High clamping forces in confined spaces are ensured by the miniature clamping stations from the SCHUNK VERO-S NSL mini 100-25 series. The power-dense 1-way, 2-way, and 4-way clamping stations are specially tailored to the requirements of modern small parts production: Completely sealed, the used clamping modules prevent the ingress of chips or dirt into the module interior and causing disturbances. At the same time, a retreaded drive increases the pull-down forces: Each clamping module achieves a pull-down force of 6,000 N thanks to a patented fast and clamping stroke and activated turbo function. Depending on the thread used, the holding force is 15,000 N (M6) or 25,000 N (M8). With dimensions of 199 mm x 199 mm x 40 mm, the quadruple clamping station achieves pull-down forces of 24,000 N and holding forces of 60,000 N and 100,000 N, respectively. Since the rigidity has also been increased, significantly higher tilting moments can be accommodated.

The compact miniature clamping stations SCHUNK VERO-S NSL mini 100-25 (here as a double clamping station) have high pull-down forces, high rigidity and are completely sealed.

Robust and durable

The mini clamping stations are locked self-retaining and form-fit using a spring assembly. They do not consume any energy when actuated. The corresponding quick-release couplings for opening by compressed air or for activating the turbo function are placed in an elevated position and are thus particularly easy to reach, without restricting the accessibility of the workpieces. Large contact surfaces between the clamping slides and pins minimize surface pressure in the clamped position, thereby reducing wear on clamping modules. To increase the service life, all the functional parts of the clamping modules, such as the base body, clamping pin, and clamping slide, are made of stainless steel. The other components of the clamping stations, in turn, are chemically nickel-plated or hard-anodized and are therefore also stainless.

Extensive modular program

The VERO-S NSL mini 100-25 clamping stations extend the SCHUNK VERO-S mini modular system. Permanently mounted on the machine table, they precisely pick up a wide variety of clamping devices from the SCHUNK NSE mini range and enable quick set-up procedures. Longitudinal alignment grooves in the longitudinal and transverse directions simplify the placement on the machine table. In addition, the 2-way and 4-way clamping stations are equipped with center holes and alignment edges. On option, the clamping stations can be provided with additional screw holes.
