GALL - RETT-16---
I rulli per la profilatura delle mole, se escludiamo i rulli diamantati, possono essere costruiti in HSS, metallo duro, o acciai fortemente legati. |
The crushing rollers for abrasive wheels can be made in HSS or in carbide or in high alloyed steel. But in any case must have a hardness of at least 64 HRC in order to guarant an acceptable life. Would be possible to use soft steel, but the life is too short.
