The dynamic safety brakes in the ROBA®-linearstop series work according to the fail-safe principle. The braking force is provided by pressure springs and transferred backlash-free via a conical surface onto a collet. This collet clamps the brake rod continuously, without changing its position. In closed position, the brake is able to withstand loads in both directions of motion. Dynamic braking actions can be achieved from speeds with a maximum of 2 m/s.
Safety brakes of the ROBA®-linearstop series are designed for dynamic braking applications and can be mounted directly onto standard cylinders according to DIN ISO 15552.
Dynamic stops were tested according to the Trade Association testing requirements on the mayr®-Drop Test Stand. In compliance with the Trade Association requirements, the tested elements are switched a million times statically and load-free, and a million times with load assumption. At every thousandth switching, they are braked dynamically from motion. The ROBA®-linearstop brake unit achieved 30,000 dynamic brake applications in fatigue tests with a maximum load and is therefore substantially better than the Trade Association testing requirement, which only stipulates 1,000 dynamic brake applications.
ROBA®-linearstop safety brakes can be mounted directly onto standard cylinders according to DIN ISO 15552. They can also be integrated simply, quickly and without complicated adjustment into different drive constellations. In contrast to other linear braking systems, the ROBA®-linearstop does not have to travel on the carriage. Supplying the pneumatic lines is therefore simplified. The brake can be screwed to a static machine component. The cylindrical piston rod is guided through the central bore of the brake and connected to the carriage of the linear drive.

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
