Ball End Mills | Regal Cutting Tools

The design of ball end mills forms a hemispherical cutting action identical to the diameter of the tool. Because of the shapes required in these products it's common that multi axis machining centers are used for this work. They can also be used in a secondary way to form a radius at the juncture of perpendicular surfaces.

Milling cutter - Wikipedia

The diameter may be different from the diameter of the cutting part of the tool, so that it can be held by a standard tool holder.§ The length of the shank might also be available in different sizes, with relatively short shanks (about 1.5x diameter) called "stub", long (5x diameter), extra long (8x diameter) and extra extra long (12x diameter).

Why Use a Single Flute End Mill? - CNCCookbook: Be A Better CNC'er

The answer is we space out more cutting edges (flutes) around the circumference of the cutter so that as the cutter is spinning, we get a lot more bites (chips) of the material. It's now pretty obvious. At a given surface speed, a 4 flute endmill can take 4 cuts at a given chip load (chip thickness) while a 2 flute only takes half as many.

Ball mill - Wikipedia

A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.
