Collet for external clamping

Enter the desired lever colour here. The standard colours are: Black grey clamping lever, traffic red push button. Orange clamping lever, black grey push button. Traffic red clamping lever, black grey push button. Where L ≥ 60 mm the thread length is 60 mm. On request: Other threads, screw lengths and special versions. Dimension “H1” available in other lengths at extra charge. Drawing reference: 1) flat point DIN 78

Swing clamps are used where low clamping forces suffice or where the clamping point must be free when mounting and removing the workpiece. The block form of the housing offers universal fastening possibilities. The magnetic piston is primed for electrical end position feedback. Including screw and lock washer for fastening the clamping arms (accessories). The swing action of the clamp should not be blocked. F1 = at 6 bar (max. operating pressure).

These centring clamps enable workpieces to be centred on and lightly clamped in a bore. The clamps have a wide expansion range. The series covers a bore range of Ø12 to Ø30 mm. To increase the centring accuracy the clamps with internal thread have a centring spigot (D2) for a locating hole. The centring accuracy is ±0.2 mm. Centring clamps with female threads fit on M6 grid systems (see illustration).

The collet is opened by applying compressed air to the "open" port. The collet is closed (for clamping) by applying compressed air to the "close" port. The pneumatic connections can be screwed on either from below or from the side. If the air is connected from below, the side ports must be closed. Machining the collet for external clamping: The negative form of the workpiece to be clamped is machined into the collet. Free-form and asymmetrical contours are possible. Different workpieces can be clamped quickly and securely by simply exchanging the collet. The collet can be milled down to height H2. This enables multiple workpiece contours to be machined into one collet. Repeat accuracy for workpiece: +/-0.03 Repeat accuracy after replacing the collet +/- 0.02 The collet radial clamping travel is 0.15 mm per clamping segment. To prevent damage the collet should not be tightened without a workpiece or clamping ring in place. The operating air pressure should lay between 0.45 - 0.55 MPa.
