Abstract
The invention discloses a method for improving the working stability of an end mill and a high-stability end mill; the number of the teeth of the end mill is manufactured into an even number, so that the end edges of the teeth are unequally distributed on the same circumstance even if the angles of the end edge of each tooth and the end edges of the teeth on both adjacent sides are different, and meanwhile, the spiral angles of a spiral groove of the circumferential edge of each tooth and the spiral grooves of teeth on both adjacent sides are unequal; and consequently, the working stability of the end mill can be improved. The invention not only has the advantages of good working stability, high working efficiency and good processing quality, but also has the advantages of simple structure, easiness in production and long service life.
Description
Technical field
the present invention relates to a kind of method and high stable slotting cutter that improves the slotting cutter job stability, belong to the slotting cutter manufacture technology field.
Background technology
are present; In the prior art, general all the cutter tooth of slotting cutter is made into odd number tooth or even number toothing by impartial angle distribution, the slotting cutter of this odd number tooth or even number toothing by impartial angle distribution is when processing work; Usually can take place clocklike to vibrate; The appearance of this vibration greatly reduces the stability of slotting cutter work, because the instability of existing slotting cutter service behaviour; Tend to reduce the quality of converted products, but also can reduce operating efficiency.Therefore, the result of use of existing slotting cutter still is not ideal enough.
Summary of the invention
the objective of the invention is, and a kind of method and high stable slotting cutter that improves the slotting cutter job stability is provided, stability and operating efficiency and crudy when improving slotting cutter work, thus overcome the deficiency of prior art.
technical scheme of the present invention is achieved in that a kind of method that improves the slotting cutter job stability of the present invention is; The quantity of the cutter tooth of slotting cutter is made into even number; The end sword that makes cutter tooth is distributed on the same circumference by five equilibrium not; Even the angle of the end sword of the end sword of each cutter tooth and adjacent both sides cutter tooth is inequality; Make the spiral fluted helical angle of Zhou Ren of spiral fluted helical angle and adjacent both sides cutter tooth of Zhou Ren of each cutter tooth unequal simultaneously, can improve the job stability of slotting cutter like this.
Of the present invention a kind of high stable slotting cutter that
make up according to the method described above does; This high stable slotting cutter comprises the slotting cutter that is provided with knife bar and cutter tooth; And on each cutter tooth, all be provided with end sword and Zhou Ren; The quantity of the cutter tooth of its slotting cutter is even number; And the end sword of cutter tooth is not distributed on the same circumference five equilibrium, and promptly the angle of the end sword of the end sword of each cutter tooth and adjacent both sides cutter tooth is inequality, and the spiral fluted helical angle of the Zhou Ren of the spiral fluted helical angle of the Zhou Ren of each cutter tooth and adjacent both sides cutter tooth is unequal simultaneously.
The quantity of the cutter tooth of
above-mentioned slotting cutter is 4, and the end sword of 4 cutters tooth is not distributed on the same circumference five equilibrium, and promptly the angle of the angle of the end sword of the end sword of each cutter tooth and adjacent both sides cutter tooth is 93.9 ° and 86.1 ° respectively.
The quantity of the cutter tooth of
above-mentioned slotting cutter is 4, and the angle difference of all sword spiral fluted helical angles of per two adjacent cutters tooth of slotting cutter is: ∣ 1 °～10 ° ∣.
are owing to adopted technique scheme; The present invention is made into even number with the quantity of the cutter tooth of slotting cutter; And the end sword of cutter tooth is distributed on the same circumference by five equilibrium not, even the angle of the end sword of the end sword of each cutter tooth and adjacent both sides cutter tooth is inequality, can make the irregular distribution of effective cutting point (promptly putting cutting force) like this; Thereby centrality, the order of disperseing cutting force; Avoid clocklike periodic cutting force vibration, improved the stability and the stationarity of Milling Process greatly, improved working (machining) efficiency and crudy.The present invention simultaneously makes the spiral fluted helical angle of Zhou Ren of spiral fluted helical angle and adjacent both sides cutter tooth of Zhou Ren of each cutter tooth unequal; Thereby make the helicla flute spacing (or tooth pitch) of Zhou Ren of Zhou Ren and adjacent both sides cutter tooth of each cutter tooth unequal; The present invention adopts this helicla flute spacing inequality (or different tooth pitches) structure; Can produce an out of phase (out-phase) thus cutting movement stop the generation of resonance; Can effectively contain the vibration of cutter, improve processing fineness greatly, and increase the cutting depth and the feed speed of cutter.So, the present invention compared with prior art, the present invention not only has the good advantage of good operating stability, high efficiency and crudy, but also have simple in structure, produce easily, the advantage of long service life.
