The indexing and clamping grips enable the positioning, securing and clamping of diverse positioning elements with just one product. Indexing is carried out using the indexing pin and the item is clamped using the end face of the sleeve. A protruding signal button means that the indexing pin is not completely extended.

Hardened and ground (HRC 56 +2). Note: The locating pins can be easily removed with an extractor.

Ball end locating pins are specially designed to ease the locating process. The tendency to jam, caused by the locating hole not being at right angles to the pin or by the pushing force not being parallel to the pin axis, is minimized by the ball-end form (see illustration).

Case-hardened. Toleranced diameter ground. Note: These centring pins are suitable for the central holes of our workholding elements 01148, 01263, 01265, 01267 and 01850.

When the positioning cone and bush are mated, the balls are pressed together within the rubbers elastic range and thus locate the two parts in which they have been fitted, with maximum accuracy. To ensure that the rubber in which the balls are embedded is deformed within the elastic range, one must merely ensure that the depth of the hole into which the positioning bush is later pressed is precisely observed. The positioning cone is supplied ready to fit into the positioning bush and must simply be fitted into the counterpart component. Henceforth, a precise zero point positioning system is in place.

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.

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 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.

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).
