In above-mentioned a kind of index lathe paring blade, described blade body comprises three cutting units, cutting unit described in three is all in blade two and locates the acute angle position that side is linked to be, have the protuberance of arc between two adjacent cutting units, the angle of described cutting unit is 80 °.
In above-mentioned a kind of index lathe paring blade, the groove relief angle of described chip-breaker is 20 °-40 °.By arranging the groove relief angle of chip-breaker, being convenient to volume bits when cutting and guiding chip-flowing.
In above-mentioned a kind of index lathe paring blade, in the middle part of described blade body, be provided with the positioning center hole run through.By arranging positioning center hole, be convenient to the clamping and positioning to this blade.
Compared with prior art, a kind of index lathe paring blade of the present utility model has the following advantages:
1, by arranging chip-breaker, the crimp radius that effectively can reduce chip can guide the flow direction of chip simultaneously, be conducive to the curling of chip and fracture and chip-flowing machined surface can be avoided, cause the winding to surface of the work and scuffing, be conducive to cooling fluid simultaneously and enter blade rake face, play good cooling effect;
2, the annular empty avoiding groove by the locating surface up and down of blade body is arranged, has contact surface and the stress surface of optimization when clamping, make blade in clamping and use procedure, have locating effect better, is convenient to clamping, the advantage that processing vibration is little;
3, blade is provided with cutting edge hook angle structure, wherein blade main cutting edge arranges the first above-mentioned anterior angle, make it have sharp cutting edge, the viscosity such as stainless steel, material that plasticity is larger can be excised efficiently, fast, friction can be reduced, reduce heat in metal cutting and improve workpiece surface quality, the second anterior angle wherein blade main cutting edge arranged possesses and reduces chip and blade frictional force and the advantage strengthening blade cutting edge intensity.
