The miller comprises a pair of benches situated on both sides of a framework, in such a manner that on the upper crossbar is mounted, displaceable and guidable, a transverse support that carries a couple of vertical arms on which are mounted the corresponding tools, the arms being dispaceable towards one side or the other with respect to the support, while the tool that is borne by each of the arms may move upward/downward, as well as rotate, in such a manner that a combination of these movements produced by their corresponding motors allows simultaniously making two pieces that are symmetrical or the same, as well as effect simultanious digitalized work with one arm and milling with the other, after having mounted the corresponding tool on one arm and a digitalizer on the other.

A surface of a workpiece, from which the burr is removed, is traced when a machining tool is pressed onto the surface of the workpiece under force control so as to find the positional data of the surface shape (S1). This positional data is corrected by an error caused by a bend of a robot (S2). The thus obtained positional data is compared with the target shape of the surface, from which the burr is removed, obtained from CAD data (S6, S10). A shift of the surface shape in the normal line direction is found (S7, S11). The burr generation start position, the burr generation end position and the height of the burr are found by the shift start position (S8), the shift end position and the shift size (S14). A machining program is made which is composed of a pass connecting the burr end position with the burr start position and also composed of a cutting pass for removing the burr, and the thus made machining program is executed (S16, S17). As the burr position is found and the burr is removed when the machining tool is moved to the burr position, the burr can be effectively removed. Due to the foregoing, it is possible to provide a finishing machine characterized in that useless burr removing actions can be reduced and, further, that the overcutting of a workpiece can be prevented.

The invention relates to an electric tool comprising a housing, which accommodates a drive. Said electric tool contains a shaft, in which a chuck (20) is located for receiving a tool attachment (19). The chuck (20) is surrounded by an annular bearing surface (9). The bearing surface (8, 9) comprises mounting elements and mounts (21, 22; 31, 32) and (33) for interchangeable tool attachments (25), e.g. jigs that can be mounted onto the bearing surface (8, 9), said mounts allowing the electric tool to be guided on a guide rail (1, 35).

Es wird ein X-Y-Koordinatenwagen für eine in der Holzbearbeitung einsetzbare Oberfräse angegeben, mit dem eine solche nachträglich ausrüstbar ist. Der Längswagen umfaßt einen in Leichtbauweise erstellten verwindungs- und biegesteifen Rahmen, der mit im Abstand voneinander angeordneten Lagern an einer seitlich an dem Maschinentisch der Oberfräse festlegbaren Führungswelle verschiebbar geführt und an der gegenüberliegenden Seite des Maschinentisches mit einer Stützrolle an einem seitlich an diesem parallel zur Führungswelle verlaufend befestigten Stützstab abgestützt ist. Zur Abstützung und Führung des Querwagens vorgesehene Führungswellen und Halteblöcke für diese sowie Lagerblöcke für die verschiebbare Lagerung des Querwagens sind in den zwischen Hohlprofilträgem des Längswagens und des Querwagens verbleibenden Zwischenräumen angeordnet, wobei die Führungswellen etwa in Höhe der horizontalen Längsmittelebene derHohlprofilträgerdes Längswagens verlaufen. Lagerschalen von Gleitlagem, mit denen der Längswagen an der Längsfhürungswelle und der Querwagen an dem Längswagen verschiebbar gelagert ist, sind in Bohrungen von Lagerblöcken eingegossen, deren lichter Durchmesser größer ist als der Außendurchmesser der Lagerschalen.

The invention relates to a method for profiling a running surface (4) of a laid rail (2) by means of a processing vehicle (34), in particular in the region of a switch (10), comprising touching the running edge (6) or the inner lateral edge (7) by means of a first copying probe element (43) that can be adjusted transversely to the rail (2) and processing the running edge (6) and/or the driving surface (5) of the rail (2) by means of a processing tool (40) coupled to the first copying probe element (43), characterized in that either the outer lateral surface (8) of the rail (2) to be processed or a lateral surface (7', 8') of the parallel rail (2') is temporarily touched by means of a second copying probe element (45), or the outer lateral surface (8) is touched by means of said second copying probe element after the first copying probe element (43) has been adjusted, and either the processing tool (40) is coupled to the second copying probe element (45) and at the same time the coupling between the first copying probe element (43) and the processing tool (40) is deactivated, or the processing tool is coupled to the adjusted first copying probe element (43).
