(11) cooperate with knife bar faying face (12) groove, limitation is real around screw axially bored line rotary freedom and axially translated freedom degree
Existing blade and cutter hub position, and the indexable insert tip, throw away tip (3) connect with the fastening screw (5) of knife bar (9), the indexable insert tip, throw away tip
(3) cross structure constituted at the top of cutter hub is symmetrical about eccentric axial, and the blade and cutter hub inclination cooperate, the two faying face
Tangent plane and basal plane angle are equal with helical angle, and cutter bar of milling cutter (9) radius is R, and staggeredly sword radial spacing is 0.1-0.15
R, axial spacing depth are 0.08-0.1 R, and development length is 0.1-0.15 R.
Beneficial effects of the present invention
A kind of titanic alloy machining indexable rose cutter of sword that interlocks is provided, the milling cutter is non-intersecting in bulb position cutting edge, preceding
Knife face width is not zero, and no Milling Speed and milling width are zero point, can realize aclinal milling not generating bad machining condition
It cuts, improves the posture flexibility of complex parts processing milling cutter；Trapezoidal positioning convex platform is equipped with using indexable insert tip, throw away tip lower surface
Cooperate with knife bar faying face groove, limitation around screw axially bored line rotary freedom and axially translated freedom degree, realize blade with
Cutter hub positioning realizes Insert holders connection with fastening screw, and structure is simple, and bonded area is big, solid and reliable, reduces positioning surface knot
Close screw loosening phenomenon in not close caused position inaccurate or processing；Using indexable in serts, it is mounted on height
On fast steel knife body, the waste for causing entire carbide-tipped milling cutter because of tipping using monoblock type carbide-tipped milling cutter is avoided, is improved
Economy；Blade tilt installation, blade is the intersection of helicoid and spherical surface, and compared to no spiral angular cutter, Milling Force reduces, milling
Brisk, surface quality is good.
