Hardness meter BRE AUT SOR for automatic Brinell hardness testing of train wheels. Automatic plant with transfer tool to alternately move two wheels throughout all positions (loading, measuring and unloading). This hardness testing system was the first plant we designed for a major industrial group in Eastern Europe for automatic testing of train wheels. Its reliability and full sustainability (24 hrs a day) have contributed to the diffusion of other machines present in this site for the same application. The plant in question is able to test hardness both of the finished wheels and the unfinished ones with preparation by means of lamellar grinding wheel or by milling, as you can see in the video clip.
