Compact ring indexing table

The RST series is pneumatically driven and is available in two different sizes with the RST18 and RST24. The key differences are the footprint (70x70mm and 100x100mm), torque (1.2 and 4Nm) and the maximum axial force on the cycle ring (1950 and 3400N). 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 and the cycle types can be changed in any order and any number of times. Thus, the RST series allows the working process to be stopped to return a few steps and repeat the processing step in question if an error occurs. The angle adjustment can be set to 4, 6, 8 or 12 steps. Hydraulic shock absorbers are used as end position dampers in both directions. According to Schunk, the repeat accuracy of the angle of rotation is less than 0.03° with an axial and radial run-out of the cycle ring better than 0.02mm. As only the cycle ring rotates in the RST series, it has a large fixed central section which makes it easier to add additional components and assemblies. It also allows additional assemblies to be supplied with compressed air without the air hoses having to follow any rotating movements of the ring indexing table.
