Schunk Introduces New Improvements to Compact Ring Indexing Table
The new RST-D has been strengthened in areas that help increase performance and improve lifecycle.
SCHUNK has greatly improved the RST-P series. The new RST-D has been strengthened in areas that help increase performance and improve lifecycle. The pneumatically driven RST-D is now available in three sizes with the RST-D 60, RST-D 87 and RST-D 134. Their key differences are the index plate diameter and torque.
The ring indexing tables can cycle either to the left or the right or alternate, without requiring any modifications. Switching is performed by the pneumatic actuation alone, and the cycle types can be changed in any order and any number of times. The RST series allows the working process to be stopped, to return a few steps and repeat the processing step in question if errors occur - a unique feature not offered by any other manufacturer.
The angle adjustment can be set simply to 4, 6, 8 or 12 steps, and on the RST-D 134 can be ordered with 16 steps. Hydraulic shock absorbers are used as end position dampers in both directions. The repeat accuracy of the angle of rotation is less than 0.03°, the axial and radial run-out of the cycle ring is better than 0.02 mm.
As only the cycle ring rotates in the RST series, its special feature is an unusually large fixed central section. This makes it easier to add additional components and assemblies, and features a large feed-through bore. For example, it allows additional assemblies to be supplied with compressed air without the air hoses having to follow any rotating movements of the ring indexing table.

3D Vision: Ensenso B now also available as a mono version!
This compact 3D camera series combines a very short working distance, a large field of view and a high depth of field - perfect for bin picking applications. With its ability to capture multiple objects over a large area, it can help robots empty containers more efficiently. Now available from IDS Imaging Development Systems. In the color version of the Ensenso B, the stereo system is equipped with two RGB image sensors. This saves additional sensors and reduces installation space and hardware costs. Now, you can also choose your model to be equipped with two 5 MP mono sensors, achieving impressively high spatial precision. With enhanced sharpness and accuracy, you can tackle applications where absolute precision is essential. The great strength of the Ensenso B lies in the very precise detection of objects at close range. It offers a wide field of view and an impressively high depth of field. This means that the area in which an object is in focus is unusually large. At a distance of 30 centimetres between the camera and the object, the Z-accuracy is approx. 0.1 millimetres. The maximum working distance is 2 meters. This 3D camera series complies with protection class IP65/67 and is ideal for use in industrial environments.
