The Company

The company Friedrich Maschinen- und Werkzeugbau GmbH, or, more concisely, FMW, was founded in the year 1948 at Remshalden near Stuttgart. The family-run company develops and produces riveting machines, special-purpose machines and electrically operated presses for the automotive, fittings and electrical industries.

Riveting Technology Pioneers

The riveting process

Riveting as one of the oldest processes of connecting two components in an inseparable way is known since early history. It is impossible to imagine how present-day manufacture could do without an up-to-date riveting technology.

The invention that revolutionized the riveting world
“The Radial Point Riveting Technology by Friedrich”.

Radial Point Riveting

The end E of the riveting die describes a hypocycloid loop-path S. Here, too, the longitudinal axis of the riveting die intersects the riveting spindle axis in point M. Due to the hypocycloid drive the angle of attack of the die constantly changes between 0° and X°.

The shaping of the rivet is done by point contact, forming the rivet material outward from the centre.

The advantages of the radial point riveting technology:

  • low effort combined with a high riveting power
  • low-noise and uniform rivet shaping
  • low transverse forces, therefore workpiece fastening is easy
  • particularly suited to meet quality assurance requirements due to the vertical riveting die
  • minimum friction, little heat development and a smooth rivet surface
  • gentle change to the rivet material structure
  • no rotation of the die, therefore also stamping is possible
  • allows achieving an easily dimensional  bearing stress

Roll-forming

Bearing housing

Friedrich has been developing and building rolling machines since 1983 to complement the company’s assembly systems product line.

The rolling heads initially were intended for the rolling-in of bearings in housings where special requirements towards strength, tightness and freedom from chips had to be met. The drive units are based on Friedrich’s proven hydraulic rolling units.

With customers asking for more versatility and all-around properties, a comprehensive product range developed over time.

This is why we can today offer a great variety of internal and external rolling heads in different variants. These rolling heads have either fixed or adjustable effective diameters, and in some cases, they also possess quick-change systems or an additional radial feed.
