Can anyone suggest manufacturing method to make spherical parts by forging?

05 May 2015 1 4K Report

Hi People. I need information about the hot forging process to make milling balls. This part is used in mining to break mineral stones.

I attach an schematic image about the process as help.

Jorge Madias

Daniel, the process is the so called cross rolling (for wet grinding)
