Externals clamping - Import export

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.

Flange plate, piston and body rust-resistant, bright. Screws electro zinc-plated. Collet red or clear anodised. Note: Machinable collet system with base plate for mounting on 50mm pitch grid plates. The flange plate can be used for external or internal clamping collets. The contour of the workpiece to be clamped is machined into the collet. Free-form and asymmetrical contours can be clamped. The integrated spring package generates a clamping force of 5.8 kN. The clamping force can be raised to 43.5 kN by pneumatic post-clamping. The clamp is released by blowing compressed air onto the lower piston surface pushing the piston upwards and releasing the clamping force on the collet. Clamping travel 0.2 mm. Repeat accuracy < 0.01 mm. Accessory: Collet for external or internal clamping 03179

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.

Pneumatic gripper with 2 or 3 concentric fingers Single acting with rear central air connection High clamping force External clamping and vertical using only Without detection Screwing gripper technology The technology of this gripper allows it to develop a very large clamping force (about 10x the force of a gripper) so as to obtain the necessary tightening torque in the following applications – screwing cosmetic or hygiene bottles, with or without spout – screwing of pots or cans with torque control – screwing of thermostatic subassemblies – screwing push buttons The central rear pneumatic supply and single acting makes it easy to mount on a rotating joint. Screwing bottles with pump spoutThe wide angle opening version is generally used for screwing vials with pump spouts. The 2finger version makes it possible to tighten square or prismatic caps, but also to reduce cycle time by let go the bottle radially by opening the gripper at the height of clamping

The main function of the rigid shaft coupling is the safe and backlash-free connection of two shafts by means of friction. For example between a drive shaft and driven shaft and mainly to transmit torque. Shaft couplings consist of a connecting sleeve and two external clamping systems. They are not separable like flange coupling. The external clamping systems generate a backlash-free connection by pressing the connecting sleeve onto the shaft ends. The external clamping system does not transmit any torque or moments between the shaft ends, they just provide the necessary clamping forces. Those external clamping systems are not part of the flow of forces, but the connecting sleeve is. The couplings have to be installed by moving them onto the shaft ends followed by tightening of the external clamping systems via bolting. To achieve proper operation and a sufficiently high coefficient of friction, the contact surfaces at the shaft extensions must be free of grease, dry and clean....

When turning outside diameters, it is necessary to consider which clamping system should be used and which components will be made most often. This is because if larger components are to be turned (and therefore with correspondingly greater depths of cut) a different system must be used than when turning smaller components with a finishing pass. Determining the cutting direction and tool holder A turning tool which works from right to left is called a right-hand turning tool because it machines the right-hand side of the work-piece (when looking at the tool point, the main cutting edge of the turning tool is on the right).
