', month 3, 5, new description: [New technical field] This creation relates to a milling cutter, especially a milling cutter for chamfering. [Prior Art] A milling cutter generally refers to a tool for drilling, and has a knife at its bottom end, and is moved downward by a milling cutter to drill a circular hole in the workpiece; and the chamfer is used for chamfering; The milling cutter further cuts a circular arc inclined surface whose outer diameter gradually increases from bottom to top at the periphery of the opening of the circular hole, so as to enlarge the peripheral edge of the opening of the circular hole, thereby removing the burr of the peripheral edge of the opening. In addition to the effect, it is more convenient for components such as bolts to enter the circular hole. The prior art milling cutter for chamfering comprises a mounting section and a cutting section which are connected up and down, and the mounting section is fixed to the machine table; the cutting section is used for cutting the workpiece, and the cutting section is an eccentric cone shape. And at least one cutting edge is disposed on the outer wall surface of the cutting section; when used, when the cutting edge of the cutting section contacts and cuts the hole wall of the circular hole ¥ 'Because the cutting section is eccentrically disposed, part of the cutting section also φ abuts In the hole wall, in addition to the step-by-step support to reduce the relative vibration of the milling cutter, the polishing effect can be achieved at the same time. However, the prior art milling cutter for chamfering has the following disadvantages: 1) In order to sharpen the cutter, the cutter often uses high-hardness materials such as high-speed steel and tungsten steel, but the materials are quite expensive and the prior art is sharp. The knife is integrally formed. Therefore, in addition to the entire cutting section, even the installation section also uses such expensive materials, which leads to an overall cost. 2. Even if the knife is made of high-hardness material such as tungsten steel, the blade is used for a long time. 3 M442206 It is inevitable that it will wear out after the replacement page is revised on October 3, 101. Since the milling cutter is integrated, it can only replace the whole one. Milling cutters, with other cutting sections that are not subject to wear and can still be used, part and installation sections must also be discarded together - resulting in unnecessary waste. 3 • The eccentric taper of the cutting section is more difficult to machine, which leads to a further increase in cost. [New content] In view of the above-mentioned prior art milling cutter for chamfering, the integral molding results in an overall costly and wasteful replacement, and the eccentric tapered shape is difficult to process, resulting in cost reduction. "Chamfering cutters can effectively solve the above shortcomings. In order to achieve the above-mentioned creative purposes, the technical means adopted in this creation is to design a milling cutter for chamfering, which comprises: a body comprising a connecting section and a cutting section, the cutting section is a circular vertebra And the cutting section is radially recessed to form at least one chip flute and at least two guiding grooves; at least one blade is detachably mounted in a corresponding chip flute of the body, and the outer side of the blade protrudes from The outer wall surface of the cutting section, and the blade protrudes from the side of the blade; the hardness of the material of the blade is higher than the hardness of the material of the body; at least two guiding columns are respectively disposed in the corresponding guiding grooves of the body. The outer side of the guiding column protrudes from the outer wall surface of the cutting section, and the thickness of the guide protruding from the outer wall surface of the cutting section is smaller than the thickness of the blade protruding from the outer wall surface of the cutting section. The guiding column is made of tungsten steel. In order to achieve the above-mentioned creative purposes, the present invention can also provide a sharp knife for chamfering, which comprises: a body comprising a connected segment and a cutting segment, cutting 4 • 曰 correcting the replacement page • cutting The segment is rounded, and the cutting section is radially recessed and formed with at least three guiding grooves; a chip flute and at least three blades respectively detachably mounted in corresponding flutes of the body, each The outer side of the blade protrudes from the outer wall surface of the cutting section and the side of the blade hole is a blade edge; the hardness of the material of the blade is higher than the hardness of the material of the body; the eve-guide column is respectively disposed on the corresponding guiding groove of the body The outer side of each of the guiding columns protrudes from the outer wall surface of the cutting section, and the thickness of the guiding column protruding from the outer wall surface of the cutting section is smaller than the thickness of the blade protruding from the outer wall surface of the cutting section. The guiding column is made of tungsten steel. The advantage of this creation is that the cutting section and the mounting section can be free of expensive materials such as tungsten steel by making the blade relatively detachable from the cutting section, thereby effectively reducing the cost; Detachable, so the blade can be replaced separately after wear, and the other parts of the creation do not have to be discarded. 'By the way', by setting the guide post on the cutting section, and the guide post protrudes from the outer surface of the cutting section, so when When the blade touches and cuts the hole wall, the guide column will simultaneously abut against the hole wall to reduce the relative vibration and polishing effect. Finally, the cutting segment itself is a simple cone shape to facilitate manufacturing and reduce cost. Further, the milling cutter for chamfering, wherein the guide post protrudes from the side of the outer wall surface of the cutting section in a circular arc shape; the blade and the cutting section are fixed by screwing. The replacement blade can be easily disassembled by screwing. Further, the sharpening knife for chamfering has a single chip flute and two guiding grooves; and has a single blade and two guiding columns. And the milling cutter for the chamfering, wherein the two guiding columns and the blade 5 M442206 can be arranged at equal intervals. Thereby, the two guiding columns and the three points of the blade can be more evenly contacted and supported on the wall of the hole to further reduce the relative vibration. Or, further, the sharp knife for chamfering, wherein the body may have three chip flutes and three guiding grooves; there are three knives > 5 and three guiding columns. Moreover, the milling cutter for chamfering, wherein the guiding jaw and the blade are arranged in a staggered arrangement, the three guiding columns are equally spaced, and the three blades are equally spaced. Thereby, the three guide posts and the three blades can be more evenly contacted and supported on the wall of the hole to further reduce the relative vibration. Further, the milling cutter for chamfering is provided with a cutting edge on opposite sides of the blade. This makes it possible to take advantage of the blades made of hard and expensive materials. Further, the milling cutter for chamfering, wherein the guiding column and the cutting section are welded and fixed; the blade is made of tungsten steel or high speed steel.

In the embodiment, the number of flutes 121 is one, and the guide bow j M442206, 曰The number of replacements ^ " = 122 is corrected to be two 'the guide groove 122 is a cylindrical groove and the guide groove 122 is disposed along the slope of the cutting segment 12. The blade 20 is detachably mounted on the chip flute (2) of the body 1G. The outer side of the blade 20 protrudes from the outer wall surface of the cutting section 12 and the side of the second side is the knife 21; the hardness of the material of the blade 2 is higher than that of the body. The hardness of the material of the Chuanchuan; in the present embodiment, the blade 2Q and the cutting section 12 are screwed together, and the opposite sides of the blade 2Q are provided with a knife 21, whereby when the knife 21 is worn out 'The blade 2 can be used instead: the knife 21' and then under the same blade 2 〇 volume, the knife 1 can be set and used twice to fill the blade 20 made of expensive material; The blade 2 is made of tungsten steel or high speed steel. The two guiding columns 30 are respectively disposed on the two guiding grooves 122 t of the main body 1 ′.
