For solving the problems of the technologies described above, the invention provides a kind of three sword forming cutters, it comprises integrated knife bar and cutter head, described cutter head is provided with the blade of three annular arrays centered by the central shaft of described knife bar, three described blades include main cutting edge and front cutting edge, described main cutting edge is the curve sword of indent, described curve sword by several radian gradual changes and successively mutually the indent arcuate blade section of inscribe form, described front cutting edge is the straight line Zhou Ren parallel with the central axis of described knife bar, axial one end of described cutter head is connected on described knife bar, the other end forms the fluted disc shape end face of three teeth, one end of described main cutting edge is crossing with described front cutting edge, the other end is crossing with the crown of described fluted disc shape end face, three described blades are formed with chip area each other, each described chip area is crossing with the 3rd rear knife face around forming by the rake face of two adjacent blades respectively.
Be preferable over: the anterior angle of described main cutting edge is that zero degree, the first relief angle are that 13 °-15 °, the second relief angle are 20 °-25 °; The first relief angle of front cutting edge is that 13 °-15 °, the second relief angle are 20 °-25 °.
Be preferable over: on the major first flank of the main cutting edge of each described blade, be provided with lanyard, and damping relief angle is 2 °-4 °.
Be preferable over: the cutting edge circle run-out tolerance value of described main cutting edge is less than 0.005mm.
Be preferable over: described rake face is plane, and described rake face surface finish, the surface roughness of described rake face is no more than 0.2 micron.
Be preferable over: the boundary line between the rake face of two adjacent described blades and the 3rd rear knife face forms the bottom land sideline of described chip area, the camber line that described bottom land sideline is indent, one end, described bottom land sideline is crossing with the roller seating space of described fluted disc shape end face, and the described bottom land sideline tangent line at intersection point place and the central axis of described knife bar crossing with the roller seating space of described fluted disc shape end face is parallel.
Be preferable over: the angle between rake face and the 3rd rear knife face of every two adjacent described blades is 80 °, and often the angle between rake face and the 3rd rear knife face of two adjacent described blades is rounding structure.
Be preferable over: end tooth first relief angle of described fluted disc shape end face is that 8 °-12 °, the second relief angle are 18 °-24 °.
Compared with prior art, the invention has the beneficial effects as follows:
One, adopt the main cutting edge of inner concave curve shape can meet the segmental arc face processing of whole product, thereby only need a cutter just can complete the operation that much knives just can complete, and adopt an overall segmental arc face surface accuracy that cutter is processed high, there is not the uneven of multiple segmental arc face amalgamations formation, saved follow-up finishing step;
Two, on the major first flank of main cutting edge, be provided with lanyard, and then can make working angles more steady, eliminated shake cutter phenomenon, and lanyard can also strengthen cutting edge strength, and product finished surface is carried out to smoothing effect;
Three, the trench bottom sideline of the imploded arcs wire of described chip area can effectively guide bits slag to discharge to surrounding, the angle rounding structure of bottom land can ensure that chip removal is smooth and easy has increased the structural strength of stage property when not blocking bits, and described rake face polishing is also conducive to smooth and easy chip removal.
