Can be used for 1st Operation only Deadlength Actuation Eleminates part movement when Clamping Case hardened, optimising the rigidity, strength and durability. Varibore Collets have a large range allowing for easy holding of Rough Bar Klamp CRS60 collet chucks are suitable for collets which have a large gripping range. Allowing the collet chuck to handle very rough and unfinished bar, preparing it for a high accuracy second operation. Workpiece remains in a fixed position during actuation, allowing for precise z-axis positioning. A tapered sleeve is pushed forward, compressing the collet and gripping the workpiece

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.

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 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.
