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. 4, propose the one three tooth wolfram steel milling cutter of the utility model one embodiment, comprise shank section 10, acutance portion 20 and cutter tooth portion 30; Described shank section 10 is cylinder, and described acutance portion 20 is frusto conical, and the large end face of frusto conical is connected with described cylindrical one end end face, and the large end face of frusto conical is equal with described cylindrical face area and coaxially arrange; Described cutter tooth portion 30 connects one end away from shank section 10, described acutance portion 20; Described cutter tooth portion 30 comprises cutter core 32 and three cutters tooth 31, described cutter core 32 is coaxially arranged with described acutance portion 20, the front end of described three cutters tooth 31 is evenly arranged on all sides of cutter core 32, and be spirally extended to the free end of cutter core 32, spiral angle is 45 degree, rotates in a circumferential direction 1/3rd weeks along cutter core.The three tooth wolfram steel milling cutters of the present embodiment, cutter core 32 and described acutance portion 20 are coaxially arranged, and can improve the precision of cutting, three cutters tooth 31 are evenly arranged in cutter core 32 circumference, and being spirally extended to the free end of cutter core 32, spiral angle is 45 degree, can improve the luminosity in cutting face greatly; Three tooth wolfram steel milling cutters of the present utility model, structure is simple, and cutting precision is high, cutting face height luminosity, and chip precision reaches 0.01 millimeter, is in industry-leading level.
In the present embodiment, above-mentioned shank section 10 diameter is 4 millimeters; The diameter of described cutter core 23 is 1.65 millimeters; It is 3 millimeters that cutter tooth 31 rotates along cutter core 32 axis the cylinder diameter produced.Milling cutter in the present embodiment, the dimensional fits of each parts, can carry out outward appearance chip polishing to chip material, and improve cutting precision and luminosity, chip precision reaches 0.01 millimeter, reaches industry-leading level.
In the present embodiment, the maximum length of chip of above-mentioned cutter tooth 31 is 8 millimeters, the maximum length namely participated in during 30 chip of cutter tooth portion.Can precisely cut the chip surface in 8 millimeters accurately, leading in the same industry of fineness.
