New description: [New technical field] This creation is about the improvement of a discarded side milling insert, especially the rigidity of the cutting cutter, which can improve the cutting speed and service life. Small-sized side milling cutters or disposable side milling cutters with τ-shaped side milling cutters. [Prior Art] Generally used disposable side milling inserts, please refer to the seventh and eighth figures, mainly used in the large-size side milling cutter, the side-cut milling cutter 5〇, the discarded side milling cutter The inner cutting edge 52 of the 5G cutting surface 51 has an inwardly inclined inner cutting edge 52, and the inner cutting edge 52 forms a cutting edge with the upper plane 53 and the lower plane, respectively, and the cutting blade 55 has all the corner points. Please refer to the ninth figure, when the cutter is subjected to the cutting force F when cutting, 'Because the body volume behind the cutter 5S is small, the cutter tip is the most face-shaped, and it is very difficult to bear. Excessive cutting force, so the general-purpose side milling cutter 5〇 can only be used for large-size side milling cutters. There is no small-sized side milling cutter, and the small groove machining is only for small sizes. It can be processed by a body-formed Τ-shaped slot cutter, but the entire body-formed τ-shaped slot cutter is very expensive, so the processing cost is relatively increased. [New content] The disposable side milling cutters are used, and the body of the cutting side is small in volume, which is designed for the fragile structure. 'Lai can be applied to large-sized side milling cutters. The use of a slotted knife that is integrally formed and very expensive is relatively expensive to process. 3 and the creative side-cutting side milling cutter is composed of a polygonal body, the lower plane of the plane, the positioning surface of the trapezoidal shape and all the razor planes are formed. The cutting (four) upper and lower sides have (10) ribs _ Extending obliquely in the plane of the cutter-inner ride, the shaft-back bevel angle, and the outer edge of the (4) are provided with an arc shape and the angle between the edge of the phase and the (four) edge is made to form (4) all the blade angles α. The cutting angle α of the artificial side-cutting side milling cutter is increased, and the volume behind the cutting edge is increased, and the position of the cutting edge can be improved (4), thereby improving the cutting ability of the discarded side milling insert, the discarding side The diameter of the cutter can be reduced, and it can be applied to small-sized side milling cutters or τ-shaped side milling cutters. [Embodiment] Referring to the first to third figures, the artificial side-cutting side milling insert 10 is composed of a polygonal body having an upper plane u and a lower plane 12, and a trapezoidal positioning surface. 13 and all of the blade faces 14 are formed by the two sides of the blade body, and the two sides of the blade body are provided with a positioning taper hole 15 which penetrates the same, wherein the cutting edge surface 14 has a cutting edge 141 on the upper and lower sides. The cutting edge 141 faces the cutting face 14 The inner edge edge 142 ′ forms a rear bevel angle 0 ′ and an outer edge of the cutting edge 141 is provided with an arc-shaped outer edge 143 which is a radius r and the radius The size of R depends on the size of the blade body, whereby the angle between the outer edge 143 and the inner edge 142 causes the cutting edge 141 to form a full edge angle a. Referring to the third figure, the outer edge of the cutter 141 of the present invention forms an arc-shaped outer edge 143, so that the angle of the cutting edge angle α is increased, and the volume behind the boring tool 141 can be increased, and the volume is increased. The position is indicated by the slanting line A. According to this, the rigidity of the cutting object can be improved, and the cutter i4i is not easy to be cracked, so that it can be relatively raised, such as the speed cutting knife scale to improve the cutting ability, and the discarded side milling cutter 1G. The size is reduced, and it is suitable for small-sized side milling cutters. The radius R described above is formed in an arc shape on the outer edge of the cutter (4), and the outer edge 57 is also formed by a straight planar edge (4) instead of the arc, and the edge 143' still has the same effect. The angle of the cutter wire and the angle of the cutting edge increase the volume and rigidity of the cutter 141. Please refer to the figure shown in the fourth figure, which is used in the small side milling cutter 20 In the embodiment, although the size of the retractable side milling insert 1 is small, since the angle of the cutter angle α is increased and the volume behind the cutting edge 141 is increased, the rigidity of the (4) 141 can be improved, and the discarded side can be improved. The cutting ability of the iron blade 1,, the cutting diameter of the discarded side milling cutter can be reduced to about 10mm, which is the first structure of the discarded side milling cutter, which can not be applied to the traditional abandoned side sharpening blade. The technical bottleneck of the size side sharp knife, the small size side milling cutter 20 can be milled plane, side milling and sharpening of the groove; 凊 see the fifth figure, the original application is applied to the implementation of the small T-shaped slot cutter 30 Example 'The T-shaped slot cutter 30 can be used to mill a T-shaped slot, The cutting groove side, the groove bottom and the groove surface, and the milling of the half-moon keyway. Please refer to the sixth figure A, B, C, which is applied to the embodiment of the turning tool, and the front end of the turning tool 40 is provided with a knife seat. 41, the seat 41 can be locked to the M430331 abandoned side milling insert 10, and the turning tool 40 can be cut into the inner slot or the inner hole, and the use range is very wide. The outer edge of the cutting edge of the side milling cutter 77 forms the outer edge of the cutting edge, so that the cutting edge angle is increased, and the volume behind the cutting blade can be increased, and the cutting edge can be improved, thereby improving the cutting ability of the cutting tool. The design of the structure is the first of the tools. It can be applied in both milling cutter blades and turning inserts, and has the same effect. It can meet the requirements of patent application and apply for it according to law. [Simplified illustration] The second picture of the creation is the side view of the creation. The third picture is the side view of the creation. The fourth picture is the combination of the small size side milling cutter and the front view. Applied to small T-slots The combination of the knife and the front view The eighth figure A, Β, C The present application is applied to the embodiment of the turning tool.
