Flow drilling technology and thread forming - An economical and secure connection in hollow sections and thin-walled components

Abstract

Detachable and highly loadable screw connections can only be realized in thin-walled components and in particular hollow profiles with great effort. The flow drilling technology and subsequent thread forming represents an economical and technically interesting manufacturing alternative. With Flow drilling, a bush is generated by a fast-rotating carbide taper mandrel and a high resistant internal thread can be produced in a subsequent manufacturing process. Conventional weldor rivet nuts can be replaced in many application areas.
