Shortlist nomination for Raziol Tribometer 5100: Reducing development costs with a quick performance comparison for lubricants

Geschrieben von Hellmich, Tobias am . Veröffentlicht in Produkte


Raziol Zibulla & Sohn GmbH is introducing a newly developed testing system to determine the friction values for sheet metal forming using the Tribometer 5100. The friction testing equipment allows the immediate comparison of tribological properties for lubricants under the influence of various system and technology parameters.

The immediate performance comparison using Tribometer 5100 will reduce development costs. The attained values will also be used to fine tune the forming simulations and optimization of sheet metal forming processes. At EuroBLECH in 2018 in Hanover, the Raziol Tribometer 5100 was exhibited and presented to the public for the first time. The Raziol Zibulla & Sohn GmbH received recognition for this innovation at the “EuroBLECH Award” in the category of “Test and Measurement”.

The model test on the Raziol Tribometer 5100 enables the simulation of the friction conditions during sheet metal forming with determination of the friction coefficient μ between tool and material using the “flat metal strip” method. For this purpose, practical test conditions are achieved at the test facility by varying the system parameters  (e.g. lubricant types, sheet metal and tool materials and their surfaces, coatings and roughnesses) as well as the technological parameters (e.g. speed, test system surface pressure, over all load, Tooling temperature, lubrication quantity, etc).


With the aim of offering customers from the sheet metal processing industry a mobile and self-sufficient system for determining friction coefficients, the predecessor system Raziol Tribometer 5000 has already gained many years of positive experience in cooperation with industrial partners. The testing system developed from a research project has already been used successfully by many major companies as an important decision-making tool for the pre-selection of materials, lubricants and the use of suitable coatings.

The Raziol Tribometer 5100, presented for the first time at EuroBLECH, offers a more varied selection of system and technology parameter settings for practical test conditions in model tests. Based on the VDA standard, the contact area of the tool was increased to 10,000 mm². With a one-sided contact pressure surface, the most varied surface pressures can be set at different temperature conditions with this or with smaller tool contact surfaces.

The coefficients of friction can be determined precisely under the individual conditions of each individual case. The data is recorded with the Raziol measuring and evaluation technology in a targeted manner. The VISU 4000 is used as a touch and operating panel for self-explanatory operation and monitoring. The clear comparison of different lubricants is made by comparing the coefficients of friction. In addition, the friction coefficients determined can be used as input data for friction models in sheet metal forming simulations.

By setting the near optimum process parameters on the Raziol Tribomter 5100, the start-up phases of forming processes can be shortened as well as the reduction of rejects in the production process can be achieved. Sheet metal forming processors benefit from the following advantages using the Tribometer 5100:

  • Reduction of development costs (time savings in the Try-Out phase)
  • Reduction of process costs (targeted and application-oriented use of lubricants)
  • Increase in productivity (eliminating downtime in production processes)
