade as the stylus (15) traverses the coped profile of the template.

    摘要： During the production of staff panels, it is a known measure to use a belt sanding machine to smooth panels whose surfaces have been roughened by treatment. The sanding belts become worn down and accumulate grinding dust and so must be replaced frequently. With the novel device, accumulation of dust on the tools is prevented and wear minimised. A rotating worm (7) with drive is provided above a conveyer belt (1). The device is incorporated in a staff panels production facility preferably upstream of the dryer. The panels are smoothed when still damp and thus without any dust being produced. The novel device is also suitable for smoothing panels or battens made from other materials such as wood or plastic. Also included in the invention is a hand device of design analogous to that of the fixed device and based on the same principle.
