The realization of the utility model object, functional characteristics and advantage will in conjunction with the embodiments, are described further with reference to accompanying drawing.
Detailed description of the invention
Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
With reference to Fig. 1-Fig. 5, propose the one four tooth wolfram steel milling cutter of the utility model one embodiment, comprise shank section 10 and cutter tooth portion; Described shank section 10 is cylinder, and an end connects described cutter tooth portion; Described cutter tooth portion comprises cutter core 23 and four cutters tooth 21, described cutter core 23 is the cylinder that arranges coaxial with described shank section 10, the rear end of described four cutters tooth 21 is evenly arranged on the side face of cutter core 23, and is that the angle of 45 degree extends spirally one week along the side face of cutter core 23 to free end with spiral angle; It is identical with the diameter of described shank section 10 that described cutter tooth 21 rotates around cutter core 23 axis the cylindrical diameter formed.The four tooth wolfram steel milling cutters of the present embodiment, be provided with four cutters tooth 21, and spiral angle is 45 degree, cutter core 23 and described shank section 10 are coaxially arranged, can improve the precision of cutting, four cutters tooth 21 are symmetricly set on cutter core 23, and are spirally extended to the free end of cutter core 23, and along cutter core 23 spiral one week, the luminosity in cutting face can be improved greatly; Four tooth wolfram steel milling cutters of the present utility model, structure is simple, and cutting precision is high, cutting face height luminosity, solves the problem of cutting precision and cutting face luminosity in conventional art, reaches leading level.
In the present embodiment, the diameter of described cutter core 23 is 3.6 millimeters; The cylinder diameter that cutter tooth 21 rotates generation along cutter core 23 axis is identical with the diameter of described shank section 10, is 6 millimeters.Milling cutter in the present embodiment, the dimensional fits of each parts, can carry out outward appearance chip polishing to chip material, improves cutting precision and luminosity.
In the present embodiment, the maximum length of chip of above-mentioned cutter tooth 21 is 15 millimeters, refers to that cutter tooth portion participates in the maximum length of chip.Can precisely cut the chip surface in 15 millimeters accurately, fineness reaches top standard in the industry.
In the present embodiment, above-mentioned cutter tooth 21 shaping one after 211 angle be 9 degree, the angle of 212 is 25 degree after shaping two.The angle of shaping relief angle is arranged, and can improve the precision and high polishing degree of cutting product, after shaping one after 211 and shaping two the angle of 212 be respectively 9 degree and 12 degree be best angle.Shaping relief angle can reduce the area of cut of cutter tooth 21 and workpiece, and reduces and the surface of the work friction of having processed.
In the present embodiment, after the end tooth one of above-mentioned cutter tooth 21,213 angles are 8 degree, and after end tooth two, 214 angles are 16 degree; End tooth anterior angle 215 angle is 8 degree.After end tooth one 213 and end tooth two after angle set by 214, when ensureing cutting effect, reducing the chip area of cutter tooth 21 and workpiece, and reducing and the surface of the work friction of having processed.The angle of end tooth anterior angle 215 is arranged, and both can provide enough sharpness, and can ensure again the rigidity of cutter tooth 21.
In the present embodiment, after above-mentioned end tooth one, the width of 213 is 0.3 millimeter, reasonably can control the friction of cutter tooth 21 and processing work.
