The transition circle cambered surface of described cutting edge and wiper edges junction is R0.5mm ~ 1.0mm.
The cutting edge of described cutter head is on one side to be that starting point is provided with the wiper edges that the drift angle is α away from turning end points 1.0mm ~ 1.5mm place, and described drift angle α is 3 ° ~ 8 °.
The seamed edge horizontal sextant angle γ of described cutter hub is 8 ° ~ 12 °
Described cutter hub material is carbide alloy.
Fixedly the groove of cutter head employing welding is fixing on described cutter head and the cutter hub.
The beneficial effects of the utility model are:
1, cutter head of the present utility model is welded in the subtriangular groove of cutter hub cover access slot upper end, the cutter of this sandwich welding manner, and chip breaking is effective, and the fineness of work piece can arrive requirement, has saved finishing step one, has reduced production cost.
2, cutter head of the present utility model is welded in the groove, and groove plays positioning action during welding, has improved welding quality.
3, cutter head of the present utility model participates in the material employing polycrystalline diamond of cutting tip, other parts adopt carbide alloy, rationally utilize material, reduced the production cost of cutter, because hardness height, the wearability of polycrystalline diamond are good, improve the surface quality of work piece, prolonged the service life of cutter.
