Description

Technical Field

[0001] This invention relates to the field of grinding wheel technology, and particularly to a hollow bubble grinding wheel. Background Technology

[0002] Grinding wheels, also known as bonded abrasives, are classified according to the bonding agent used. Common types include ceramic (bonded) grinding wheels, resin (bonded) grinding wheels, and rubber (bonded) grinding wheels. Grinding wheels are the most widely used and extensive type of abrasive. They rotate at high speeds and can be used for rough grinding, semi-finishing, and finishing of the outer and inner diameters, planes, and various profiles of metal or non-metal workpieces, as well as for grooving and cutting.

[0003] Existing grinding wheels are all solid grinding wheels. When used in special scenarios such as holes and openings, the particles and powder ground off are not easily carried out and tend to accumulate, affecting processing efficiency. Summary of the Invention

[0004] This invention proposes a hollow bubble grinding wheel, which solves the problem that existing grinding wheels are all solid grinding wheels. When used in special scenarios such as holes, the particles and powder ground off are not easily carried out and tend to accumulate, affecting processing efficiency.

[0005] A hollow bubble grinding wheel has a grinding head and a grinding rod fixedly inserted into the grinding head in the radial direction. The grinding surface of the grinding head is provided with a plurality of receiving grooves, which can be used to receive particles generated during grinding. The manufacturing process of hollow bubble grinding wheels includes the following steps: S1. Mix alumina bubble balls, dextrin, clay, clay and borosilicate glass evenly, place them in a mold and press them to form a grinding wheel head model. The grinding wheel head model has a pre-drilled shaft hole in the axial direction. S2. Place the pressed grinding wheel head model into a sintering equipment and sinter it in a temperature range of 850℃ to 1300℃ to obtain the initial shape of the grinding wheel head. S3. Coat one end of the grinding wheel rod with epoxy resin, and then insert it into the shaft hole to ensure the concentricity of the grinding wheel rod and the initial shape of the grinding wheel head; S4. After the epoxy resin has cured, place the initial shape of the grinding head with the grinding wheel rod on the concentricity detection equipment to screen out products that meet the concentricity standard and remove products that do not meet the concentricity standard. S5. Use a diamond grinding wheel to dress the grinding surface of the initial grinding head, break the alumina air bubbles on the grinding surface, and form a receiving groove. The initial grinding head is made into the final grinding head.

[0006] Preferably, the receiving groove is at least one of a three-quarter sphere, a half sphere, or a quarter sphere.

[0007] Preferably, the grinding wheel head is one of the following shapes: spherical, hemispherical, mushroom-shaped, cylindrical, conical, bullet-shaped, disc-shaped, saucer-shaped, umbrella-shaped, cup-shaped, or bowl-shaped.

[0008] Preferably, in step S1, by weight, 68-73 parts of alumina bubble balls, 2-4 parts of dextrin, 10-15 parts of clay, 10-15 parts of earthenware, and 1-4 parts of borosilicate glass are used.

[0009] The beneficial effects of this invention are as follows: The hollow bubble grinding wheel of this invention uses alumina bubble balls, and the alumina bubble balls on the grinding surface of the grinding wheel head are ground down, so that the alumina bubble balls are broken and part of them are ground away. The remaining alumina bubble balls form a receiving groove. When used in special scenarios such as processing holes and openings, the receiving groove can hold some of the ground particles and powders, which is more conducive to the discharge of particles and powders and prevents the accumulation of particles and powders, thus affecting processing efficiency.

[0014] A hollow bubble grinding wheel has a grinding head 1 and a grinding rod 3 fixedly inserted into the grinding head in the radial direction. The grinding surface of the grinding head 1 is provided with a plurality of receiving grooves 4, which can be used to receive particles generated during grinding. The manufacturing process of hollow bubble grinding wheels includes the following steps: S1.

S4. After the epoxy resin has cured, place the initial shape of the grinding head with the grinding wheel rod 3 on the concentricity detection equipment to screen out products that meet the concentricity standard and remove products that do not meet the concentricity standard. S5. Use a diamond grinding wheel to dress the grinding surface of the initial grinding head, break the alumina air bubbles on the grinding surface, and form a receiving groove 4. The initial grinding head is made into the final grinding head 1.

[0015] In a preferred embodiment, the receiving groove 4 is at least one of a three-quarter sphere, a half sphere, or a quarter sphere. The receiving groove 4 can be at least one of a three-quarter sphere, a half sphere, or a quarter sphere. Of course, the alumina bubble spheres are broken randomly by the diamond grinding wheel, so the portion ground away is also random. Therefore, the shape of the receiving groove 4 is also random; it could be a three-quarter sphere, a half sphere, a quarter sphere, or some other shape.

[0016] As a preferred embodiment, the grinding wheel 1 is one of the following shapes: spherical, hemispherical, mushroom-shaped, cylindrical, conical, bullet-shaped, disc-shaped, saucer-shaped, umbrella-shaped, cup-shaped, or bowl-shaped.

[0018] The hollow bubble grinding wheel of this invention uses alumina bubble balls, and the alumina bubble balls on the grinding surface of the grinding head 1 are ground down, so that the alumina bubble balls are broken and part of them are ground away. The remaining alumina bubble balls form a receiving groove. When used in special scenarios such as processing holes and openings, the receiving groove can hold some of the ground particles and powders, which is more conducive to the discharge of particles and powders and prevents the accumulation of particles and powders, thus affecting processing efficiency.

[0019] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
