Unit is embedded with DFS software that helps in maintaining result and data, parameterization programs.

Original Press Release:

Adaptive DFS Deprage Fastening System

The new adaptive assembly unit ADAPTIVE DFS combines EC-Servo screwdriving technology with EC-Servo stroke technology

The constant data recorded by the control modules enable the precise- and automatic recognition of all relevant penetration points.

Time-critical- and essential parameter changes are autonomously performed by the fastening system. The system ensures the ideal processing parameter, independently from the tolerances of the product or fastener. It significantly reduces the effort of preliminary analysis and parameterization. Costly and extensive repair procedures that are caused by inaccurately formed holes, jammed screws or ruined threads are kept to a minimum.

The best possible processing-parameter that have been automatically adapted to suit any situation, guarantee that the parts to be connected (fastener and product), are subjected to the least amount of strain. The additionally captured processing-data allow an increased process documentation.

Separate electronic controls for the EC-Servo screwdriver and the EC-Servo stroke technology, in combination with the extensive parameterization possibilities, ensure the highest flexibility during the processing of multiple materials. The implementation of special tightening sequences for new fasteners and materials is possible. Especially for the assembly of future materials such as carbon-fiber and CFRP, the controlled feed stroke allows that exact positioning and trigger-points are clearly defined.
