Summary: Milling cutter of milling machine of numerical control of? of ≡ of few of Mao of car superintend and director is general comprise by component of bit, fixed position, clamping unit and cutter hub. Because bit has a variety of fixed position and clamp kind on cutter hub, bit locates the structure of component has different kind again, accordingly the configuration of milling cutter has a variety of, classified method is more also. Bit arranges means to be able to be divided mix for paper-cover structure establish outfit structure two kinds big.

1) paper-cover structure (bit radial is arranged) graph.

Milling cutter structure chooses numerical control milling machine

Milling cutter is mixed by component of bit, fixed position, clamping unit commonly cutter hub composition. Because bit has a variety of fixed position and clamp kind on cutter hub, bit locates the structure of component has different kind again, accordingly the configuration of milling cutter has a variety of, classified method is more also. When choosing, basically can range way according to bit. Bit arranges means to be able to be divided mix for paper-cover structure establish outfit structure two kinds big.
1) paper-cover structure (bit radial is arranged)

Graph milling cutter of 4.13 paper-cover structure

Paper-cover structure milling cutter (if the graph is shown 4.13 times) sex of craft of cutter hub structure is good, machine easily, can use the bit that do not have aperture (bit value is inferior, can grind) again. Because need clamping unit, the one part coverture of bit is built, the space that hold bit is lesser, and the hard alloy on cutting force direction is sectional and lesser, the milling cutter of reason paper-cover structure is used at commonly light-duty the quantity in mixing milling treatment.
2) establishs outfit structure (bit is tangential arrange)

Graph 4.14 establish outfit structure milling cutter

Establish outfit structure milling cutter (if the graph is shown 4.14 times) bit is secured with a bolt only go up in knife chamfer, the structure is simple, dislocation is convenient. Although cutting tool part is less, but the treatment difficulty of cutter hub is greater, need to undertake machining with 5 coordinate machining center commonly. Because bit uses cutting force clamp, clamping force increases along with the accretion of cutting force, accordingly but leave out clamping unit, increased look bits space. Because bit is tangential,install, the hard alloy in cutting force direction is sectional bigger, can undertake cutting cutting of deep, big feed greatly consequently, this kind of milling cutter is applied to heavy-duty the quantity in mixing milling treatment.
