Abstract
The invention relates to a superfine tapered ball end milling cutter. The superfine tapered ball end milling cutter is composed of a cutter clamping handle, a cutting part and a transitional part between the cutter clamping handle and the cutting part, wherein the cutting part is uniformly distributed with a plurality of arched cutting edges and a plurality of tapered side edges, each arched cutting edge is smoothly connected with one tapered side edge, head ends of the plurality of arched cutting edges intersect at the vertex of the milling cutter, a ball end cutter face is between two adjacent arched cutting edges, and a side edge cutter face is between two adjacent tapered side edges. The superfine tapered ball end milling cutter is characterized in that rake angles alpha of each arched cutting edge and each tapered side edge are both negative values; and the central angle beta of each arched cutting edge is not less than 60 degrees but less than 85 degrees, the cutting radius of the arched cutting edges is not less than 0.01 mm but not more than 1 mm, and a conical angle gamma of each tapered side edge is not less than 5 degrees but not more than 30 degrees; a ball end cutter face and aside edge cutter face are both ruled faces and are smoothly connected with each other. By adopting the superfine tapered ball end milling cutter, the preparation efficiency is high and the higher cutting edge geometric precision is easy to obtain. The superfine tapered ball end milling cutter is particularly suitable for finely cutting parts with complex curve feature.
Description
Technical field
The present invention relates to a kind of fine taper 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 is that large-scale cutter miniaturization is obtained, and 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; When the fine rose cutter that miniaturization gets had the extra high fine open complex-curved characteristic part of required precision in processing, working (machining) efficiency was 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 taper rose cutter.Its technical scheme is:
A kind of fine taper rose cutter; Be made up of cutter grip shank, cutting tip and the transition portion between cutter grip shank and cutting tip, wherein be evenly equipped with a plurality of circular-arc cutting edges and a plurality of taper side edge on the cutting tip, each circular-arc cutting edge is all smooth to connect a taper side edge; The head end of a plurality of circular-arc cutting edges intersects at the summit of milling cutter; Being the bulb knife face between the adjacent two circular-arc cutting edges, is the side edge knife face between the adjacent two taper side edges, promptly along the milling cutter direction of rotation; Cutting face behind the bulb of a circular-arc cutting edge; Be the preceding cutting face of bulb of next circular-arc cutting edge, it is characterized in that: the anterior angle α of each circular-arc cutting edge and taper side edge is negative value, and central angle β＜85 of 60 °≤circular-arc cutting edge °; 0.01 the radius of clean-up of millimeter≤circular-arc cutting edge≤1 millimeter, coning angle γ≤30 of 5 °≤taper side edge °; Bulb knife face and side edge knife face all adopt ruled surface, both smooth connections.
Described fine taper rose cutter, the anterior angle α of circular-arc cutting edge and taper side edge are all greater than negative 70 °.
Described fine taper 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 circular-arc cutting edge and taper 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;
2,0.01 millimeter to 1 millimeter radius of clean-up is more suitable in the part processing with fine characteristic the present invention;
3, circular-arc cutting edge and taper side edge, simple structure helps obtaining the high accuracy of manufacture, makes the present invention be more suitable in the minuteness milling processing with the extra high fine open complex-curved characteristic part of required precision;
4, forward and backward knife face of bulb and the forward and backward knife face of side edge all adopt ruled surface, make the present invention during fabrication, help obtaining to have the circular-arc cutting edge and the taper side edge of high accuracy geometry, make efficient and also improve greatly.
