Description
Technical field
The present invention relates to a kind of fine helicon rose cutter, belong to field of machining.
Background technology
Along with the continuous development of micro-nano technology, Micrometer-Nanometer Processing Technology becomes current manufacturing industry one of active research focus the most as realizing its key technologies for application and important foundation.Exist the complex characteristic of the small-sized and meso-scale of a large amount of three-dimensionals (size between several microns to hundreds of microns) structure during at present industry is made; Requirement has high geometric accuracy and surface roughness; For these requirements, mechanical fine Milling Process has irreplaceable precision of other fine machining methods and flexibilities such as electrochemistry.In mechanical minuteness milling field; Micro-nano machining tool is succeeded in developing and commercialization in Germany, Japan and the U.S. etc.; But used milling cutter also is in the starting stage on these micro-nano machining tools; Generally be that large-scale cutter miniaturization is obtained; The defective that is had is following: the anterior angle of large-scale milling cutter generally be on the occasion of; Make the minuteness milling tool of miniaturization also have positive rake angle; Make that not only these minuteness milling tool rigidity are poor; And especially be not suitable for the microfabrication hard brittle material, be difficult to form smear metal and produce high-quality cutting surface; In the microminiaturized process of large-scale milling cutter, because the cutting edge feature affects, be difficult to miniaturization to 1 millimeter with interior radius of clean-up; The fine rose cutter that miniaturization gets is when the fine open complex-curved characteristic part that processing has that whole geometry characteristic integrality requires, and working (machining) efficiency is difficult to improve; The fine rose cutter that miniaturization gets owing to there is complicated geometric properties, makes that manufacturing efficient is low, and is difficult to obtain high-precision cutting edge during fabrication.
Research and development are suitable for the high rigidity of having of mechanical fine Milling Process, high accuracy and high efficiency small-sized milling cutter, and are for the innovative development that promotes milling cutter, particularly significant for the development that promotes the minuteness milling technology.
Summary of the invention
The object of the present invention is to provide a kind ofly can overcome above-mentioned defective, have high rigidity, high accuracy and high efficiency fine helicon rose cutter.Its technical scheme is:
A kind of fine helicon rose cutter; Constitute by cutter grip shank, cutting tip and the transition portion between cutter grip shank and cutting tip; Wherein be evenly equipped with a plurality of spheric helix cutting edges and a plurality of cone-type spiral side edge on the cutting tip; Each spheric helix cutting edge is smooth to connect a cone-type spiral side edge; The head end of a plurality of spheric helix cutting edges intersects at the summit of milling cutter; Between the adjacent two spheric helix cutting edges is the bulb knife face; Between the adjacent two cone-type spiral side edges is the side edge knife face; Promptly along the milling cutter direction of rotation; Cutting face behind the bulb of a spheric helix cutting edge; Be the preceding cutting face of bulb of next spheric helix cutting edge; It is characterized in that: each spheric helix cutting edge is negative value with the anterior angle α of the cone-type spiral side edge that is connected; And central angle β ＜ 85 of 60 °≤spheric helix cutting edge °; 0.05 the radius of clean-up of millimeter≤spheric helix cutting edge≤1 millimeter; Coning angle γ≤30 of 5 ° ＜ cone-type spiral side edge °; Bulb knife face and side edge knife face all adopt ruled surface, both smooth connections.
Described fine helicon rose cutter, the anterior angle α of spheric helix cutting edge and cone-type spiral side edge are all greater than negative 60 °.
Described fine helicon rose cutter is equipped with chip area on each bulb knife face.
The present invention compared with prior art, its advantage is:
1, because the anterior angle of each spheric helix cutting edge and cone-type spiral side edge is negative value; Make that the rigidity of minuteness milling tool is high; Help obtaining high dimensional accuracy; And in the fine Milling Process of machinery, help generating smear metal; When especially processing hard brittle material, help forming smear metal and generate high-quality cutting surface;
2,0.05 millimeter to 1 millimeter radius of clean-up is more suitable in the part processing with fine characteristic the present invention;
3, spheric helix cutting edge and cone-type spiral side edge make the present invention be more suitable for high efficiency, the high-quality processing in the fine open complex-curved characteristic part with the requirement of whole geometry characteristic integrality;
4, bulb knife face and side edge knife face all adopt ruled surface, make the present invention during fabrication, help obtaining to have the spheric helix cutting edge and the cone-type spiral side edge of high accuracy geometry, make efficient and also improve greatly.
