Description

Technical Field

[0001] This invention relates to the field of tool cutting technology, and more specifically, to a cutting and grinding disc. Background Technology

[0002] In modern industrial manufacturing, slicing discs are typically mounted on cutting machines. These cutting machines play a crucial role in industrial production, and slicing discs are key components, primarily used for cutting metal or plastic products. Grinding discs are often mounted on angle grinders. Angle grinders are common and practical industrial tools, and the grinding discs, powered by the angle grinder, are used to polish metal. Through continuous polishing, the originally rough metal surface gradually becomes smooth, thus meeting the industrial requirements for surface flatness and finish.

[0003] Under current technology, only the outermost part of the slicing layer is actually used for cutting. The slicing layer has a unique structure; the middle and inner rings are essentially substrate. During continuous cutting, the outermost ring constantly rubs against the material being cut, gradually wearing down over time. When the outermost ring of the slicing layer is almost completely worn away and can no longer perform effective cutting, the entire slicing layer is discarded according to current methods. However, this method has significant drawbacks because the discarded substrate portion still has some usability, resulting in a large waste of material. Similarly, the grinding discs used in angle grinders suffer from the same problem. During prolonged grinding, the functional parts of the grinding disc wear down, and when a certain point is reached, the entire grinding disc is discarded, again causing significant material waste. Utility Model Content

[0004] To address the problem of low utilization rate and significant material waste in existing technologies for slicing or grinding layers, this solution proposes a cutting and grinding method that manufactures the slicing and grinding layers as a single unit, allowing the grinding layer to replace the intermediate substrate layer of the slicing layer, thus solving the existing technical problems.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0006] This application provides a cutting and grinding disc, which is disc-shaped and includes...

[0007] A connecting layer having a mounting hole at its center for connection to the shaft of a cutting machine or angle grinder;

[0008] The grinding disc layer is connected to the outer periphery of the connecting layer and is made of a consumable material. As the grinding time increases, the outer diameter of the grinding disc layer will gradually decrease to the outer periphery of the connecting layer.

[0009] The slicing layer is integrally connected to the outer periphery of the grinding layer and is made of a consumable material. As the cutting time increases, the outer diameter of the slicing layer gradually decreases to the outer periphery of the grinding layer.

[0010] The cutting and grinding disc provided in this application has a connecting layer located at the innermost layer of the entire disc, a grinding layer connected to the outer periphery of the connecting layer, and a slicing layer located at the outer periphery of the grinding layer, forming the outermost ring of the disc. Both the slicing layer and the grinding layer are made of consumable material. In use, the cutting and grinding disc is first installed on a cutting machine until the slicing layer is worn down to the grinding layer. Then, the disc is removed from the cutting machine and installed on an angle grinder for continued use. When the grinding layer on the angle grinder is worn down to the connecting layer, the entire functional area of ​​the cutting and grinding disc is exhausted. Compared to traditional cutting machine slicing layers, the cutting and grinding disc provided in this application allows the slicing layer to replace the middle ring area of ​​the slicing layer. The slicing layer not only supports the slicing layer substrate but also allows for continued use up to the connecting layer. Therefore, it greatly improves the utilization rate of the slicing layer and avoids substrate waste.

[0011] Furthermore, in the slicing and grinding disc provided in this application, when the slicing layer is used, the slicing and grinding disc is connected to a cutting machine. The slicing layer can be directly used with the slicing and grinding disc on the cutting machine, enabling it to be manufactured into a standard model that is compatible with various cutting machines, without the need to specially manufacture cutting machines, which greatly improves the adaptability of the slicing and grinding disc.

[0012] Furthermore, in the cutting and grinding disc provided in this application, when the grinding disc layer is in use, the cutting and grinding disc is connected to an angle grinder. Once the cutting layer is worn away and the grinding disc layer is exposed, the cutting and grinding disc can be installed and used on the angle grinder. This eliminates the need to specially manufacture an adapted angle grinder, significantly improving the adaptability of the cutting and grinding disc.

[0013] In a cutting and grinding disc provided in this application, the thickness of the slicing layer is further less than the thickness of the grinding disc layer. A thinner slicing layer facilitates cutting, while a thicker grinding disc layer facilitates grinding. Furthermore, the thinning layer thickness being less than the grinding disc layer thickness allows for the formation of a boundary line between the slicing layer and the grinding disc layer, facilitating the observation of the wear allowance of the slicing layer.

[0014] Furthermore, in the slicing and grinding disc provided in this application, a glass fiber mesh is connected internally between the slicing layer and the grinding layer. The glass fiber mesh can effectively connect the slicing layer and the grinding layer, improve the strength of the slicing layer and the grinding layer, and prevent delamination due to the difference in density between the slicing layer and the grinding layer.

[0015] In a cutting and grinding disc provided in this application, the slicing layer further includes a smooth surface, and the grinding disc layer and the slicing layer are located on the same plane on the front or back surface of the smooth surface.

[0016] In a slicing and grinding disc provided in this application, the glass fiber mesh is further disposed on the side of the slicing layer and the grinding layer near the polished surface. Specifically, the glass fiber mesh is located at the center in the thickness direction of the slicing layer. The grinding layer and the slicing layer on the polished surface are on the same plane, which eliminates the step in the transition area between the grinding layer and the slicing layer. Disposing of the glass fiber mesh on the side near the polished surface allows the glass fiber mesh to remain flat and enhances the connection strength between the glass fiber mesh and the grinding layer and the slicing layer.

[0017] Furthermore, in the cutting and grinding disc provided in this application, the main component of the slicing layer is corundum or diamond. Using corundum and diamond as the main materials in the slicing layer effectively improves its hardness and strength, avoiding the risk of breakage due to its thinness.

[0018] Furthermore, in the grinding disc provided in this application, the main components of the wear material of the grinding disc layer are alumina and zirconia alumina. The main materials of the grinding disc layer are alumina and zirconia alumina, which can improve the strength of the grinding disc layer without affecting its functional requirements.

[0019] In the grinding disc provided in this application, the slicing layer has a thickness of 1.5mm to 3mm, and the grinding disc layer has a thickness of 5mm to 7mm. The thinner slicing layer (1.5mm to 3mm) reduces cutting resistance and material loss while maintaining cutting accuracy. The thicker grinding disc layer (5mm to 7mm) provides a larger grinding contact area and structural strength, ensuring grinding stability. Furthermore, the 5mm to 7mm thickness improves the rotational stability of the slicing layer and increases its strength, preventing breakage.

[0020] The slicing layer, with a thinner design of 1.5mm to 3mm, reduces cutting resistance and material waste while ensuring cutting accuracy. The grinding wheel layer, with a thicker design of 5mm to 7mm, provides a larger grinding contact area and stronger structural strength, ensuring grinding stability. Furthermore, the 5mm to 7mm thickness of the grinding wheel layer helps improve the rotational stability of the slicing layer, enhances its strength, and prevents breakage.

[0021] The beneficial effects of this application are:

[0022] This application provides a cutting and grinding disc with a connecting layer located at the innermost layer, a grinding layer connected to the outer periphery of the connecting layer, situated in the middle ring of the entire cutting and grinding disc, and a slicing layer connected to the outer periphery of the grinding layer, situated in the outermost ring of the entire cutting and grinding disc. Both the slicing layer and the grinding layer are made of consumable material. In use, the cutting and grinding disc is first installed on a cutting machine. When the slicing layer of the cutting and grinding disc is worn down to the grinding layer, the cutting and grinding disc is removed from the cutting machine and installed on an angle grinder for continued use. When the grinding layer on the angle grinder is worn down to the connecting layer, the entire functional area of ​​the cutting and grinding disc is worn out. Compared to the traditional cutting machine slicing layer, the cutting and grinding disc provided in this application can replace the middle ring area of ​​the slicing layer with a grinding layer. The grinding layer not only serves to support the substrate of the slicing layer but also allows it to be used continuously up to the connecting layer. Therefore, it can significantly improve the utilization rate of the cutting and grinding disc and avoid substrate waste. Attached Figure Description

[0033] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments.

[0034] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate for the embodiments of this application described herein.

Those skilled in the art can understand the specific meaning of these terms in this application according to the specific circumstances.

[0035] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments. Example 1

[0036] like Figures 1-4 As shown, this application provides a cutting and grinding disc, which is disc-shaped and includes a connecting layer 100, a grinding disc layer 200 and a slicing layer 300.

[0037] The connecting layer 100 has a mounting hole 110 at its center for connection to the shaft of a cutting machine or angle grinder. The grinding disc layer 200, made of a consumable material, is attached to the outer periphery of the connecting layer 100. As grinding time increases, the outer diameter of the grinding disc layer 200 gradually decreases to the outer periphery 120 of the connecting layer. The slicing layer 300, also made of a consumable material, is integrally attached to the outer periphery 210 of the grinding disc layer. As cutting time increases, the outer diameter of the slicing layer 300 gradually decreases to the outer periphery 210 of the grinding disc layer.

[0038] The connecting layer 100 of the cutting and grinding disc is located at the innermost layer of the entire cutting and grinding disc. The grinding disc layer 200 is connected to the outer periphery of the connecting layer 100 and is located in the middle ring of the entire cutting and grinding disc. The slicing layer 300 is located at the outer periphery of the grinding disc layer 200 and is located in the outermost ring of the entire cutting and grinding disc. Both the slicing layer 300 and the grinding disc layer 200 are made of consumable material. In use, the cutting and grinding disc is first installed on a cutting machine and used until the slicing layer 300 is worn down to the grinding disc layer 200. Then, the cutting and grinding disc is removed from the cutting machine and installed on an angle grinder for continued use. When the grinding disc layer 200 on the angle grinder is worn down to the connecting layer 100, the entire functional area of ​​the cutting and grinding disc is worn out.

[0039] The slicing and grinding disc provided in this application, compared to the traditional slicing layer of a cutting machine, can replace the middle ring area of ​​the slicing layer with a grinding disc layer. The grinding disc layer not only supports the substrate of the slicing layer but also allows it to be used continuously up to the connecting layer 100. Therefore, it can significantly improve the utilization rate of the slicing and grinding disc and avoid substrate waste. Compared to the traditional slicing layer of a cutting machine, the highlight of the slicing and grinding disc provided in this application is that the slicing layer has "zero residue," achieving 100% material application, while the residual amount of a traditional cutting disc is approximately 20%.

[0040] When using the slicing layer 300, the grinding disc is attached to the cutting machine. The grinding disc can be used directly on the cutting machine and is available in standard models, compatible with various cutting machines, eliminating the need to manufacture a dedicated cutting machine. This greatly improves the grinding disc's adaptability. Once the slicing layer 300 is worn down, the grinding disc can be attached to an angle grinder, using the grinding disc layer 200. After the slicing layer 300 is worn down and the grinding disc layer 200 is exposed, the grinding disc can be installed on the angle grinder for use, eliminating the need to manufacture a dedicated angle grinder. This again greatly improves the grinding disc's adaptability.

[0041] The thickness of the slicing layer 300 is less than that of the grinding layer 200. The thinner slicing layer 300 facilitates cutting operations, while the thicker grinding layer 200 facilitates grinding operations. In addition, the thinner slicing layer thickness creates a boundary between the slicing and grinding layers, making it easier to observe the wear allowance of the slicing layer.

[0042] A glass fiber mesh 500 is connected inside the slicing layer 300 and the grinding layer 200. The glass fiber mesh 500 can effectively connect the slicing layer 300 and the grinding layer 200, enhance the strength of the slicing layer 300 and the grinding layer 200, and prevent delamination due to the difference in density between the two.

[0043] The main components of the consumable material in the slicing layer 300 are corundum or diamond. Using corundum and diamond as the main materials in the slicing layer 300 effectively enhances its hardness and strength, avoiding the risk of breakage due to its thinness. The main components of the consumable material in the grinding layer 200 are alumina or zirconium corundum. Using alumina or zirconium corundum as the main material in the grinding layer 200 improves its strength without compromising its functional requirements.

[0044] The slicing layer 300 has a thickness of 1.5mm to 3mm. This thinner design (1.5mm - 3mm) reduces cutting resistance, minimizes material waste, and ensures cutting accuracy. The grinding layer 200, with a thickness of 5mm to 7mm, provides a larger grinding contact area and structural strength, ensuring grinding stability. Furthermore, the 5mm - 7mm thickness of the grinding layer 200 helps improve the rotational stability of the slicing layer 300, enhances its strength, and prevents breakage. Example 2

[0045] like Figures 3-4 As shown, the slicing layer 300 includes a smooth surface 400, and a grinding layer 200 and the slicing layer 300 are respectively disposed on the front or back of the smooth surface 400 and are located on the same plane. The back of the smooth surface faces the side of the cutting machine or angle grinder motor or motor shaft, and the front and back are opposite each other. A fiberglass mesh 500 is disposed inside the slicing layer 300 and the grinding layer 200, and is close to the side of the smooth surface 400. Specifically, the fiberglass mesh 500 is located at the center in the thickness direction of the slicing layer 300. The fact that the grinding layer 200 and the slicing layer 300 on the smooth surface 400 are located on the same plane ensures that there are no steps in the transition area between the grinding layer 200 and the slicing layer 300. The placement of the fiberglass mesh 500 close to the side of the smooth surface 400 also keeps the fiberglass mesh 500 flat and improves the connection strength between the fiberglass mesh 500 and the grinding layer 200 and the slicing layer 300.

[0046] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited to this. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
