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, roughing milling cutter opened by a kind of wolfram steel proposing the utility model one embodiment, comprises shank section 10 and cutter tooth portion, and both are coaxially arranged and one-body molded; The rear end that described cutter tooth portion comprises cutter core 23 and three cutters tooth, 21, three cutters tooth 21 is evenly arranged at cutter core 23 stiff end along cutter core 23 circumference, and is spirally extended to the free end of cutter core 23, and rotate in a circumferential direction 1/3rd weeks along cutter core 23, spiral angle is 38 degree; The back-off of described cutter tooth 21 arranges at least two chip-breakers arranged side by side.By arranging at least two chip-breakers arranged side by side on the back-off of cutter tooth 21, can improve chip breaking effect, thus improve the chip efficiency of large surplus, chip efficiency reaches leading level.
In the present embodiment, above-mentioned shank section 10 length is 55 millimeters; The diameter of described cutter core 23 is 13 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 20 millimeters.Milling cutter in the present embodiment, the dimensional fits of each parts, can carry out outward appearance chip polishing to the chip workpiece of large surplus, improves and cuts stock-removing efficiency.
In the present embodiment, the maximum length of chip of above-mentioned cutter tooth 21 is 20 millimeters, and namely cutter tooth portion participates in the maximum length of chip is 20 millimeters.Can carry out large surplus cutting to the incisal bevel in 20 millimeters accurately, chip surplus efficiency is high, and fineness reaches leading level.
In the present embodiment, the angle of the shaping relief angle 214 of described cutter tooth 21 is 10 degree.The angle of shaping relief angle is arranged, and can improve the precision of cutting product, high polishing degree and stock-removing efficiency, the angle of shaping relief angle 214 is 10 degree is a best angle, can improve stock-removing efficiency.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 21,211 angles are 9 degree, and after end tooth two, 212 angles are 16 degree; End tooth anterior angle 213 angle is 5 degree.After end tooth one 211 and end tooth two after angle set by 212, 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 213 is arranged, and both can provide enough sharpness, and can ensure again the rigidity of cutter tooth 21.
In the present embodiment, after described end tooth one, the width of 211 is 1.5 millimeters, reasonably can control cutter tooth 21 and the friction of processing work, improve stock-removing efficiency.
In the present embodiment, the free end of described cutter tooth 21 arranges chip pocket 22, can get rid of the waste material cut.
In the present embodiment, the bending place between the end of the free end of above-mentioned shank section 10 and side arranges chamfering 11, facilitates the clamping of shank section 10 and fixture, and prevents shank section 10 from hurting user.
The foregoing is only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
