ADAPTIVE DFS Application


The patented adaptive assembly unit ADAPTIVE DEPRAG FASTENING SYSTEM can prescribe and monitor the feed speed and feeding procedure. The constant data reported by the control modules enable the precise and automatic recognition of all relevant penetration points. The fastening system autonomously performs Time-critical and essential parameter changes.


DFS Closed Loop


  Highest Process integrity
  Shortest possible cycle times
  Enhanced funnel forming
  Optimized thread forming
  Lower forces on the fastener, product, and equipment
  Reduced set-up time
  Designed for new materials, fasteners, and joining methods

Optimal processing parameters, independently from the tolerances

The fastening system autonomously performs time-critical and essential parameter changes; it ensures the ideal processing parameters, independent from the product's tolerances or fastener. It significantly reduces the effort of preliminary analysis and characterization. Costly and extensive repair procedures - caused by imprecisely formed holes, jammed screws, or ruined threads - are minimized.
The processing-parameters are automatically optimized to guarantee that the parts to be joined (fastener and product). Extensive real-time processing and equipment data are logged for each join. DEPRAG's software tools allow for a simple analysis of the results and trends.

Top flexibility during the processing of multiple materials

Separate electronic regulation of the EC-Servo screwdriver and the EC-Servo stroke technology, combined with the extensive parameterization possibilities, ensure the highest flexibility during the processing of various materials and material combinations.

Prepared for new materials and fasteners

The implementation of unique tightening sequences for new fasteners and materials is possible. The controlled feed stroke allows exact positioning and transition-points to be clearly defined, especially for the assembly of more modern materials such as carbon-fiber (CFRP).
