Overview Robot-assisted screwdriving system for flow-drilling screws (RSF25). The system creates detachable screw connections without prior drilling and compensates material variations and manufacturing tolerances. It is designed for applications with one-sided accessibility and mixed-material assemblies where high-strength, removable joints are required. Performance and process The RSF25 forms a metric thread directly in the elements to be joined, producing removable connections that allow disassembly. The method achieves high clamping forces and high loosening torques. Process parameters are freely configurable to adapt tightening profiles to the application. The joining process uses low heat input and supports one-sided screwdriving positions. Features Robot-capable system for integration on robotic cells Screw connections possible from one side (one-sided accessibility) Direct screw connection without pilot hole possible Forming of a metric thread in the component Compatible with other joining techniques (e.g. adhesive bonding) Compact design with optimized interference  Quick-change tool holder and automatic jaw opening Technical data (extract) RSF25 — Torque [Nm] — up to 15 EC drive [rpm] — up to 8,000 Max. axial force (at 6 bar) [N] — up to 3,600 Holding down force (at 6 bar) [N] — up to 1,400 Cycle time [s] — from 1.6 Technical changes reserved.
