PROCEDURE FOR THE STATEMENT OF THE GEOMETRICAL ACCURACY OF A LINEARFUEHRUNG.

A measuring device, whereby a measuring body (9), to which is appended a measuring head (6) carrying lenth-measuring sensors (10), is mounted approximately parallel to the linear guiding mechanism to be measured. The measuring head (6) is held on a measuring arm (4) mounted in a base (5) on the linear guiding mechanism (1). The distances between two mutually perpendicular planes are measured by means of the length-measuring sensors (10), and the individual deviations for rolling, pitching, yawing, straightness Y and straightness Z of the linear guiding mechanism are derived by calculation using a simple and cost-effective measuring technique and equipment in comparison with known mechanisms.

Multi-station machine tool

A round table (40) is rotatable around a vertical axis in relation to the machine frame. For creating free space for machining of a workpiece arranged on the round table with the machining unit (66) the support (70) has a vertically extending section with wedge-shaped cross-section, so that the wedge points are directed in a radial direction against the vertical axis. The wedge point encloses an angle which is less than approximately 45 degrees. A ring-shaped connecting device (80) is incorporated, which is firmly connected with the upper support section of each of the supports (70), in order to increase the stability and the rigidity of the frame formed from the supports.

Device for producing relative motion with two translational degrees of freedom

A device for producing relative motion with two translational degrees of freedom between a spindle means ( 95, 195, 295, 395 ) with a spindle which bears the first part of a first pair of parts formed from a workpiece and a tool, and a retaining element for holding the second part of the first pair of parts, has a first base part to which a first part of a second pair of parts which is formed from the spindle means ( 95, 195, 295, 395 ) and the retaining element is attached. The movement device furthermore comprises a second base part, and at least one of the two base parts can be moved in a straight line with respect to the other along a linear guide with a first translational degree of freedom. A support for bearing the second part of the second pair of parts is coupled to the second base part to be able to swivel by means of a swivel joint around a swivel axis which is located at right angles to the linear guide such that the second part of the second pair of parts can be moved by actuating the swivel joint with a second translational degree of freedom on a circular path. The reaction forces and moments which are formed in the machining of the workpiece with the tool are accommodated by the swivel joint which is made stiff; this makes it possible to make the drive means for actuating the swivel joint lightweight. The movement device as claimed in the invention is relatively simple to produce, dynamic and moreover has a high ratio of useful working space to the required construction space.
