Synthesis of Nanomaterials by High Energy Ball Milling
It is a ball milling process where a powder mixture placed in the ball mill is subjected to high-energy collision from the balls. This process was developed by Benjamin and his coworkers at the International Nickel Company in the late of 1960.

The general idea behind the ball mill is an ancient one, but it was not until the industrial revolution and the invention of steam power that an effective ball milling machine could be built. It is reported to have been used for grinding flint for pottery in 1870.
How Ball Bearings are Made - Sheldon Brown
For mass production of steel balls in the 19th century another method was chosen first. After all, not relatively soft stones, but steel had to be treated. On lathes, balls of a remarkable accuracy were cut off from a rod of steel and the ends machined to form a sphere.

Introduction to Milling Tools and Their Application
Ball end mills produce a radius at the bottom of pockets and slots. Ball end mills are used for contour milling, shallow slotting, contour milling and pocketing applications. Flutes Spiral-shaped cutting edges are cut into the side of the end mill to provide a path for chips to escape when an end mill is down in a slot or a pocket.
Milling cutter - Wikipedia
Milling cutters are cutting tools typically used in milling machines or machining centres to perform milling operations (and occasionally in other machine tools). They remove material by their movement within the machine (e.g., a ball nose mill) or directly from the cutters shape (e.g., a form tool such as a hobbing cutter).
