Vertical Milling Machine is Most Common • Milling machines are very versatile. They are usually used to machine flat surfaces, but can also produce irregular surfaces. They can also be used to drill, bore, cut gears, and produce slots. • The type of milling machine most commonly found in student shops is a vertical spindle machine with a ...
What is a CNC machine? Originally milling machines were manual in operation. Movement of the part or tool was often accomplished by manually turning handles that turned the ball screws or manipulated various levers of the machine. Basic automation allowing the machine to move in one direction, once the part location was set by the machinist.

Ball milling is a way to exfoliate graphite using lateral force, as opposed to the Scotch Tape or sonication that mainly use normal force. Ball mills, like the three roll machine, are a common occurrence in industry, for the production of fine particles. During the ball milling process, there are two factors that contribute to the exfoliation.
