Abstract
Carbide end milling cutter with front wavelike cutting edge is that a kind of carbide alloy is the helical end mills of blade, is suitable for heavy cutting.This slotting cutter inlay or welding-on after the spiral tool section on cutter hub expansion, its rake face is a rippled surface, each tool section waveform staggers mutually, is different from the linear expanding surface of producing and using at present both at home and abroad.Its cutting load is steady, and vibrational energy is 54～83% of an ordinary rigid alloy helical end mills.The metal resection rate is 5～7 times.Rake face after the expansion is best with the sine surface.For strengthening point of a knife intensity, the cutter tooth front end does not possess waveform, and the point of a knife cutting edge inclination is 3～5 degree, and nose part has chamfering.
Description
Carbide end milling cutter with front wavelike cutting edge, be a kind of be the helical end mills of blade with the carbide alloy, be fit to heavy cutting.
Produce at present both at home and abroad and uses with the helical end mills of carbide alloy as blade, after its spiral tool section expansion, its rake face is linear, this helical end mills is when cutting, its cutting hardness is unbalanced, the cutter hub vibrations acutely.Damage carbide-tipped cutter bit easily, reduce service life.For fear of tool damage, must reduce cutting output, thereby efficient reduces.
Task of the present invention is to adopt a kind of novel tool section rake face, thereby avoids the inequality of cutting hardness, and the vibration when reducing to cut improves stock-removing efficiency and cutter life.
Carbide helical end mill, with the carbide alloy spiral bar inlay or welding-on on cutter hub, tool section have 15～30 the degree helical angles.After feature of the present invention was the expansion of this spiral tool section, rake face was a rippled surface, and each tool section waveform staggers mutually, and its dislocation equals the ratio of wavelength and cutter tooth number.
The present invention is owing to adopted the waveform sword face of mutual mistake, and its trough forms the chip dividing groove when cutting, and cutting load is steady, and the vibration when having reduced cutting has improved stock-removing efficiency and life-span.Through the cutting comparative test, its vibrational energy is 54%～83% of an ordinary rigid alloy slotting cutter, and the metal resection rate is 5～7 times of ordinary rigid alloy slotting cutter.
Fig. 1 is the expanded view of tool section of the present invention, its front 1 undulate.Fig. 2 is the expanded view of some cuttings, and its middle distance 2 is the corrugated dislocations of two adjacent cuttings, and 3,4,5,6 is the cutting edge that the cutter tooth front end does not possess waveform, and Fig. 3 is a side view of the present invention, and 7 is the nose part chamfering, and 8 is the point of a knife cutting edge inclination.
Rake face after the expansion of spiral tool section is best with the sine surface.
For strengthening point of a knife intensity, the point of a knife front end does not possess waveform, and its shortest tine length is got (0.8～1) individual wavelength, cutter nose part chamfering (0.8～1.5) * 45 degree, former to have cutting edge inclination be the point of a knife cutting edge inclinations that the local reconditioning of helical angle goes out 3～5 degree at point of a knife, and its length is 1～1.5 millimeter.
Claims (3)
1, carbide helical end mill, with carbide alloy spiral tool section inlay or welding-on on cutter hub, tool section has the helical angles of 15～30 degree, feature of the present invention is that this spiral tool section expansion back rake face is a rippled surface, each tool section waveform staggers mutually, and its dislocation equals the ratio of wavelength and cutter tooth number.
2,, it is characterized in that this spiral tool section expansion back rake face is a sine surface according to the carbide helical end mill of claim 1.
3, according to the carbide helical end mill of claim 1 or 2, it is characterized in that the cutter tooth front end does not possess waveform, its the shortest tine length is 0.8～1 wavelength, cutter nose part chamfering (0.8～1) * 45 degree, point of a knife is former, and to have cutting edge inclination be the point of a knife cutting edge inclinations that the local reconditioning of helical angle goes out 3～5 degree, and its length is 1～1.5 millimeter.
