During milling, the cutter rotates along a horizontal axis and the side of the cutter removes material from the workpiece. A vertical milling machine, on the other hand, orients the cutter vertically.
These massive burrs absorb heat generated during milling, and that helps keep the flour cool so as not to spoil the natural oils. The size gives a much greater grinding surface, so they mill much faster.
The precision and surface finish obtained through grinding can be up to ten times better than with either turning or milling. Grinding employs an abrasive product, usually a rotating wheel brought into controlled contact with a work surface.

During startup tests and early operation at the Henderson mill, it was found that the m (28 ft) SAG mills could grind about 91 t/h (100 stph) autogenously, using no balls. Successively higher tonnages were achieved with 76 and 101 mm (3 and 4 in.) balls.
The mill is very loud when running and a ready supply of liquid nitrogen must be available during milling. Also, sieves are not part of this method, so production of samples of a certain range of particle sizes is not possible using this equipment.

Even better, if you are milling around the outside profile (peripheral milling), there may be plenty of clearance for chips to fall away and you could use a 4 flute cutter on aluminum. A counter argument to using more flutes or inserts is that fewer flutes/inserts are less prone to chatter.

The roller mill would break the grain to produce floury middlings. The floury middlings could be bolted and purified to remove some of the bran. Then the middlings would be reground using a slower grinding speed and there would be a more extensive bolting to extract as much flour as possible.
The reason that the "American" or "flat grinding process" was also called "low milling" was that the upper runner stone was set low or close to the bottom bed stone during milling. In "new process" milling the runner stone is set "half as much higher" above the bed stone as compared to low milling.
Grinding Roughs Out a New Niche Tyrolit Advocates a Patented Grinding Process for Rough and Finish Machining of Aerospace Parts. In the past, grinding has been a process that was primarily relegated to machining for final dimension accuracy and surface finish.

During ball milling, balls are subjected to three conditions: impact, abrasion, and corrosion. Much effort has been made to simulate these conditions in the laboratory. The impact of balls in mills is known to result in fracture and spalling, but spalling has been especially difficult to duplicate in the laboratory.
Grinding occurs on the wheel’s rim, and without a proper flange, the wheel could break. Depressedcenter wheels—types 27, 28, and 29—that are larger than 5 inches in diameter require specially designed adapters—a large back flange and nut—because of their shape and use.
