Equipped with chip dividing groove, the chip dividing groove is communicated with the heat dissipation cavity in facing cutter, and the downside of each blade offers
The thermal vias being connected to heat dissipation cavity and chip dividing groove, the sword tooth of the blade and angle, that is, anterior angle of facing cutter radial line are 5-
10°。
More specifically, cylindrical mounting hole is provided with along axis in the middle part of the facing cutter, the mounting hole is in periphery
On be provided with keyway.
More specifically, the facing cutter and blade are made of high cobalt toughness high speed steel W 2Mo9Cr4VCo8.
More specifically, the blade is in semicircular arc structure along facing cutter radial line section.
More specifically, the number of the blade is 8.
More specifically, angle, that is, anterior angle of the sword tooth of the blade and facing cutter radial line is 7 °.
More specifically, the convex milling cutter includes that the facing cutter of multiple and different radiuses is laminated, each milling cutter
The outer ring of disk is provided with corresponding blade.
There are advantage and good effects for the utility model: the utility model is a kind of convex milling cutter, is set on facing cutter
Set chip dividing groove, heat dissipation cavity and thermal vias and be interconnected, air can enter from chip dividing groove when rotation, radiated cavity again from
Thermal vias discharge, the heat generated when working is taken away, be conducive to integral heat sink, avoid milling cutter temperature excessively high and cause in passing
There is the phenomenon that spring sword or crackle in strength reduction, improves the service life of milling cutter, and in addition the one of chip space is arranged in chip dividing groove
Side is simultaneously connected to, and the debris that milling generates can also be discharged from chip dividing groove, whole to have preferable chip removal performance；Furthermore open up a point bits
Slot, heat dissipation cavity and thermal vias can reduce material expenditure, lower expenditure cost；In addition the sword tooth of blade and facing cutter radial line
Angle, that is, anterior angle be 7 °, be 0 ° of milling cutter relative to anterior angle, cutting force can be reduced, blade is sharper, is conducive to improve cutting
Efficiency.
