Nowadays all kinds of machine tool have been used in manufacturing industry, such as turning, milling, grinder, planer, and so on, but among them, milling machine is the most useful machine tool, because we can produce complex surface through using milling machine. Today, we will study and know a new kind of milling machine which is famous for its high efficiency and cleanness, it is called whirlwind milling machine. Whirlwind machine is a kind of machine which we add the high speed thread devices to normal turning machine, through using CBN tool which is clamped in the high speed milling cutter, we can mill the thread on the workpiece, because of its high speed which is more than 400m/min, high working efficiency, and cool strategy which use compressed air to get the chips out of the thread of the workpiece, it is becoming more and more important and popular. Whirlwind machine can also realize dry cutting ,heavy load cutting and ultra high speed cutting, the surface roughness can reach 0.8 um, because the turning speed of spindle is slow, so the motion accuracy of machine tool is accurate, and we can get high dynamic stability. Here are the motion of the whirlwind machine, the main motion is the high speed turning of the mill cutter, the supplementary motor is the slow turning of the machine tool with clamped workpiece, the feed motor is the slow movement of the mill cutter at x direction, and we should adjust the angle of the mill cutter according to the thread lead angle. The application of the whirlwind machine is spreading all kinds of machinery, for example, the sprite which we drink when we feel thirsty is involved in using this technology, we can manufacture the cap using whirlwind machine, and we can also manufacture all kinds of bolts and ball screws. On the whole, the whirlwind technology is widely used in daily life, and we can keep improving the feature of the whirlwind machine, in that way, we can keep doing great in machinery.
