Basic element modular single-roller tool system




The basic element is available in three sizes. The machining direction (internal/external) and the tool preload is set by an adjusting knob.



  • easy to use
  • adjustable tool preload
  • rugged tool design




Test Device


The test device is used to set and to check the required tool preload characteristics. With the dial gauge and the load cell it is then possible to correlate the tool preclamp with the rolling force to support constant process parameters.


  • easy to use
  • including certified hydraulic load cell
  • useable for diverse tool types
  • rugged design




Tool assembly and handling

Modular single-roller tool system



Classification force – spring deflection



Classification Force - Spring Deflection:
Unlock the Fixing screw (3), turn the spindle with spring package according to the scale. Relock the Fixing screw nut (3). Check the preload setting with the test device.


Turn ClockWise = preload increases
Turn counterclockwise = preload decreases

Adjusting the center height:
Loosen the clamping of the tool fixture. The center height is adjusted by the adjusting screw (5). The setting should be between 0 and 2 mm above the machining center line. Fix the clamping of the tool fixture. 



  • The preload of the tool during burnishing should be in a range between 0.1 and 0.5 mm
  • Coolant must be used at any time
  • Avoid interrupted cuts
  • The dial gauge helps to set up the tool, especially when using conventional machines

Please note: The occuring forces can be very high! For safety reasons always ensure a sufficient clamping of the tool on your machine
