A gauging device for a metal working machine comprising two parallel hollow sections separated by a predetermined distance and having disposed therewith in use ball screw drives for each section having a pulley engaged with an endless belt, the endless belt (preferably a nylon covered steel core belt for example as manufactured by Breco-flex of Germany) driven by a separate servo motor having a second pulley engaged therewith, preferably the belt being engaged with an idler pulley on each side of the servo motor, whereby the one servo motor drives both ball screw drives each disposed with one of the two hollow sections. The center to center spacing of the ball drives is not as critical as with conventional known methods of linking drives, i.e. shaft and right angle gear box and drive shaft arrangements.
A gauging device for a load to accurately position the load in relation to at least one axis of reference (for example X, Y, R1 and R2, or Z1 and Z2) in relation to a predetermined position whereat a further operation for the load will take place (such as bending), the gauging device comprising a hollow continuous closed extruded section (for example in cross section), the section being provided with details with the internal and the external walls of the section, (for example cutouts, channels, reinforcing ribs and guide rail receiving portions), the details providing precision motion of a carriage within the section, the carriage bearing the load to and from the predetermined position in relation to at least one axis of reference, the gauging device having driven means, for use in engagement with driving means at one end thereof said driven means being disposed within the hollow continuous closed extruded section, the driven means engaged with the carriage;
A low profile hollow extruded aluminum section designed for torque resistance to an external force for a gauging unit for a brake comprising a guidance system in use disposed within the hollow section, the section being provided with details with the internal and the external walls of the section when manufactured, (for example cutouts, channels, reinforcing ribs and guide rail receiving portions to retain the guide rails in use), the details providing precision motion of a carriage within the section in use, the carriage bearing a load to and from a predetermined position in relation to at least one axis of reference for the brake in use, wherein the carriage has disposed therewith four wheels to engage rails disposed within the section, two wheels being fixed in position with respect to the carriage and two wheels being adjustable in position during manufacture to precisely set the reliable motion of the carriage.
