1be 10 °-20 ° and ensure that side edge is not only sharp but also have enough intensity.The slotting cutter of this structure had both had longer face cutting edge, had again chip breaking function, applied widely, and cutting edge is not only sharp but also have enough intensity.
Preferred embodiment of the present utility model, the end-beveling β of described vertical milling handle of a knife is 20 ° to 30 °, facilitates slotting cutter to load chuck.
Preferred embodiment of the present utility model, the end of described milling cutter shank and vertical milling cutter hub is respectively arranged with centre bore, facilitates slotting cutter reconditioning.
Preferred embodiment of the present utility model, described side edge is 2-6 root, and helicla flute is 2-6 root.2-6 root side edge, 2-6 root helicla flute is both convenient to be cut, and facilitates chip removal again, can also ensure the intensity of slotting cutter.
Preferred embodiment of the present utility model, the anterior angle α of described side edge
1it is 15 °-18 °.This scope can ensure that side edge is not only sharp but also have enough intensity.
Preferred embodiment of the present utility model, the anterior angle α outside the sword of described outer face
2it is 25 °-30 °.This scope can ensure that the helicla flute of slotting cutter has suitable helical angle, facilitates chip removal, can ensure that again outer face cutlery has enough intensity
Preferred embodiment of the present utility model, the anterior angle α of described inner face sword
3it is 15 °-18 °.This scope can ensure that inner face sword is not only sharp but also have enough intensity.
