The automatic tool changing system MPS 631 is the perfect answer to the demand from a wide variety of industries for a solution with maximum flexibility. The new tool changer, which is based on the proven MPS 630, is geared towards applications with different production technologies that depend on attaching as many transmission modules as possible.

Thanks to the sophisticated structural design, the modules can be mounted in the tool changer using the large number of available module slots and thus occupy minimal space. With the MPS 631, users can enjoy a high degree of constructive freedom.
