New TRIBOS Clamping Device: Compact, Efficient & Quiet

5 December 2011

The TRIBOS polygonal clamping technology from SCHUNK is one of the world’s most comprehensive programs for high-precision tool clamping. From micro to volume cutting, the patented clamping sys-tem delivers permanently high true-running accuracy, convincing vibration damping and the possibility to pre-adjust the length to exactly where you want it. The completely modified universal clamping device launched at the recent EMO show, now clamps all TRIBOS mountings quickly, precisely and energy-efficiently.

The fully automatic TRIBOS SVP-4 clamping device is more compact and lighter than its predecessor. Moreover, a new type of pump ensures that the device works more quietly. On request, it can be actuated with a 220V alternating current from the grid, or for mobile use by battery. An intuitive operational concept simplifies the clamping operation. The required clamping pressure for tool change is continuously adjusted via a controller. Then the mounting is automatically actuated with the defined pressure in no time at all. Maintenance and service intervals can be individually defined and displayed. The design of the TRIBOS SVP-4 is particularly maintenance-friendly. In order to increase sustainability, software updates can be installed with a mini USB interface.

The TRIBOS polygonal clamping technology is available for all con-ventional machine tool interfaces. It is used in the automotive, aero-space, mould & die, medical technology and in the machine and plant building industry. The one-piece mountings are mechanically resistant to outside pressure and permanently ensure a maintenance and wear-free clamping. Endurance tests prove that even after thousands of clamping operations no material fatigue will occur. Since the mountings are radially deformed during the clamping operation and there is no expansion in length, tools of a minimum length tolerance of 0.01mm can be adjusted.

This is an important advantage compared to thermal shrinking chucks where the length reduces during the cooling phases. The complete clamping operation is carried out in 15 to 20 seconds. Moreover, tool change is at ambient temperature, so it is completely safe for the operator. This eradicates the need for cooling lubricants that evaporate during heat shrinking or expensive energy-intensive heat shrinking units where an exhaust air plant has to sometimes be installed. The TRIBOS clamping device won’t empty your wallet or endanger the health of your operators.
