Abstract
The invention relates to the technical field of cutters and in particular relates to a two-edge taper ball end milling cutter. The two-edge taper ball end milling cutter comprises a cutter head and a cutter handle. The two-edge taper ball end milling cutter is characterized in that an annular groove and a rectangular groove are formed in the upper end of the cutter handle; the annual groove is communicated with the rectangular groove; the cutter head is conical; a positioning groove is formed in the spherical bottom part; two cutting edges are arranged on the spherical surface; the cutting edges are spiral upwards along with the conical surface; spiral chip removal grooves are formed below the cutting edges and provided with edging sides; the edging sides are provided with protrusion edges; an anti-interference step is arranged between the cutter head and the cutter handle; the anti-interference step is conical; a dovetail transition part is arranged between the anti-interference step and the spiral chip removal grooves; the cutter head is coated with a silicon coating. The two-edge taper ball end milling cutter provided by the invention has the advantages that taper holes can be conveniently machined, chip removal effect is good, the machining surface of the cutter is smooth and the cutter is prevented from resonating with a clamping device so as to prolong the service life of the cutter.
Description
Technical field
The present invention relates to a kind of cutting-tool engineering field, particularly relate to a kind of two sword taper ball head milling cutters.
Background technology
Now for milling tapered hole and with the milling cutter of the deep hole of tapering can milling mould steel, cast iron, carbon steel, steel alloy, tool steel and general iron material, it exists cutting swarf to be difficult for discharging and shaking excessive defect when carrying out machining, cutting swarf is through accumulating for a long time, will make the cutting ability ability of milling cutter decline, and the bite that makes milling cutter diminishes and shakes and becomes large, causes the reduction of the efficiency of milling.
Summary of the invention
The present invention, in order to overcome the deficiency of above-mentioned technical problem, provides a kind of processing tapered hole convenient, and chip removal is effective, and tool sharpening smooth surface prevents that cutter and clamping device from resonating, thereby improves two long sword taper ball head milling cutters of cutter life.
The technical scheme solving the problems of the technologies described above is as follows:
Two sword taper ball head milling cutters, comprise cutter head and handle of a knife, cutter head is arranged on handle of a knife lower end, cutter head is provided with cutting edge and helical flute, described handle of a knife upper end offers annular groove and rectangular recess, annular groove communicates with rectangular recess, described cutter head is conical, tapering is 10 °, cutter head bottom is spherical, the radius of sphere is 1.5mm, spherical bottom is provided with locating slot, sphere is provided with two cutting edges, cutting edge is with on conical surface screw, under cutting edge, be equipped with helical flute, helical flute is provided with limit clearly, clear limit is provided with ridge, between described cutter head and handle of a knife, be provided with anti-interference ladder, anti-interference ladder is conical, one end that diameter is little is connected with cutter head, one end that diameter is large is connected with handle of a knife, between anti-interference ladder and helical flute, be provided with dovetail transition part, on cutter head, be coated with silicon coating.
Between described spherical bottom two cutting edges, be provided with chip pocket, chip pocket is connected with the helical flute on circular cone.
Described cutter head bottom is 13.5mm to the distance at helical flute top.
Adopt such scheme, two sword taper ball head milling cutters, handle of a knife upper end offers annular groove and rectangular recess, annular groove communicates with rectangular recess, annular groove matches with clamping device with rectangular recess, prevented that the phenomenon of skidding and shaking from appearring in this milling cutter in use, cutter head is conical, tapering is 10 °, be conducive to process tapering groove and processing tapering deep hole, cutter head bottom is spherical, the radius of sphere is 1.5mm, spherical bottom is provided with locating slot, be convenient to location, under cutting edge, be equipped with helical flute, helical flute is provided with limit clearly, clear limit is provided with ridge, be convenient to chip removal, improve the surface smoothness of machined surface, ridge can cut off the smear metal of spiral, prevent that smear metal from rolling up milling cutter, be unfavorable for milling cutter work, on cutter head, be coated with silicon coating, improve waterproof and the corrosion resistant performance of milling cutter, improve the surface smoothness of milling cutter.
