Detailed Description
For further explanation of the technical solutions of the present invention, the following description will be made with reference to the accompanying drawings; as shown in fig. 1 and fig. 2, in this example, a steel wire with a diameter of 0.2 mm is selected as a metal wire, the metal wire is woven into a metal mesh with a pore diameter of 2 mm, the woven metal mesh is cut into a ring shape with an outer diameter of 150 mm and an inner diameter of 20 mm to form a metal mesh 12, a phenolic resin is coated near an inner pore of the metal mesh 12, the coating thickness is 0.1 mm, and a ring-shaped area with an outer diameter of 40 mm and an inner diameter of 20 mm is fully distributed to form a coating area 11; adopting a diamond electroplating process commonly used in the industry to electroplate diamond particles 13 on the surface of the metal mesh 12, and ensuring that the thickness of a plating layer is 0.08 mm, so as to form a framework 1; because the coating area 11 can not electroplate diamond and does not participate in cutting in the area, the cutting effect is ensured, meanwhile, diamond particles are saved, and the production cost is reduced; white corundum of 60 meshes, anhydrous gypsum of 150 meshes, phenolic resin of 150 meshes, asphalt of 200 meshes and an additive are mixed; the mixing ratio is 10: 2: 0.5: 0.2: 0.1, mixing and stirring uniformly to prepare an abrasive mixture; manufacturing a pressing die according to a die form universal in the industry, putting an abrasive material mixture into a bottom layer of the die, controlling the amount of the abrasive material mixture to be 50% of the total amount, putting a framework 1 into the pressing die, and paving the framework on the upper surface of the previously put abrasive material mixture; putting the rest half of the abrasive mixture on the upper surface of the framework 1, closing a pressing die, putting the pressing die into pressing equipment commonly used in the industry, and performing pressurization and heating pressing at the pressing temperature of 85 ℃ and the pressing pressure of 10MPa to symmetrically form abrasive composites 2 on two sides of the framework 1; because the abrasive mixture is embedded into the metal net at the 1 point of the framework and is pressed into a whole, and meanwhile, because the framework 1 is the metal net, the supporting force is large, the cutting blade can be made thinner; on the other hand, the surface of the framework 1 is provided with the diamond particles 13, the bonding force between the diamond particles and the metal net 12 is far greater than the bonding force of phenolic resin among the grinding materials, and the hardness of the diamond is quite high, so that the cutting piece can be ensured to be durable and can cut objects with high hardness; in this example, a stainless steel sheet is selected to manufacture the mounting ring 3, the diameter of the inner hole is ensured to be 20 mm, the outer diameter is ensured to be 40 mm, the section is U-shaped, the inner width of the U-shaped is equal to the thickness of the abrasive material combination 2, the mounting ring is embedded in the inner hole of the pressed abrasive material combination 2, the inner hole is tightly pressed, a label is attached to the position near the inner hole, and the mounting ring is arranged in a packaging bag, so that the implementation of the invention is completed.
When the cutting device is used, the cutting device is arranged on the abrasive wheel cutting machine, the abrasive wheel cutting machine is started, the cutting device rotates on the abrasive wheel cutting machine at a high speed, the outer circumference of the cutting device is contacted with an object to be cut, certain pressure is applied, and due to the high hardness of the cutting device, the cut object can be separated through the generated friction, so that the cutting function is realized.
