New description: 【New technical field】 This creation provides a kind of milling cutter structure improvement, especially for milling and cutting of printed circuit board with stone-distorted tungsten material. The clamping strength increases the precision of the milling cutter, and the blade and the handle are separated and replaced after the cutting edge of the milling cutter is worn, so as to reduce the cost of replacing the sharp knife. [Prior Art] According to the trend of electronic products gradually moving towards light, thin, short and small, all kinds of electronic products are gradually shrinking, and the manufacturing and processing of various fresh parts of scorpion products (10) are relatively The finer the silk, and the printed circuit board with printed electricity, t, and electronic zero-H position must be provided in various electronic products. The volume of the printed circuit board must also shrink with the size of the electronic product, and the printed circuit board process In the middle, the micro-milling cutter is usually used to mill the groove of the circuit board. However, during the milling process, the milling cutter will be ground: 'While the finer (four) plus the reading industry's milling cutter wear rate will be higher, This has led to an increase in the number of replacement sharp knives, and the replacement of the milling knives has to be sensitive to the entire milling cutter, resulting in a significant increase in processing costs 'is quite uneconomical. Therefore, Shen Yiren Cao in the 9th year of the 19th year, 9 曰 η, r +, Ping December 31 曰 "Application of a new type of milling cutter for the circuit board" application and approved by the announcement, the announcement number 5 4 2 0 3 No. 3, Saki (4) into the milling shank of the carbon shovel (4) into a sharp knife, the shank of the knives is made of different materials f, then when the shell is replaced, the cutter can be replaced, to the labor The cost, but the money handle:, the knife to reduce the printed circuit board plus no handle (four) Ling _ shooting, when the processing is held by the central M297280 'because its strength is weak, easy to be in the milling process If the deformation phenomenon is affected and the accuracy is affected, and the stainless steel handle cannot be reused many times, how to solve the above problems and lack of use, that is, the creators of the case and the relevant manufacturers engaged in the industry are eager to study and improve the direction.

Through multi-party evaluation and examination, and through years of experience in the industry, through continuous trial and modification, he has designed a new patent for the improvement of the structure of the milling cutter. By. The main purpose of our work is to improve the structure of the milling cutter. The milling cutter is made up of a handle made of tungsten carbide and a blade. The cutter is made of _ material and passes through the characteristics of carbonized material for printing. When the board is milled and cut, the strength of the sharp knife can be increased, and the handle of the carbonized crane can be used in the field, which can achieve the purpose of low cost and long service life. The purpose of this creation is that the joint between the milling cutter shank and the milling cutter is provided with a connecting surface and the working joint surface. When the cutting end of the sharp knife portion is worn during the processing and milling of the printed circuit board , only need to replace the milling cutter edge, which can reduce the processing cost. [Embodiment] One of the figures is to achieve the above-mentioned purpose, the means and structure of the present invention, and the features and functions of the preferred embodiment of the present invention are as follows.曰Please refer to the first and second figures for the 'Three-dimensional appearance of the creation, = decomposition'. It can be clearly seen from the figure that the sharp knife of the creation consists of the handle and the knife 2, 1 The part 1 is made of tungsten carbide material f, and has a joint surface M297280 and the blade portion 2 is also made of tungsten carbide material, and the side is provided with a mating surface. A cutting end 22 is provided on the other side of the working abutting surface 21. When the above-mentioned structures are assembled, the connecting surface 1 of the handle 1 is provided for the pair of the blade portions 2 = 2 1 to be fixedly combined, thereby forming a milling cutter, and the cutter and the cutter can be thoroughly milled. In the case of Yu Li, if the knives 2 are cut _ 2, the __2 is separated from the shank 1 and replaced with the new knives 2, and then the mating surface 2 i of the new knives 2 is reattached to the connecting surface of the shank i u: It is made of 'when the machine is clamped by the machine during the machining process, it has better two-knife and is deformed by two parts and 1 force, and increases the precision of the milling cutter and the material of the edge wear 2 w $ ^本, and after the replacement, the cutting end 2 2 P2 can be recycled and reused after reprocessing to meet economic benefits. Welded joints (4) 1 joint surface 1 and turn 2 simple surface 2 1 , in addition to the use of fixed joints, can also be bonded with a strong adhesive. The structure of the sharp shank and the knives is only the preferred embodiment of the present invention, and p # :: and ― ^ In summary, the above-mentioned milling county 彳 ^ its efficacy and purpose, so the creation of this For the purpose of "practical use", the application requirements for the correctness can be met, and the application for the difference according to law 1 · 2: The hardship of the new patent person _, the age of the situation to hide ~ =, to protect the creator to do their best to cooperate, the real sense of virtue . 4 silk secret, creation M297280 [Simple description of the map] The first picture is the three-dimensional exploded view of the creation.
