How To Choose a Stepover for 3D Profiling - CNCCookbook ...

To put real numbers on this, that would be equavalent to a .012, .025, and .042″ stepover for a .125″ ball mill. Stepover =1/10 of diameter. Stepover =1/5 of diameter. Stepover =1/3 of diameter. As you can see, the change in quality is so dramatic that you might be tempted to always use the smallest stepover possible.

Ball mill - Wikipedia

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles, and stainless steel balls.

Material Movement Inside a Ball Mill - bulk-online

In dry grinding, material is transported through the mill by medium-high velocity air that is injected at the inlet or mill feed end. As the mill rotates, mineral critical size fines are brought to the ball charge surface and are suspended and liberated by the injected air velocity currents and swept out the exit port.

Miller gave the example of machining steel, 4140. With a conventional 4" face mill with seven teeth, as listed in the tooling catalog, you'd take a 0.120" depth of cut, with 650 SFM, and a feed of 0.012" per tooth. This would give you feed rate of 52" per minute, and you'd remove 25 cubic inches of material per minute.
