Centerdrill - Flow Punch Forming - 58596 The Flow Punch Forming Processcenterdrill

With flow punch forming bushings or eyelets can be produced in thin-walled metals without cutting up to a wall thickness of 12 mm. Bushings or eyelets can be obtained with up to 4 times the original thickness of the material in diameters of 1.8 mm to 32 mm. Flow punch forming is based on a combination of axial force and relatively high speed, which results in heat from friction. The frictional heat and high contact pressure plastify the material and enable the centerdrill to go through the material in a matter of seconds.

The Advantages of Flow Punch Forming Which materials can be processed with ?centerdrill Requirements for Flow Punch Forming

Time savingLess material and lower weight due to the use of thin profilesIncrease in the drawing forces of threads (thread forming)Tightness of the clearance holesDetatchable connections - The basic material remains unalloyed No reinforcing welding, riveting down, or welding screw nuts necessaryIncrease in hardness - for example less wear with multiple connectionsOnly one basic material, thus avoidance of electrochemical corrosion High load capacity of bearing bushes Flow punch forming can be used with virtually all thin-walled metals (excluding tin or zinc); for example all welding steels, stainless steels, aluminum, copper, brass, bronze, magnetic materials and special alloys.Some application examples: Any column drilling machine with sufficient power or NC/CNC machining center, etc., with the required speed and kilowatt output is basically suitable for flow punch forming.For secure clamping of the centerdrill , a special collet chuck with cooling ring was developed with which the heat can be dissipated ideally. For optimal concentricity a special collet is used for locating the centerdrill. Spezialfutter und Spannzange
