Description of the Invention: [Technical Field] The present invention relates to a chamfering machine, and more particularly to a chamfering cutter that utilizes a rotational force and can be coupled to a chamfering tool. [Prior Art] Chamfering (or beveling) refers to milling the edge of an object or the angle of a tool or engraving into a slant or circle, and the G device used to perform the chamfer is called chamfering. tool. Although there are different types of chamfering tools that perform chamfering in various ways, a representative practice is to use a chamfer cutter mounted at the end of a rotating shaft to rotate to perform chamfering. f When using such a chamfering tool At the time, the cutting debris (chips) generated by the rotational force may cause problems. If the cutting chips produced by chamfer cutting are long, these cutting chips may be entangled in the chamfering tool that rotates at a high speed, which is not conducive to the chamfering process. Even small cutting chips, if the ® cutting chips are not quickly removed, may increase the cutting load, which is not only difficult to continue the chamfering work, but also reduces the durability of the chamfering cutter. In order to solve the problem of cutting chips generated during chamfering, various prior art techniques have been developed, such as a method of forming a concave discharge in a chamfering cutter, but these efforts have not been particularly effective. SUMMARY OF THE INVENTION 201016357 The present invention has developed a chamfering cutter that solves the above problems in order to improve the efficiency in processing chamfering of cutting chips, thereby reducing the cutting load. A chamfer cutter according to the present invention can be coupled to a rotating shaft for rotating and trimming the edges of an object. The cutter has a central through hole. The cutter is coupled to one end of the rotating shaft by a fixing bolt inserted through the through hole; the cutter has a plurality of radial holes along the through hole一 a pure gear-like structure formed by the integrally formed cutting insert; the cutting insert has a shape protruding from a center, and each cutting insert includes a cutting insert portion and an arcuate portion, the cutting insert The part is formed at the end of the cutting blade in the direction of rotation, and the secret part forms a curved surface. And the cutting insert comprises a sharpening knife and an alternating rough grinding blade, which is _ Some have a button surface, and the thick (four) blade face has a rough surface. The advantage of the end Hi is in the arcuate portion connected to the cutting insert portion: Γ = a cutting chip breaking structure, and the cutting chip breaking structure has a double angle shape. Further, in the through-hole towel, there is formed a structure having a conical shape (four), and the crotch portion has a trapping position for the head end of the solid plug.

Figure 4 is a rear view showing the chamfer cutter of Figure 2. As shown in Figures 1 and 2, the chamfering machine of the embodiment of the present invention comprises a "through hole 1" in the middle, through which a rotating bolt can be inserted into the rotating shaft of the safety knife, and I can be inserted through the through hole. The bolt can be used to join the chamfering machine to the mrT 77', which can be a pure gear-like shape. It has a plurality of cutting inserts 2 that are radially surrounding. The number of cutting inserts 2〇 is in this embodiment. 6 slices...

It is decremented in the direction of rotation, so that the thickness opposite to the opposite of the lower blade is the thinnest. The cutting portion of the cutting blade of the cutting insert - the specific diameter of the cutting blade 20 with respect to the diametrical direction can be made into two types of knives according to the curved portion "' 4 3 〇, 4 〇 1 blade 40 two types, and the position of this 〇 4 可以 can be interchanged. Fine grinding blade 3 〇 201016357 has a smooth processing of the curved portion 34 to perform the refining operation 'and the coarse grinding blade 40 has The roughened curved portion 44. Fig. 5 is a cross-sectional view taken along line B-B' of Fig. 2. At the end of the curved portion 34 connected to the cutting insert portion 32, a cutting chip can be formed. A broken structure 36, which may be processed to have a double angled cross section. The cutting chip breaking structure 36 may form a smaller angle than the total cross section of the curved portion 34 at a portion joined to the cutting insert portion 32. This structural design of the cutting chip breaking structure 36 can reduce the size of the cutting chips during the chamfering operation, and can reduce the cutting load by about 30% because the cutting chips can be immediately removed. Fig. 6, showing the third Circle part of the picture "c "The view of the various possible shapes of the curved portion of the coarse sanding blade shown. The coarse sanding blade 40 has a plurality of different cross sections such as = these structures can be impractical when working in high precision such as fine grinding 'But it is possible to reduce the size of the cutting chips by chamfering, and the cutting load can be greatly reduced. Therefore, the roughing blade 4〇 is replaced by a chamfering machine with a fine grinding blade 3〇 having a cutting chip breaking structure 36, Compared with the normal chamfering cutter, it is possible to reduce the cutting load about _. Further, as shown in Fig. 3, the chamfering machine according to an embodiment of the present invention may include "the vertical raft 12 having a conical shape" having a diameter The tip end of the fixing bolt which is connected to the through hole 1G can be trapped in combination with the positioning of the fixing bolt which is connected to the through hole 1G. If the clamping portion 12 is designed as a conventional step structure, Then the tip end of the fixed thread inspection may not be connected to the clamp portion evenly (10), so when the bolt 201016357 使用 is used, the bolting force may not be reported, but a separate gasket may be required. However, according to the present invention, In the embodiment, if the tapered positioning portion 12 is used, it is ensured that the contact area with the bolt having a correspondingly shaped head end can be greatly improved, and the positioning force is also greatly increased. The above embodiment has been described. However, the above description is only for the preferred embodiment of the present invention, and those skilled in the art can make other improvements according to the above description, but these changes still belong to the creative spirit of the present invention and the following definitions.
