Milling cutter types include end mills, face milling cutter, flat milling cutter and so on. Typical milling processes include milling, chamfering or milling, milling, milling, milling, milling, and so on.

    Commonly used several end mill design types include: square head double-edged end mill, like the drill as the workpiece for vertical milling or side milling. Their end teeth extend to the center of the milling cutter, so they can be inserted and milled. Some three-edged end mills can also be used for milling. Double-edged and three-edged end mills are suitable for processing non-ferrous metals. The ball double-edged end mill can be used for milling round bottom or rounded edges.

    Compared with the double-edged end mill, the square head four-edged finish milling cutter is smoother and can keep the blade sharpness for a longer period of time, but it can not be inserted. These milling tools are best suited for cutting ferrous metals. Compared with a four-blade finishing end mill, a four-edged rough end mill can cut metal more quickly with smaller machine power, tool deformation and vibration, and its chip breaker can produce finer, more controllable Good chip.

    The helical saddle of the end mill reduces machining flutter. In processing, one or more points of the helical groove are always in contact with the workpiece and the metal material is continuously cut so that the machine is subjected to a continuous load, unlike when the tool is machined with a straight groove, The impact load is generated when disengaged. Although the manufacture of spiral groove tool is more complicated than the manufacture of straight groove tool, the cost is higher, but the processing flutter reduction and processing surface finish to improve its value for money.
