New description: [New technical field] This creation department is about "improvement of cutting tool structure", especially a cutting tool with a tool head made of tungsten steel. · [Prior Art] . The continuous advancement of the tool field has provided a wide range of applications for the processing process. For the general purpose of the tool, it is divided into high-speed steels and cemented carbide. ) and other fields. However, because the idle speed steel tool is not wear-resistant and cannot be applied to high-speed cutting, it is based on the reasonable cost and the requirement of accuracy τ 'The high-axis tool has not been manufactured, and the carbon-junction type carbide (如义) Although it is more wear-resistant, the hardness can meet the requirements, but because the crane steel tools that are currently seen are replaced by the disposable blades, the discarded tungsten steel cutters are used for the first twist of the cutting. Still can't play a good help. • Therefore, if we can develop a ~* kind of body-formed turning tool head, 俾 effectively improve the cutting. Precision and voyage 'The city's tool head silk is resistant to impurities, and the secret is to improve the problem. Therefore, in view of this, the creator of this creator and his creative ideas have been designed with many years of experience. After many discussions and trials of sample tests, and many revisions and improvements, this creator was launched. [New Content] Technical Features for Solving the Problem: This creation provides a kind of _ tool structure improvement, and its _tool is made up of - the tool head is matched with the M352416 with the extension rod, and the towel and the cutter head are used to repair the hardness. The body is molded, and the outer circumference is made by grinding the new electric energy plus J1 to complete the smear and the micro-shaped chip flutes, so that the draining _ unremoved part can become -_, and the end secret corresponds to The center position of the tool head is finely reduced - slightly convex it! The dead point of the thief can be used to guide the center at _, and the cutter head is set to have a binding column in the different m system. Shape, and at the lower part of the outer rail section, the shaft of the rod is provided with a knot, and the joint hole is also stepped, and the inner 4 section is provided at the λΜ gift, thereby俾 俾 — - cutting tool structure improvement. Compared with the efficacy of the prior art: This creation knows: For the improvement of the cutting tool structure, the tool head is integrally formed by the mineral steel, so it is not only wear-resistant, but also can be considered on the high-speed butterfly. Precision and stability. [Embodiment] In order to make your review and euphemism more in-depth, understanding and understanding of the purpose of this office, and the ability of the sisters, please refer to the following [Examples of the drawings] for detailed explanation. First of all, please look at the first, second, third and fourth figures. The cutting tool (1) is made up of the - tool head (10) with the extension rod (10). The tool head (10) is integrally formed with tungsten steel of the same hardness, and the outer circumference is finished by grinding or electric discharge machining. The chip flutes (10) with the relative names of the cutting tops (11) and the - road m are used to make the (10) The outer unremoved portion may become a blade portion (13), and the end joint portion corresponding to the center position of the tool head (1〇) forms a slightly convex dead point (14), and the dead point (14) is utilized It can be used to guide the M352416 center during cutting. The tool head (1G) is reduced to the dead point (the end of the (4) is equipped with a binding column (15), and the binding column (15) is separated and recorded. The outer κ section (10) is provided, and the end of the shaft of the extension rod (10) is provided with a coupling hole (21), and the coupling hole (2) is also provided with a smaller diameter step. An internal thread section (22) persons. By the above structure 'in its actual use, it is directly inserted into the joint hole (8) by the joint column (10) and the external thread section (10) and the _ section (22) are screwed together (please also be shown by the fifth figure) In view of this, the extension rod (10) can be used to drive the cutter head (1〇) to rotate, and the integrally formed tungsten steel blade (13) can be used as a cutter on the surface of the workpiece. Moreover, the shaft of the extension rod (20) can also be made of the same hardness of the steel, and the coupling hole (8) and the internal thread section (22) can also be arranged at both ends of the shaft (please also show the sixth figure) On the two sides, there is a - tool head (10), so the job has a bilateral effect. / By the above specific structure, you can get the next benefit 4 knives q) is based on the Hegang Institute - the body surface is out, so it is not only resistant to impurities, but also depends on the high speed _, when _ can also have High precision and stability. In summary, this creation has indeed achieved a breakthrough structural design, and has improved creative content 'at the same time can achieve industrial use and progress, and this innovation is found in any publication, also novelty' In accordance with the provisions of the Patent Law_Articles, Sharp Law proposes a new type of patent application, and asks the fishing bureau review committee to grant legal patent rights. Only those who rely on the above, only Lin _ - 植 _, the material is limited to the creation of the real shape, the thief picking the lion material after the _ cut _ tilting, should still be covered by the scope of this creation patent. 7 M352416 [Simple description of the diagram] The first picture: is a three-dimensional combination of the creation.
