However, with the diversification of processing requirements, the simple cutting function can no longer meet the needs of all scenarios.

[0003] Although traditional saw blades can achieve basic cutting functions, there are some defects in actual use. For example, in a Chinese patent with the publication number "CN 221291865 U", an impact-resistant die-pressed diamond saw blade is disclosed, including: a matrix; a plurality of connecting parts are arranged at the edge of the matrix, notches are arranged between the connecting parts, the connecting parts are connected with grinding teeth, the connecting parts have a plurality of branches, and each branch is provided with a through hole; further, the grinding teeth are fan-shaped and wrap the connecting parts; further, there is a gap between the grinding teeth; further, the connecting parts have at least three branches, and the branches have three convex corners; further, the notches are arc-shaped; further, the number of the grinding teeth is seven; when the saw blade is used, although it can cut materials, there is a certain probability that burrs exist on the cut surface after cutting the article, and an additional grinding step is required later, which increases the material processing steps and reduces the material processing efficiency. Content of the Utility Model

[0004] The utility model provides an efficient cutting and grinding blade to solve the problem that there is a certain probability that burrs exist on the cut surface after cutting an article with the existing saw blade, and an additional grinding step is required later, which increases the material processing steps.

[0005] To achieve the above purpose, the utility model provides the following technical solution: an efficient cutting and grinding blade, including a saw blade body, a plurality of cutting parts are formed at equal intervals in a circumferential array on the outer peripheral surface of the saw blade body, and a connecting hole is formed by inwards recessing at the axis center of the saw blade body;

[0006] A plurality of grinding layers are arranged on both sides of the saw blade body, the plurality of grinding layers contact from the edge position of the saw blade body towards the axis center of the saw blade body, and the plurality of grinding layers are distributed in a cyclone shape.

[0007] Preferably, a chip guiding groove is formed between adjacent two of the grinding layers.

[0008] Preferably, a plurality of heat dissipation grooves are formed at equal intervals in a circumferential array on the outer peripheral surface of the saw blade body, and the heat dissipation grooves are located between adjacent two of the cutting parts.

[0009] Preferably, convex teeth are convexly provided on both symmetric sides of the cutting part.

[0010] Preferably, a through positioning hole is provided on one side of the saw blade body, and the positioning hole is on one side of the connection hole.

[0011] Preferably, two anti-slip pads are symmetrically bonded on the saw blade body, and the connection hole is between the two anti-slip pads.

[0012] In the above technical solution, the technical effects and advantages provided by the present invention are as follows:

[0013] When the saw blade body cuts the material, the grinding layer is synchronously driven to rotate by the saw blade body, so that when the saw blade body cuts the material, the cut can be ground synchronously. When the cutting is completed by the personnel, the saw blade body will also complete the grinding of the cut synchronously, making the cut smoother, avoiding burrs on the cut surface generated by cutting, and eliminating the need for an additional grinding step in the later stage, reducing the material processing steps and improving the material processing efficiency.

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, but not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0020] Such as Figures 1 - 3As shown, an efficient cutting and grinding disc includes a saw blade body 1. A plurality of cutting parts 7 are formed at equal intervals in a circular array on the outer peripheral surface of the saw blade body 1, and a connection hole 2 for connecting the output shaft of the motor is recessed at the axis of the saw blade body 1;

[0021] A plurality of grinding layers 5 are provided on both sides of the saw blade body 1. The plurality of grinding layers 5 contact from the edge position of the saw blade body 1 towards the axis of the saw blade body 1, and the plurality of grinding layers 5 are distributed in a cyclone shape.

[0022] Through the above technical solution, when a person needs to perform a cutting operation, the saw blade body 1 is connected to the output shaft of the motor (not shown in the figure) through the connection hole 2, and the saw blade body 1 is fixed. After the saw blade body 1 is installed, the material to be cut is stably placed at the position to be cut, and the material is fixed. After the material is fixed, the cutting machine is pushed, and at the same time the motor is started, so that the motor drives the saw blade body 1 to rotate until the saw blade body 1 contacts the material. The cutting part 7 is driven to rotate by the rotation of the saw blade body 1, so that the cutting part 7 cuts the material. When the saw blade body 1 cuts the material, the saw blade body 1 will synchronously drive the grinding layer 5 to rotate, so that the grinding layer 5 grinds the cut surface of the material, making the cut surface of the material smoother and eliminating the need for subsequent grinding of the cut surface.

[0023] In addition, in the present utility model, when a person cuts a material through the saw blade body 1, since the grinding layer 5 is provided and the grinding layer 5 is made of CBN material or diamond material, the grinding layer 5 will grind the cut surface to generate grinding debris. In order to quickly discharge these grinding debris from the cut, as Figures 1 - 3 shown, a chip guiding groove 8 is formed between two adjacent grinding layers 5.

[0024] Through the above technical solution,

[0025] In addition, in the present utility model, since the saw blade body 1 cuts the material, a plurality of heat dissipation grooves 4 are formed at equal intervals in a circular array on the outer peripheral surface of the saw blade body 1, and the heat dissipation grooves 4 are located between two adjacent cutting parts 7.

[0026] In this embodiment, when the saw blade body 1 rotates to cut the material, through the cooperation of the heat dissipation grooves 4, the heat dissipation efficiency of the saw blade body 1 is improved, avoiding overheating of the saw blade body 1. In addition, when the saw blade body 1 cuts the material, the heat dissipation grooves 4 can guide the debris generated during the cutting of the material to be discharged faster.

[0027] And, when the cutting part 7 cuts the material, in order to reduce the resistance and reduce the vibration, as Figures 1 - 2 shown, convex teeth 6 are convexly provided on both sides symmetric to the cutting part 7.

[0028] In this embodiment, when the saw blade body 1 cuts the material, through the cooperation of the convex teeth 6, the vibration of the saw blade body 1 is reduced, and the stability of the saw blade body 1 when cutting the material is improved.

[0029] After the saw blade body 1 is installed, in order to make the saw blade body 1 more stable, as Figures 1 - 2 shown, a through positioning hole 3 is provided on one side of the saw blade body 1, and the positioning hole 3 is on one side of the connection hole 2.

[0030] In this embodiment, when a person installs the saw blade body 1, through the cooperation of the positioning hole 3 on the saw blade body 1, the saw blade body 1 is more firmly installed after installation.

[0031] Moreover, in order to further improve the stability of the saw blade body 1 after installation, as shown in the figure, two anti-slip pads 9 are symmetrically bonded on the saw blade body 1, and the connection hole 2 is between the two anti-slip pads 9.

[0032] In this embodiment, when the saw blade body 1 is fixed, through the cooperation of the anti-slip pads 9, the fastening of the saw blade body 1 after installation is further improved.

[0033] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
