The proposed cross rolling method can be used to form six balls at the same time, each ball with a diameter of 100 mm. When rolling six balls with a diameter of 100 mm, the minimal length of the rolls should be equal to 800 mm. If the rolls have a smaller width, the number of simultaneously produced balls should be decreased.

One of the most efficient methods of manufacturing balls for ball mill grinding media is skew rolling with helical tools. The concept of the rolling process for producing balls with the use of helical tools was developed at the turn of the 19th and 20th centuries [1,2,3,4].However, the intensive development of this method did not take place until in the 1950s, when the OAO EZTM (Moscow ...

The diameter of the steel bar is 4.95-5.05 mm and the diameter of the rolled balls which are semi- finished products is 5.3 mm. The friction between the die and the workpiece is so low in cold rolling that the rib-rising must be slow at first and fast later defined by the biting-metal condition, and the length of the helical groove sufficient ...

are considerably smaller than in the case of mill-ing. The limitation of the skew rolling process is maximal diameter of the rolled drills. The drill's proper geometry is achieved rolling drills of di-ameter not exceeding 20 mm. Above this diam-eter the drill forging has rounded edges, which cause lowering usable property of twist drills.
