WS 7.3540 Workholding Systems ZH concentric clamping, hydraulically operated jaw widths 100, 125 and 160 mm Advantages ●●High repetitive clamping and positioning a ccuracy of ± 0.01 mm ●●Opening stroke limitation by means of a djusting screw or optionally proximity switch ●●High stability and very good protection against swarf ●●Clamping edge for clamping claws ●●Customer-specific mounting holes ●●Fitting key, positioning and mounting holes for standard and special clamping jaws ●●Crosswise keyway for positioning ●●Central lubrication Application Hydraulically-operated concentric workholding systems for clamping of workpieces on machining centres, automatic saws or end machining. The workholding systems are also used in special machines or as a fixture element. Particularly suitable for automated processes or harsh environmental conditions. Accessories ••Clamping jaws on request ••Accessories for fixing and positioning see page 2 ••Hydraulic pressure generators on request Description Due to the play-free adjustment of the synchronisation mechanism clamping and positioning accuracies of ± 0.01 mm are obtained. Long slide guides and the compact encapsulation of the moving parts ensure high process safety and durability. The large clamping strokes enable the production of a large number of workpieces in one workholding system. Also large jaw openings can be realised in very compact workholding systems. The opening stroke can be adjusted by means of an adjusting screw or optionally by a proximity switch. Consultation Our experts will be pleased to advise you also on site, and work with you to find the optimum clamping solution. Extensive information such as drawings and CAD models are available on request.
