  • Mill (grinding) - Wikipedia

    Ball mill. A typical type of fine grinder is the ball mill.A slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grind material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%.

  • Why Use a Single Flute End Mill? - CNCCookbook: Be A .

    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.
