Abstract
The cutting tool of the present invention has only one spiral groove and is suitable for drilling hole, reaming, fraising, milling slot and especially high precision machining and machining fragile metal. It has simple manufacture process and simple sharpening process without need of special grinding machine.
Description
One, technical field: the present invention is applicable to boring, reaming, fraising, groove milling, is particularly useful for the higher above-mentioned processing of required precision.
Two, background technology: fluted drill, reamer, slotting cutter, first quarter moon brill etc.
Three, summary of the invention:
1. cutter of the present invention includes single helical groove drill bit, reamer, reamer and single helical groove groove slotting cutter;
2. single helical groove cutter of the present invention is to develop on the basis of the contradiction between defective that analysis conventional multiple-cutting-edge (many helicla flutes) cutter exists and modern requirement on machining accuracy improve day by day;
3. cutter of the present invention is approximate with conventional tool in shape, and the structure of each funtion part is also similar.But the blade that has only a helicla flute on the cutter of the present invention and generated by it as the entity drill, generates an end sword of crossing the center by helicla flute.Outer round surface is the face of cylinder, no land.Reamer, reamer also generate an end sword of not crossing the center by helicla flute, and outer round surface is the face of cylinder, no land.Slotting cutter then generates an end sword and a cylinder sword that grinds along helicla flute of crossing the center by helicla flute;
4. entity drill of the present invention is because of its main cutting edge is crossed the center a little less than the center, so can eliminate zero velocity phenomenon in the machining.The unbearable extruding that has partly replaced conventional drill with cutting improves the cutting situation, reduces heat and takes place;
5. cutter of the present invention has very strong antijamming capability and good processing stability, as drill bit of the present invention, reamer, reamer is supporting with the treatment of surfaces of components all, and it is irregular farthest to have alleviated material, gives the adverse effect that hole shape position degree deviation etc. causes back processing.The aperture precision of boring is improved; Reaming, fraising not only improve aperture precision but also can improve the shaped position precision, and slotting cutter can be suppressed at cutting partially under the cutting force effect effectively, improve positional precision, and be particularly outstanding when the narrow groove of milling, deep trouth;
6. cutter of the present invention is because have only a helicla flute, so its cross-sectional area greater than similar multiple-cutting-edge (many helicla flutes) cutter, helps improving the intensity and the rigidity of cutter;
7. cutter of the present invention because have only a helicla flute, so it is made simply, grinds, grinds cutting edge of a knife or a sword and all be easier to.End sword as reamer, reamer can be stabbed mill to death, and the drill bit of entity boring can need not the target drill grinding machine with general tool sharpening mill;
8. cutter of the present invention is because have only a cutting edge, so its working (machining) efficiency not as multiple-cutting-edge (many helicla flutes) cutter height, when entity brill, drilling ductile metal, is divided bits, chip removal difficulty, so should be used for the processing of high processing of required precision and brittle metal.
Four, description of drawings:
1. Fig. 1 is the schematic perspective view that the single-screw slotted eye is used, groove is used cutter;
2. Fig. 2 is the angle and the shape of knife end sword.Can be various, different with service condition, the φ angle that Fig. 2 marked generally equals 60 °, and this is a kind of canonical form, and the angle of opposite side is the accumulated angle of φ angle and relief angle α, and it just forms naturally as long as φ and α determine the back, need not mark;
3. the present invention has only a helicla flute, and helicla flute passes through mutually with cutter master cylinder, go up to form breach at end face (plane, the conical surface etc.), and grinds suitable relief angle in the bottom of the rib of helicla flute direction of rotation one side, thereby generates cutting edge.Cutting edge can be higher or lower than bit central, but near the center, the sword height must be lower than center 0.01～0.03.The opposite side of helicla flute (breach), the intersection point of rib and cutting edge then must be positioned at the left side of initial point (0 point), promptly-and directions X.(see figure 2)
Five, the specific embodiment: the relief angle α of single-screw traverse drill, milling cutter, can adopt the not contour grinding method of emery wheel and bit central, on the sword total length, the numerical value of relief angle α equates, its anterior angle reduces to zero by the γ=θ at outer rim place gradually to the center, do not have big anterior angle and take place, so full sword all is in normal cutting state.
Claims (3)
1. the single-screw slotted eye is with, groove cutter, and its characteristic is: have only a helicla flute, all the other are similar to conventional tool.
Tool category:
1) single helical groove drill bit, reamer, reamer;
2) single helical groove slotting cutter.
2. single helical groove drill bit, reamer, the reamer described in claim 1, its technical characterictic are the end sword that has only a helicla flute and formed by this helicla flute, and outer round surface is the face of cylinder, no land;
3. the single helical groove slotting cutter described in claim 1, its technical characterictic are to have only a helicla flute and end sword that is formed by this helicla flute and the cylinder sword that grinds along this helicla flute.
