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.

Collets for clamping external contours. The contour of the workpiece to be held is inserted into the collet. Free-form and asymmetrical contours can be held. The collet mechanism enables a secure clamping of the workpiece. Clamping travel per collet segment (8x) max. 0.15 mm. Workpiece repeat accuracy: ±0.03. Collet repeat accuracy: ±0.02. Matching adaptor 03167.

The lateral clamping screw tightens the jaws and clamps the workpiece on the circumference. The simple and compact design allows 2 workpieces to be clamped. The clamping travel is max. 0.5 mm. The jaws must be pre-tensioned before machining the contour, the supplied clamping ring is used for this purpose.

It is recommended that the cam lever is in a vertical position when the collet is positioned in the bore. The function of the clamping system was tested in bores with tolerance H7. All values for retaining force are guide values and are given without safety factor. The suitability for the respective application must be checked by the user. Advantages: Two components can be joined together without tools. The components are perfectly centred in the clamped state. The compact design means that the mandrel collet with cam lever can even be used in blind holes. There are no specific dimensional requirements for the holes. Additionally, the surfaces and design do not need to have any specific properties. Functional principle: The clamping system is inserted in the hole in the open state. At the beginning of the locking process, the mandrel collet expands and clamps itself in the lower component. The integrated disc spring assembly creates a positive down force

The mandrel collet is used in small through bores to position and clamp workpieces. Clamping is carried out manually from above using a hex key. The mandrel diameter can be ground to suit the application. The bore for the mandrel should have an H7 tolerance. D min = smallest permissible diameter to which D can be ground. applicable for holes from Ø5 to Ø12.5 mm compact design, small installation space simple handling mounting in any position different installation types possible surface pressure protects the workpiece surface individually adaptable to the diameter Technical data: The tightening torque max. Nm given in the table refers to the spanner size AF2. Assembly: If required, diameter D can be adapted to suit the diameter being held. To do this, expand the mandrel collet ca. 0.2 mm over the required diameter. Grind the OD of the mandrel collet to suit the ID of the workpiece bore.
