For a wide range of manufacturing process clamping parts with process reliability, just with the power of the atmosphere, requires the use of vacuum chucks.

High accuracy of chucks can normally be achieved using self-stable but completely light-proof designs, which means use in laboratories or optical areas is often restricted.

Application possibilities incorporating light transmittance, either via built-in lighting elements or via transparent structures, are increasingly in demand.

Together with 3-D-Micromac AG in Chemnitz Horst Witte Gerätebau Barskamp KG developed a light transmitting vacuum chuck.

Thus optical recognition systems can now be used for detecting components while parts are clamped. Other transparent objects such as foils can be gently clamped with the help of a light transmitting vacuum chuck for optical inspection.

Witte is showing this patented vacuum system for the first time in operation at the EMO exhibition.
