Thermal friction drilling tool centerdrill

Flow punch forming with centerdrill is a process in which high-strength bushes or eyelets are produced in thin-walled metals using a simple operation without cutting. Instead, friction and feed pressure are used to heat and form the material.

The flow punch forming process may be used everywhere, where threads, bushings, soldering connections or through-holes are to be produced in thin-walled metals materials (e.g. steel plates, non-ferrous metals or high-alloy steels).

Flow punch forming can be used with virtually all thin-walled metals.

The standard versions include the centerdrill short and long models. They differ only in the length of the cylindrical part; the angle of the conical part is identical. When using these versions the material displaced against the direction of feed remains on the surface of the workpart and forms a collar.

Both models are also available in the flat version, with cutters ground into the belt that remove the collar in the same operation, resulting in a smooth surface.
