    20.06.2020 · Post-grinding rail roughness level has a big impact on the performance of the rails. For cases where roughness values were particularly low, flange-climbing derailments occurred [7,8], when a wheel of a rail vehicle climbs up a rail.The names used for relevant parts of wheels and rails and a typical sequence of events leading to a flange climbing derailment is shown in Fig. 2.

    Fig. 1 shows the experimental set-up used in the investigation, a modified CNC 3-axes milling machine. In this set-up, the spindle with the grinding disk has the three translational degrees of freedom x, y and z, whereas the workpiece is stationary (Fig. 1a). An asynchronous electric motor drives the precision spindle by means of pulleys and a belt at speeds ranging from 1′000 to 22′000 rpm.

    Dispersion of organic molecules during grinding can occur via two basic mechanisms: gas phase transfer and surface contact transfer. This can eas - ily be proved in simple grinding experiments in a closed batch mill. For instance various alcohols with boiling points below grinding temperature improve grinding efficiency significantly (Table 2).
