Technical Field

[0001] This utility model relates to the field of composite grinding wheel technology, specifically a superhard abrasive composite grinding wheel with heat dissipation holes. Background Technology

[0002] Composite grinding wheels are grinding wheels composed of two or more different materials, typically including a base material and one or more additive materials. This design aims to combine the advantages of different materials to improve the performance of the grinding wheel. The main components of superhard abrasive composite grinding wheels are synthetic diamond or cubic boron nitride. These materials have extremely high hardness and can maintain stable performance under high-speed cutting and heavy-load conditions, making them suitable for machining high-hardness materials such as ceramics, glass, and stone. In addition, superhard abrasive composite grinding wheels also have high thermal and chemical stability, enabling them to work for extended periods in high-temperature and corrosive environments. Superhard abrasive composite grinding wheels are widely used in various high-precision machining fields, including precision grinding, ultra-precision turning, and high-speed cutting. However, existing superhard abrasive composite grinding wheels still have the following shortcomings:

[0003] When using existing superhard abrasive composite grinding wheels, a large amount of heat is generated after prolonged friction with the workpiece, which cannot be dissipated in time. This affects the service life and working efficiency of the grinding wheel, resulting in a decrease in the practicality and efficiency of the superhard abrasive composite grinding wheel. Utility Model Content

[0004] The purpose of this invention is to provide a superhard abrasive composite grinding wheel with heat dissipation holes to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a superhard abrasive composite grinding wheel with heat dissipation holes, comprising a grinding wheel disc, conical heat dissipation holes, and heat dissipation grooves. An mounting component is provided inside the grinding wheel disc, and a threaded mounting groove is provided inside the mounting component. An abrasive layer is provided in the middle of the grinding wheel disc, and a conical heat dissipation hole is provided on the outer side of the abrasive layer. A heat dissipation groove is provided at the rear end of the conical heat dissipation hole. A first glass fiber layer is provided on both sides of the outer surface of the abrasive layer, and a zirconium corundum layer is provided outside the first glass fiber layer. A second glass fiber layer is provided outside the zirconium corundum layer, and a diamond grinding layer is provided at the upper end of the second glass fiber layer.

[0006] Furthermore, the internal dimensions of the grinding wheel are adapted to the external dimensions of the mounting component, and the mounting component and the grinding wheel are embedded in each other.

[0007] Furthermore, the number of threaded mounting grooves is set to six, and the six threaded mounting grooves are equidistantly distributed inside the mounting component.

[0008] Furthermore, the conical heat dissipation holes are distributed perpendicularly to the heat dissipation grooves, and the diameter of the conical heat dissipation holes decreases from the outside to the inside.

[0009] Furthermore, the number of the conical heat dissipation holes is eight, and the eight conical heat dissipation holes are equidistantly distributed in the middle of the abrasive layer.

[0010] Furthermore, there are two first glass fiber layers, and the two first glass fiber layers are symmetrically arranged on both sides of the outer side of the abrasive layer with respect to the side center axis of the abrasive layer.

[0011] Furthermore, the outer side of the first glass fiber layer and the outer side of the zirconium corundum layer are horizontally distributed, and the upper surface of the first glass fiber layer and the lower surface of the zirconium corundum layer are closely attached.

[0012] Furthermore, a diamond grinding layer and a zirconium corundum layer are respectively disposed on the upper and lower sides of the second glass fiber layer, and the second glass fiber layer is disposed and confined between the diamond grinding layer and the zirconium corundum layer.

[0013] This invention provides a superhard abrasive composite grinding wheel with heat dissipation holes, which has the following beneficial effects:

[0014] 1. This utility model, through the setting of conical heat dissipation holes, can enhance air convection and reduce grinding temperature when using superhard abrasive composite grinding wheels with heat dissipation holes. This is achieved by using conical heat dissipation holes in the middle of the outer surface of the abrasive layer, thereby reducing thermal damage to the workpiece. At the same time, the heat generated during the rotation of the grinding wheel is quickly discharged through the heat dissipation grooves in conjunction with the conical heat dissipation holes, and the material waste is prevented from entering the grinding wheel, thus extending the service life of the superhard abrasive composite grinding wheel and improving the overall practicality and efficiency of the superhard abrasive composite grinding wheel.

[0015] 2. This utility model, through the setting of the zirconium corundum layer, enables the bonding between the zirconium corundum layer and the abrasive layer through the mesh-like first glass fiber layer when using a superhard abrasive composite grinding wheel with heat dissipation holes. This prevents the abrasive material from flying out after the grinding wheel breaks. At the same time, the zirconium corundum layer significantly improves the hardness and wear resistance of the grinding wheel, enhancing its compressive strength and anti-abrasion ability. The diamond grinding layer is fixedly installed on the outside of the zirconium corundum layer using the second glass fiber layer. The diamond grinding layer is the core part of the grinding wheel responsible for grinding. The high wear resistance of diamond results in less wear during the use of the grinding wheel, extending the service life of the grinding wheel and improving the overall practicality and efficiency of the superhard abrasive composite grinding wheel.

[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0021] like Figures 1 to 3 As shown, a superhard abrasive composite grinding wheel with heat dissipation holes includes a grinding wheel disc 1, conical heat dissipation holes 5, and heat dissipation grooves 6. A mounting component 2 is disposed inside the grinding wheel disc 1, and a threaded mounting groove 3 is formed inside the mounting component 2. An abrasive layer 4 is disposed in the middle of the grinding wheel disc 1, and conical heat dissipation holes 5 are formed on the outer side of the abrasive layer 4. A heat dissipation groove 6 is formed at the rear end of the conical heat dissipation holes 5. The internal dimensions of the grinding wheel disc 1 are adapted to the external dimensions of the mounting component 2, and the mounting component 2 is embedded in the grinding wheel disc 1. Six threaded mounting grooves 3 are provided, and the six threaded mounting grooves 3 are equidistantly distributed inside the mounting component 2. The conical heat dissipation holes 5 and the heat dissipation grooves 6 are perpendicular to each other. The conical heat dissipation holes 5 are distributed in a way that the diameter decreases from the outside to the inside. There are eight conical heat dissipation holes 5, which are equidistantly distributed in the middle of the abrasive layer 4. The conical heat dissipation holes 5 in the middle of the outer side of the abrasive layer 4 enhance air convection, reduce grinding temperature, and thus reduce thermal damage to the workpiece. At the same time, the rear end of the conical heat dissipation holes 5 is connected to the heat dissipation groove 6. The heat dissipation groove 6, together with the conical heat dissipation holes 5, quickly dissipates the heat generated during the rotation of the grinding wheel disk 1, while preventing material debris from entering the grinding wheel, extending the service life of the superhard abrasive composite grinding wheel, and improving the overall practicality and efficiency of the superhard abrasive composite grinding wheel.

[0022] like Figures 1 to 3As shown, a first glass fiber layer 7 is disposed on both sides of the outer surface of the abrasive layer 4, and a zirconium corundum layer 8 is disposed outside the first glass fiber layer 7. A second glass fiber layer 9 is disposed outside the zirconium corundum layer 8, and a diamond grinding layer 10 is disposed on the upper end of the second glass fiber layer 9. There are two first glass fiber layers 7, which are symmetrically arranged on both sides of the outer surface of the abrasive layer 4 about the central axis of the side surface of the abrasive layer 4. The outer surfaces of the first glass fiber layers 7 and the zirconium corundum layer 8 are horizontally distributed, and the upper surface of the first glass fiber layer 7 is in close contact with the lower surface of the zirconium corundum layer 8. The diamond grinding layer 10 and the zirconium corundum layer 8 are disposed on the upper and lower sides of the second glass fiber layer 9, respectively, and the second glass fiber layer 9 is disposed and confined to the diamond grinding layer 10. Between the diamond grinding layer 10 and the zirconium corundum layer 8, the zirconium corundum layer 8 is fixedly installed on both sides of the abrasive layer 4 through the first glass fiber layer 7. The mesh-like first glass fiber layer 7 completes the bonding between the zirconium corundum layer 8 and the abrasive layer 4, preventing the abrasive material from flying out after the grinding wheel breaks. At the same time, the zirconium corundum layer 8 significantly improves the hardness and wear resistance of the grinding wheel, enhancing its compressive and abrasion resistance. The diamond grinding layer 10 is fixedly installed on the outside of the zirconium corundum layer 8 through the second glass fiber layer 9. The diamond grinding layer 10 is the core part of the grinding wheel responsible for grinding. The high wear resistance of diamond makes the grinding wheel wear less during use, extending the service life of the grinding wheel and improving the overall practicality and efficiency of the superhard abrasive composite grinding wheel.

[0023] In summary, when using this superhard abrasive composite grinding wheel with heat dissipation holes, the grinding wheel 1 is first fixed to the grinding machine by using the mounting part 2 in the middle of the grinding wheel 1 and the threaded mounting groove 3. The abrasive layer 4 is then fixed to the middle of the outer side of the mounting part 2. The conical heat dissipation holes 5 on the middle of the outer side of the abrasive layer 4 enhance air convection and reduce grinding temperature, thereby reducing thermal damage to the workpiece. At the same time, the heat dissipation groove 6, together with the conical heat dissipation holes 5, quickly dissipates the heat generated during the rotation of the grinding wheel 1 and prevents material debris from entering the grinding wheel. Then, the zirconium corundum layer 8 is fixedly installed on the abrasive layer 4 by the first glass fiber layer 7. On both sides, a mesh-like first glass fiber layer 7 is used to bond the zirconium corundum layer 8 to the abrasive layer 4, preventing the abrasive material from flying out after the grinding wheel breaks. At the same time, the zirconium corundum layer 8 significantly improves the hardness and wear resistance of the grinding wheel, enhancing its compressive strength and abrasion resistance. The diamond grinding layer 10 is fixedly installed on the outside of the zirconium corundum layer 8 using a second glass fiber layer 9. The diamond grinding layer 10 is the core part of the grinding wheel responsible for grinding. The high wear resistance of diamond makes the grinding wheel wear less during use, extending the service life of the grinding wheel and improving the overall practicality and efficiency of the superhard abrasive composite grinding wheel.
