The inputs can be optimized for rigidity, feed force, or feed speed, depending on requirements. The high torsional rigidity of the RP+ gearboxes, combined with the tilting rigidity, C2K,lin, and engagement spring stiffness, Cγ, together with a highly rigid design, have a positive effect on the natural frequency and thus on the control behavior of the machine. ![](https://www.wittenstein-group.com/fileadmin/_processed_/f/9/csm_cynapse-produkseite-element_slider_3783d47093.webp) With cynapse® and smart services, you can unleash the full potential of your drive system: sensor data is processed, visualized, and analyzed intelligently.
