New description: [New technical field] This is a kind of milling cutter structure, especially a joint milling cutter with the shank and the blade jointed together, and the joint is provided with the covering body to increase the joint strength. structure. [Prior Art] As the volume of various electronic products is gradually reduced, various parts manufacturing and processing processes inside electronic products are paying more and more attention to fineness, and the volume of printed circuit boards used for electronic component group setting = It is also necessary to use a micro-milling cutter to mill a groove on a printed circuit board when manufacturing a printed circuit board as the size of the electronic product is reduced. -The milling machine prints the electric red on the red part to make the tree, the scale is produced in the high-speed operation of the @温县 environment, the tool position in contact with the guard will be worn or even shy, so that the milling cutter can not Use, and then f replace the whole milling cutter, because the general sharp knife is made of carbonized n material, has good rigidity, hardness and long service life, but because of the high cost of carbonization, the whole domain knife is more advanced The manufacturing cost is greatly increased. In addition, under the realistic conditions of various negative sources of Wangqiu, the daily production capacity reduction of carbonized crane raw materials has led to a reduction in the cost of carbon scouring, which is a high cost for the milling and milling industry. Market Competitiveness. [New content] _ by the title of the 'Qing Qing's purpose - silk supply - difficult money knife structure, at the joint between the fixed surface of the shank and the knives, to strengthen the knives from the age of the small area In the milling process, the sharp cut-free and 14-to-break are eliminated, which has the advantages of reducing the cost of product manufacturing 3 and achieving the environmental protection effect of i, j:# source recycling. To achieve the above object, in the present invention, the knives of the embodiment, the octagonal end forms a fixed surface; the one edge portion includes a s-cut portion-end 1 connection (four) age (four)*. (4) and - the connecting portion is extended to the cutting and - ϊ / ίίί - the joining surface is joined to the fixing surface, and the covering portion covers a part of the outer surface of the connecting portion and the fixing surface and the connecting surface Joint. [Embodiment] The dry 2 Γ actual paid joint brain segment __, the joint diagram of the joint sharp knife structure shown in Fig. 2 is shown. As shown in Fig. 1, the joint 3 - (four) 12, the purchase 12 (four) spread - ® joint 121, handle. In the embodiment, the outer diameter of the handle 12 is 2 mm MmmM 3_175 male cover; the knife portion 14 includes a cutting portion 16 and a connecting portion 18, and the connecting portion 18 is extended. It is disposed at one end of the cutting material and a rear end of the connecting portion 18 forms a connecting surface 181, and the connecting surface (8) is engaged with the fixing surface (2) of the handle portion 12, as shown in FIG. 2, so that the handle portion! 2 and the blade portion 14 _ at the beginning; and the "cover body 2 (), the cover joint portion 18 the rear outer surface 182 (shown in Fig. 1) and the junction of the solid surface 121 and the joint surface (8). 1 and 2, wherein the shank portion 12 and the blade portion 14 are in the shape of a round rod, and the outer diameter of the flank portion 18 of the blade portion 14 is smaller than the diameter of the shank portion 12, so that the area of the joint surface (8) is smaller than the shank The area of the fixing surface 121 of the portion 12 is such that when the connecting surface 181 is engaged with the fixing surface 121 of the shank portion 12, the connecting surface 181 is joined to the central portion of the fixing surface 121 of the shank portion 12, and the fixing surface is fixed. The outer peripheral portion of the 121 is provided with a covering body 2 〇 to strengthen the joint strength between the connecting surface and the fixing surface 121 of the shank portion 12. Following the above description, in one embodiment, the material of the blade portion 14 is tungsten carbide, and the cutting portion 16 and the connecting portion 18 are integrally formed; the material of the shank portion 12 may be solid tungsten carbide or stainless steel shank portion 12 The connection surface 121 and the connection surface 181 of the connection portion 18 of the blade portion 14 are fixed together by solder heat welding or adhesive bonding. Furthermore, the material of the above-mentioned covering body 2 can be selected from solder or an adhesive. In one embodiment, the material of the covering body 20 is used for bonding the soldering surface 121 and the soldering surface used for the connecting surface (8) or The adhesive is the same, so that when the fixing surface (2) and the connecting surface 181 are joined by solder or an adhesive, the covering body 20 is simultaneously formed to cover the joint of the fixing surface 121 and the connecting surface (8). However, the material of the covering body 2G is different from the solder or adhesive used for the facing surface 121 and the joining surface. In the embodiment, the length of the blade portion 14 is between 3 and 2 inches, and the shank portion 12 is between 18 1 and 35 1; and the outer diameter of the cutting portion 16 of the blade portion 14 is specialized for Or smaller than the outer diameter of the connecting portion 1S, wherein the outer diameter of the cutting portion 10 is between Μ and 3 mm, and the outer diameter of the connecting portion 18 is between 〇·3 and 3 mm. In the present petal towel, the blade portion of the blade having a smaller diameter and a larger outer diameter is formed, and the joint is formed at the joint to increase the joint strength, because of the small outer portion and the knife portion. There is less carbonized niobium material to be used, so the material cost can be reduced. When using this sharp knife structure to process workpieces such as printed circuit boards, only the wear portion is used, and the handle of the outer diameter of the outer diameter is used. It does reduce the manufacturing cost of the product.
