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.

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

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.

Repetition Accuracy of 5 micron Extremely High Clamp Forces Low wear due to Nitrogen Hardened Surfaces Suitable for Internal or External Clamping BEST hydraulic centric vices are a no compromise solution to repeating and long running 4th and 5th axis workholding. BEST have focused on the production of high accuracy, high rigidity vices. These vices are suitable for both internal and external clamping. They offer very high clamping forces and repeatability of 0.005mm and a centring accuracy of 0.01mm. The Hydraulic vices also have the following options: Clamp Path Monitoring, Fixed Jaw, Central Lubrication System and Positive Air Pressure to prevent swarf ingress.

Repetition Accuracy of 5 micron Extremely High Clamp Forces Low wear due to Nitrogen Hardened Surfaces Can be Adapted to suit other manufacturers Zero Point Systems BEST mechanical centric vices are a no compromise solution to varying 4th and 5th axis work. BEST have focused on the production of high accuracy, high rigidity vices. These vices are suitable for both internal and external clamping. They offer very high clamping forces and repeatability of 0.005mm and a centring accuracy of 0.01mm. The machincal vices can be converted to RPCG type to suit the BEST Realpoint Zero Point System The BSMG range have been designed with an enclosed lead screw to reduce maintenance time.
