New description: [New technical field] This creation is a grinding wheel structure, in which the grinding wheel has a first abrasive layer which can trim the bottom edge and a sharp corner of the second abrasive layer. The characteristics of the blade, which can be trimmed for various blade angle changes of the milling cutter or the drill tool, and it has excellent convenience and operability. [Prior Art] "Working with good tools must first sharpen its tools", cutting with sharp drills or milling cutters, not only saves time and effort, but also easier to control accuracy, but even the sharpest drill or milling cutter, It will gradually become pure under continuous use, so the edge of the drill or milling cutter must be trimmed with a grinding wheel to maintain the optimum sharpness of the drill or milling cutter at all times. Nowadays, the grinding wheel system is driven by a motor and rotates around a center. The grinding wheel has a cutting end surface perpendicular to the center and a cutting circumferential surface which is rotated around the center at an equal distance. The user can use the cutting end surface and the cutting circumferential surface according to his own habits. The cutting edge of the drill bit or the milling cutter is generally not too difficult to trim the cutting edge of the drill bit or the milling cutter. The biggest difficulty lies in trimming the circumferential cutter of the drill or the milling cutter because the circumferential cutting edge Most of them are arranged along a spiral flute, and a circumferential relief angle and a radial clearance angle are formed between the circumferential cutting edge and the chip flute. Therefore, the chasing angle must be ground to correct the circumferential cutting edge, but nowadays The angle of the M324563 between the end face of the grinding wheel and the circumference of the grinding wheel is ninety degrees. It is difficult to insert and trim the angle of the clearance along the chip flute, which makes the circumferential blade unable to be smoothly and effectively trimmed, so that the drill bit or the milling cutter cannot maintain the best sharpness. status. In view of the fact that the existing grinding wheel cannot effectively trim the circumferential edge of the drill bit or the milling cutter, the creator is actively researching and trialing, and finally has the creation of this creation. [New content] Φ This creation department provides a grinding wheel that can effectively trim the circumference of the drill or milling cutter to keep the drill or milling cutter in the best sharp state. In order to achieve this, it was achieved with the following technology. The grinding wheel is provided with a first abrasive layer on the end surface of the core, and the core has a first abrasive layer, and then controls the angle between the ten-cut end surface and the cut peripheral surface of the first abrasive layer to be ninety degrees. For providing a trimming cutter or a lower end knife 37 respectively, the second abrasive layer has a cutting end face and a cutting conical surface, and (4) an acute angle portion of the axis less than ninety degrees, the acute angle portion can be inserted The milling cutter or the drill chip flutes trim the clearance angle of the circumferential cutter, so that the inventive grinding wheel has the convenience of grinding the milling cutter or the drill bit in all directions. In addition, the first abrasive layer has a coarser grain size than the first abrasive layer, so that the rounded surface and the acute angle portion can quickly trim the bottom edge, the angle, and the surface angle of the relief angle meets the requirements. In order to enable the review board to further understand the structure, features and other purposes of this creation, _ will be described in detail in the drawings of the preferred embodiment as follows. · M324563 [Embodiment] Please refer to the first to fifth figures, the creation of the grinding wheel The system includes: a core (10), please cooperate with the fifth figure, which has a center of rotation, the center is provided with a middle hole (1 1) for driving the shaft to rotate around the center, the core ( 1 〇) has two vertical center end faces (1 2 ) (丄3 ), one end face (1 2) and an outer circumference are recessed with an annular shoulder (14), and the core (10) outer circumference is shouldered The portion (14) forms a tapered conical surface (15) toward the other end surface (13); the first abrasive layer (20), together with the first and fifth views, is fixed to the shoulder (1) 4), forming a cutting end surface (2 1 ) that is aligned with the core (1 〇) end surface (; [2), and a cutting circumferential surface (2 2 ) of the outer circumference of the protruding shoulder (14), the first The angle between the cutting end face (2 1 ) of the abrasive layer (2 0 ) and the cutting circumferential surface (2 2) is 90 degrees, which can be used to provide the trimming cutter or the bottom end of the drill bit according to the user's habit. The cutting circumferential surface (22) is recessed at a position opposite to the other end surface (13) of the core (1) to form a notch (23) for abutting the second abrasive layer (30); The abrasive layer (30), please match the first and fifth diagrams, and the corresponding one is fixed on the conical surface (1 5 )' to form the end face of the core (1 〇) and the other ^1 3) a cutting end face (3 1 ), a cutting conical surface (3 2 ) rotatable around the center, and an acute angle of less than ninety degrees between the cutting end face (31) and the cutting conical surface (32) Part (3 3 ), the acute angle portion (3 3) can be inserted into the milling cutter or the drill flute to trim the relief angle of the circumferential cutting edge, and the M324563 is designed to make the scale grinding wheel have the convenience of grinding the milling cutter or the drill bit in all directions. . In addition, the particle size of the second abrasive layer (30) is controlled to be thicker than the first abrasive layer (2Q), so that the tapered surface (3 2 ) can provide a milling cutter or a rough bottom edge. For grinding, the circumferential surface (2 2 ) of the first abrasive layer (2 〇) can be used for fine (fine) grinding; and the acute angle (3 3) can quickly trim the relief angle. Let the angle of the grind angle be as desired. In summary, the overall structure of the creation completely breaks through the shortcomings of the reformed conventional structure, so that the sharp corners of the artificial grinding wheel (3 3) can accurately and smoothly trim the clearance angle of the milling cutter or the drill bit, and these The structural features are not found in the same kind of products at all, so they are novel and progressive, and should meet the requirements of the new patent application. However, the above is only a preferred embodiment of the present invention. When it is not possible to limit the scope of the creation of the creation, that is, the equal change and modification of the patent application scope of the creation should still belong to the creation.
