Three lands are convexly equipped with along the length direction of the sword valve on the land of the two sword valves, three lands are arranged at intervals,
And divide into the first land, the second land and the 3rd land successively from front to back by cutting order；Wherein, first land
Projection highly less than the projection height of the second land, the projection of second land is highly less than the projection height of the 3rd land
Degree；
Wherein, several broached-tooth designs are provided with along respective bearing of trend on first land and second land；Described
Three lands extend along direction and are divided into leading portion and back segment, and direction is equally extended along on the leading portion of the 3rd land and is provided with several sawtooth
Structure, the back segment of the 3rd land then put the first edge on a knife or a pair of scissors processing；
Wherein, in the drill bit radially, the external profile diameter of the front end of each land is less than the external profile diameter of its rear end, structure
At least one cutting step is formed on into the drill bit along its length.
Relevant content in above-mentioned technical proposal is explained as follows：
1. in such scheme, first land is roughing sword, the second land is semifinishing sword, and the 3rd land is finishing
Sword；The design of three lands whereby, not only improves extension cutter life, is advantageous to be lifted the precision in processed hole and bright and clean again
Degree.
2. in such scheme, by the design of the broached-tooth design, it can make that land is sharper, and cutting resistance is small, Cutting free.
3. in such scheme, by the design of at least one cutting step, can further be lifted processing hole precision and
Finish.
4. in such scheme, the length of the sword valve is less than the length of the chip area, in order to chip removal.
5. in such scheme, the two sword valves are set in the shape of a spiral, form two chip areas and open up in the shape of a spiral, its spiral shell
Swing angle degree is less than 60 degree.
Can be whole hard alloy, or welding is hard 6. in such scheme, fluted drill of the present invention can be cold outside, can be interior cold
Matter alloy.
7. in such scheme, fluted drill of the present invention can be left-handed setting, or dextrorotation is set.
The operation principle and advantage of the present invention is as follows：
A kind of universal fluted drill of superfinishing of the present invention, including shank and drill bit；Drill bit is provided with two sword valves, is opened between two-edged valve
Provided with chip area；Three lands are convexly equipped with the land of two-edged valve, the first land, the second land are divided into successively by cutting order
And the 3rd land；The projection of first land is highly highly less than less than the projection height of the second land, the projection of the second land
The projection height of 3rd land；Several broached-tooth designs are equipped with first land and the second land；It is same on the leading portion of 3rd land
Sample is provided with several broached-tooth designs, and the back segment of the 3rd land puts the first edge on a knife or a pair of scissors processing；The front outer diameter of each land is less than rear end outer rim
Diameter, form and form at least one cutting step along its length on drill bit.
Compared to existing technologies, the present invention can process steel part and cast iron and the material of difficult machining kinds, and versatility is good,
Process hole precision superelevation, highly polished, and good processing stability, cutting-tool's used life length.
