Description

A grid polishing wheel

technical field

The invention relates to a grid polishing wheel, which belongs to the technical field of abrasive tools.

Background technique

Abrasives are tools for grinding and polishing. Most of the abrasives are artificial abrasives made of abrasives and binders, and there are also natural abrasives that are directly processed from natural ore rocks. In addition to being widely used in machinery manufacturing and other metal processing industries, abrasive tools are also used in food processing, paper industry and processing of non-metallic materials such as ceramics, glass, stone, plastic, rubber, and wood.

The polishing wheel is a wheel-shaped abrasive tool. The polishing wheel is used for grinding or polishing the surface of the tool or the coating. The existing polishing wheel usually adopts the abrasive cloth wheel, nylon wheel, sticky abrasive cloth wheel, resin grinding wheel and so on. There are many kinds of abrasive cloth wheels, such as flat abrasive cloth wheels, thousand impellers, and handle abrasive cloth wheels.

Specifically, the flat abrasive cloth wheel is made by cutting the abrasive cloth into sheets, and then stacking the formed abrasive cloth sheets on the tray gluing position according to a certain rule, and then adding a binder between the tray and the abrasive cloth sheets. After curing , that is, a flat abrasive cloth wheel is made, as shown in Figure 1a. The thousand impellers are made by covering one end of the formed abrasive cloth sheets in a radially close arrangement, then covering the other end cover, and adding a binder between the two end covers and the abrasive cloth sheets for curing, that is, the thousand impellers are made, such as shown in Figure 1b. The abrasive cloth wheel with handle is to place the formed abrasive cloth sheets in a radial and close arrangement in a specific auxiliary tool. A through hole is reserved in the specific auxiliary tool, and the round handle is inserted into the through hole, and then the abrasive cloth sheets around the round handle are placed Add the binder in between, and after curing, remove the auxiliary tool to make the abrasive cloth wheel with handle, as shown in Figure 1c. The preparation method of nylon wheel usually adopts non-woven fabric dipping, overlapping and pressing, and then curing, as shown in Figure 1d. The sticky abrasive cloth wheel folds multiple layers of cloth together, then cuts it, fixes it into a disc shape with a rope, applies animal glue along the circumferential surface, and then sands it. Repeat the above steps to the appropriate size, and then cure it. That is, a sticky abrasive cloth wheel is prepared, as shown in Figure 1e. The resin grinding wheel is a cymbal-shaped or disc-shaped form by mixing sand and glue under pressure, such as the cymbal-shaped resin grinding wheel as shown in Figure 1f; and the disc-shaped resin grinding wheel as shown in Figure 1g. However, the polishing wheel prepared by the manufacturing method of the prior art has insufficient grinding sharpness, poor adhesion, and the abrasive is easy to fall off, thereby affecting the grinding efficiency. Moreover, the existing polishing wheels with various structures not only suffer from low sharpness of grinding, but also have problems such as difficulty in dissipating heat, poor rigidity and elasticity, and difficulty in cutting.

SUMMARY OF THE INVENTION

The purpose of the present invention is to: in view of the above-mentioned problems, to provide a grid polishing wheel, the present invention adopts grid cloth as the base material of the polishing wheel body, which can improve the grinding ability, heat dissipation capacity and chip removal of the polishing wheel. ability, and has a certain rigidity and elasticity.

The technical scheme adopted in the present invention is as follows:

A mesh polishing wheel, comprising a wheel body, the wheel body is formed by bonding and curing several layers of mesh cloth, each layer of mesh cloth is attached with abrasive, and the mesh of the mesh cloth is attached with abrasive; In any layer of mesh cloth, at least some of the mesh holes are not blocked.

The present invention adopts mesh cloth as the base material of the wheel body of the polishing wheel, and the mesh cloth has mesh holes, so that a large number of gaps can exist inside and on the surface of the wheel body (the mesh holes of each layer of mesh cloth form the wheel body The meshes of the adjacent mesh cloths are connected to form the voids of the wheel body), the meshes of the mesh cloth are not limited in shape, and can be square holes, polygonal holes, etc. The polishing wheel made of mesh cloth has larger and more gaps in the polishing wheel, and has better heat dissipation during the grinding process, reducing the probability of the workpiece being burned; and because the mesh cloth has mesh holes and the wheel body has gaps during grinding In the process, it can bring a certain degree of rigidity and elasticity, which can make the cutting more smooth; and because the mesh cloth has mesh holes, the wheel body has gaps, and abrasives are attached to the mesh holes, then there is abrasive attached to the gaps, and the wheel body is formed. The three-dimensional sawtooth grinding structure can improve the sharpness of grinding and the grinding ability of the grinding wheel. Abrasives are attached to each layer of mesh cloth, and several layers of mesh cloth are bonded and solidified to form a wheel body with an integrated structure, so that most of the wheel body can be used to participate in the grinding operation. There will be less residue left after cutting, making the most of it. In the present invention, the mesh cloth is made into the wheel body by bonding and curing, so that the density of the abrasives in the inner and outer layers of the wheel is uniform (in other words, the abrasives can be distributed in the wheel body more evenly). Therefore, the outer layer of the wheel meshes After the cloth structure is worn, the inner mesh cloth structure can produce the same grinding effect as the outer layer. In any layer of mesh cloth, at least some of the mesh holes are not blocked, so that the interior and surface of the wheel body can effectively form voids.

Further, the meshes of each layer of mesh cloth and the meshes of adjacent mesh cloths are connected to form the gaps of the wheel body, and abrasives are attached to the gaps.

Further, for the abrasives attached to any layer of mesh cloth, part of the abrasives are located in the mesh holes of the mesh, and part of the abrasives are located at the mesh holes of the adjacent mesh cloth.

Alternatively, the meshes of adjacent meshes are aligned; or, the meshes of adjacent meshes are staggered.

Further, the abrasive is attached to the lines of the mesh. In the wheel body of the mesh polishing wheel of the present invention, the abrasive is attached to the lines of the mesh cloth, and the abrasive is not easy to fall off, and the mesh cloth is equivalent to the skeleton of the wheel body.

Further, the abrasive is attached to each layer of mesh cloth through an adhesive layer, and several layers of mesh cloth are bonded and cured through the adhesive layer to form the wheel body.

Further, the adhesive layer contains reinforced chopped fibers or/and whiskers for enhancing the mechanical properties of the mesh cloth. The mechanical properties, especially the tensile strength, of the mesh cloth and the mesh polishing wheel body can be improved, the rupture of the mesh polishing wheel can be avoided, and the safety of the mesh polishing wheel can be improved. This design is especially suitable for mesh fabrics made of materials with relatively low tensile strength such as linen or cotton.

Preferably, the mechanical properties of the mesh fabric in the warp direction and the weft direction are substantially the same. The mechanical properties of the grid polishing wheel are made more uniform, so that the polishing wheel can be consumed more evenly in the grinding process.

Optionally, the wheel body is formed by laminating several layers of mesh cloth; or, the wheel body is formed by winding several layers of mesh cloth; a wheel body through hole is formed in the middle of the wheel body. The wheel body can be formed by stacking, bonding, and curing several layers of mesh cloth; it can also be formed by winding, bonding, and curing several layers of mesh cloth; both can be formed into the structure of the wheel body. The through holes in the wheel body facilitate the use of mesh polishing wheels for polishing operations.

Optionally, the grid polishing wheel is a cymbal-shaped tray grid polishing wheel, a cymbal-shaped integrated grid polishing wheel, a covered grid polishing wheel, a handle grid polishing wheel, a cylindrical grid polishing wheel or a sheet-shaped polishing wheel. Grid polishing wheel; of which,

The shown cymbal-shaped tray grid polishing wheel includes the wheel body, one end of the wheel body is connected with a cymbal-shaped tray, the tray has a tray through hole in the middle, and the tray through hole and the wheel body through hole are substantially coaxial;

Detailed ways

All features disclosed in this specification, or all disclosed steps in a method or process, may be combined in any way except mutually exclusive features and/or steps.

Any feature disclosed in this specification, unless expressly stated otherwise, may be replaced by other equivalent or alternative features serving a similar purpose. That is, unless expressly stated otherwise, each feature is but one example of a series of equivalent or similar features.

As shown in FIG. 2 to FIG. 15 , a mesh polishing wheel in this embodiment includes a wheel body 500 . The wheel body 500 is formed by bonding and curing several layers of mesh cloth 100 . The abrasive 200 is attached, and the mesh 130 of the mesh cloth is attached with the abrasive 200; in any layer of mesh 100, at least part of the mesh is not blocked.

The present invention uses mesh cloth as the base material of the wheel body of the polishing wheel, and the mesh cloth has mesh holes, so that a large number of gaps can exist inside and on the surface of the wheel body (the mesh holes 130 of each layer of mesh cloth 100 form a mesh). The gap 300 of the wheel body; the connection of the meshes 130 of the adjacent mesh cloth also forms the gap 300 of the wheel body. The shape of the mesh of the mesh cloth is not limited, and it can be a square hole, a polygonal hole and the like. The polishing wheel made of mesh cloth has larger and more gaps in the polishing wheel, and has better heat dissipation during the grinding process, reducing the probability of the workpiece being burned; and because the mesh cloth has mesh holes and the wheel body has gaps during grinding In the process, it can bring a certain degree of rigidity and elasticity, which can make the cutting more smooth; and because the mesh cloth has mesh holes, the wheel body has gaps, and abrasives are attached to the mesh holes, then there is abrasive attached to the gaps, and the wheel body is formed. The three-dimensional sawtooth grinding structure can improve the sharpness of grinding and the grinding ability of the grinding wheel. Abrasive 200 is attached to each layer of mesh cloth 100, and several layers of mesh cloth 100 are bonded and solidified to form a wheel body with an integrated structure, so that most of the wheel body can be utilized to participate in the grinding operation. The grinding residue of the body will be less, making the most of it. In the present invention, the mesh cloth is made into the wheel body by bonding and curing, so that the density of the abrasives in the inner and outer layers of the wheel is uniform (in other words, the abrasives can be distributed in the wheel body more evenly). Therefore, the outer layer of the wheel meshes After the cloth structure is worn, the inner mesh cloth structure can produce the same grinding effect as the outer layer. In any layer of mesh cloth 100, at least part of the mesh holes are not blocked, so that the interior and surface of the wheel body can effectively form gaps. Preferably, in any layer of mesh cloth 100, all mesh holes Design that is not blocked; specifically, the mesh of any layer of mesh is not blocked by the abrasive on this layer of mesh, but may be blocked by the abrasive on the adjacent layer of mesh (non-sealed). blocked). The meshes of the mesh cloth 100 are obvious and regular; the meshes 130 are distributed on the mesh cloth 100 in an array. Optionally, abrasives 200 are attached to one or both sides of each layer of mesh cloth 100 .

Further, as shown in FIG. 15 , the meshes 130 of each layer of mesh cloth and the meshes 130 of adjacent mesh cloths are connected to form a gap 300 of the wheel body, and the abrasive 200 is attached to the gap 300 . That is, the meshes 130 of each layer of mesh cloth form the gaps 300 of the wheel body; the meshes 130 of adjacent mesh cloths are connected to form the voids 300 of the wheel body. There are gaps 300 both inside and on the surface of the wheel body.

Further, as shown in FIG. 16 , for the abrasives 200 attached to any layer of mesh cloth 100, some abrasives 200 are located in their own meshes 300, and part of the abrasives 200 are located in the meshes 300 of adjacent meshes. At this point, part of the abrasive 200 is located between the lines of adjacent meshes 100 . For the part of the abrasive 200 to be located at the mesh hole 300 of the adjacent mesh cloth, it means that the part of the abrasive 200 may be located on the inner side of the mesh hole 300 of the adjacent mesh cloth, or may be located in the adjacent mesh cloth The outer side of the mesh 300 is shown in FIG. 16 .

Alternatively, the mesh holes 130 of adjacent mesh cloths are aligned; or, the mesh holes 130 of adjacent mesh cloths are staggered. The design includes four implementations, the first is that the meshes 130 of all the meshes are in positive alignment; the second is that the meshes 130 of all the meshes are staggered; the third is that all the adjacent meshes 130 The meshes 130 of the meshes are staggered, and the meshes 130 of non-adjacent meshes can also be aligned; the fourth is that among all adjacent meshes, some adjacent meshes The mesh holes 130 of the mesh cloth are aligned, and the mesh holes 130 of some adjacent mesh cloths are staggered. Among the above-mentioned four embodiments, the first embodiment can maximize the mesh gap of the wheel body, and the gap of the wheel body can penetrate through the two end surfaces of the wheel body, so as to improve the heat dissipation effect of the grinding wheel, so that the grinding wheel can be cut out. smoother. The similarity between the second, third and fourth types is relatively large, and the meshes 130 of the adjacent mesh cloths are all staggered, so that the abrasives attached to the mesh wiring strips are located at the meshes of the adjacent mesh cloths. , so that more abrasives are exposed in the gap of the wheel body, which can improve the grinding ability of the polishing wheel.

Further, as shown in FIGS. 14 and 15 , the abrasive 200 is attached to the lines of the mesh cloth 100 . In the wheel body 500 of the mesh polishing wheel of the present invention, the abrasive is attached to the lines of the mesh cloth 100 , and the abrasive is not easy to fall off. The mesh cloth 100 is equivalent to the skeleton of the wheel body 500 . Since the abrasive 200 is attached to the lines of the mesh cloth 100, as shown in Figures 14b and c, for any layer of mesh cloth, the line segments between two adjacent meshes of the mesh cloth are all attached There are abrasives, so that a large number of line segments with abrasives are formed in the mesh cloth, similar to the existence of a large number of "small abrasive belts (or small abrasive lines)" fixed at both ends in the polishing wheel. At the same time, a large number of "small abrasive belts" grind the workpiece from all directions, which can improve the grinding ability of the grid polishing wheel. The lines of the mesh cloth 100 are the basic units constituting the mesh cloth, which is easy to understand. For example, the mesh cloth includes warp threads 110 and weft threads 120, and the warp threads 110 and the weft threads 120 are interwoven to form the mesh cloth 100 with mesh holes 130; The warp threads 110 and the weft threads 120 are the lines of the mesh fabric 100 . The mesh 100 may be a plain-woven mesh or a twisted mesh, or a woven fabric in other weaving forms. The plain weave mesh cloth, as shown in FIG. 12 , includes warp threads 110 and weft threads 120. The warp threads and weft threads are intertwined, so that a mesh cloth with meshes is formed by plain weaving. The lines of the mesh cloth 100 are plain weave meshes. The warp 110 and the weft 120 of the cloth. The twisted mesh fabric, as shown in FIG. 13, includes warp 110 and weft 120, the warp 110 includes twist 111 and ground warp 112, and the twisted warp and ground warp are twisted with each other and interwoven with the weft, thereby twisting weave A mesh cloth with mesh is formed. Between the adjacent wefts 120, the twisted warp 111 and the ground warp 112 are twisted to each other to form a twisted portion 113, and the weft 120 is sandwiched by the twisted warp 111 and the ground warp 112. The lines of the cloth 100 are the warp 111, the ground warp 112, and the weft 120 of the twisted mesh fabric. Fig. 14a shows a schematic diagram of the prior art dense cloth base after implanting abrasives, Fig. 14b shows a schematic diagram of the plain woven mesh cloth of the present invention after implantation of abrasives, and Fig. 14c shows a schematic diagram of the twisted woven mesh cloth implanted with abrasives It can be seen that if the dense cloth base (such as paper, steel paper, woven cloth, non-woven fabric, composite matrix or film) in the prior art is used as the base material of the grinding wheel, the abrasive can only be planted When the mesh cloth of the present invention is used as the base material of the polishing wheel, the abrasive can be implanted into the surface and mesh holes of the base material, and attached to the lines of the mesh cloth 100 . Preferably, the cross-sectional areas of the warp threads 110 and the weft threads 120 are substantially equal, and the warp threads 110 and the weft threads 120 are made of the same material.

Optionally, the mesh cloth 100 is hemp fiber, cotton fiber, nylon fiber, paper fiber, glass fiber, basalt fiber, carbon fiber, polyester fiber, polyethylene fiber, magnesium chloride fiber, acrylic fiber, aramid fiber , woven fabrics made of one or more fiber materials of cellulose acetate, viscose fiber, dog hair fiber, horse hair fiber, pig hair fiber and wool fiber.

Further, as shown in FIG. 15 , the abrasive 200 is attached to each layer of mesh cloth 100 through an adhesive layer 400 , and several layers of mesh cloth 100 are bonded and cured through the adhesive layer 400 to form the wheel body 500 . In combination with any layer of mesh cloth 100, when at least part of the mesh holes are not blocked, the mesh holes of the mesh cloth are not blocked by the abrasive on the mesh cloth layer, and of course not by the adhesive layer. 400 blocked.

The wheel body of the grid polishing wheel of the present invention has the dual characteristics of coated abrasives and fixed abrasives. Coated abrasives refer to abrasives in which the abrasive is adhered to the flexible substrate with a binder, also known as flexible abrasives. Bonded abrasives are tools with a certain shape and a certain grinding ability made of abrasives (grinding materials) and binders. In the wheel body of the mesh polishing wheel of the present invention, the abrasive 200 is attached to each layer of mesh cloth 100 through the adhesive layer 400 , similar to the form of a flexible abrasive tool; several layers of mesh cloth 100 are bonded through the adhesive layer 400 The wheel body 500 is formed by curing, which is similar to the form of a bonded abrasive tool. The abrasive cloth in the background art is a typical flexible abrasive tool, and the abrasive cloth wheel is an extended product of the abrasive cloth; the resin abrasive wheel in the background art is a typical fixed abrasive tool.

Compared with the abrasive cloth wheel of the present invention, the abrasive cloth wheel is basically the closer the abrasive is to the center of the abrasive cloth wheel, the denser the abrasive cloth wheel is, and the closer the abrasive cloth wheel is to the center of the abrasive cloth wheel, the harder the abrasive cloth wheel is, and the grinding ability becomes worse; The abrasive of the grinding wheel can be distributed evenly in the wheel body (it has the advantage of bonded abrasives). Compared with the abrasive cloth wheel, the abrasive distribution is more uniform, the grinding performance is stable, the performance is stable, and it has stronger grinding ability, heat dissipation ability and chip removal ability.

Compared with the resin grinding wheel, the mesh polishing grinding wheel of the present invention is in that the abrasives of the resin grinding wheel are bonded to each other. During the grinding process, some abrasives will fall off if they fail to participate in the grinding process. The proportion of abrasives is large, and the amount of abrasives is large; and the abrasives 200 of the grid polishing wheel of the present invention are attached to the grid cloth 100 (with the characteristics of coating abrasives), and are not easy to fall off, and the proportion of abrasives in the grid polishing wheel is relatively Smaller, can save abrasive; compared with resin grinding wheel, abrasive should not fall off, and has stronger grinding ability, heat dissipation ability and chip removal ability, and has certain rigidity and elasticity.

Compared with the abrasive cloth wheel of the present invention, after the abrasive on the surface of the abrasive cloth wheel is consumed, it must be used again after applying glue and sanding, which is troublesome and difficult to achieve continuous grinding operation. ; And the abrasive of the grid polishing wheel of the present invention is distributed in the wheel body, and the grinding operation can be carried out continuously.

Alternatively, as shown in FIG. 15 , a part of the abrasive 200 exposes the adhesive layer 400 ; or, the entire abrasive 200 is wrapped by the adhesive layer 400 . When a part of the abrasive 200 is exposed to the adhesive layer 400, the abrasive 200 can directly participate in the grinding, which can increase the sharpness of the grinding working surface of the wheel body and improve the grinding efficiency. When all the abrasives 200 are wrapped by the adhesive layer 400, during the grinding operation, the adhesive layer 400 wrapped outside the abrasives will be instantly worn away, and the abrasives can expose the adhesive layer 400, which basically does not affect the grinding of the wheel body. Grinding sharpness and grinding efficiency of the working surface. That is, no matter if part of the abrasive 200 is exposed to the adhesive layer 400 or the whole of the abrasive 200 is wrapped by the adhesive layer 400, the wheel body has good grinding ability, and the difference between the two solutions is not obvious. In the actual manufacturing process of the polishing wheel, in most cases, the entire abrasive 200 is wrapped by the adhesive layer 400 . Of course, there are also cases where a part of the abrasive 200 is exposed to the adhesive layer 400 . That is, in the wheel body, a part of all the abrasives may be exposed to the adhesive layer 400; also all the abrasives may be wrapped by the adhesive layer 400; or a part of some abrasives may be exposed to the adhesive layer 400, The entirety of the other abrasives is wrapped by the adhesive layer 400 . This is all within the protection scope of the present invention.

Further, the adhesive layer 400 contains reinforced chopped fibers or/and whiskers for enhancing the mechanical properties of the mesh cloth. For a wheel-shaped abrasive tool, during the high-speed rotation of the abrasive tool, the base material of the abrasive tool will be subjected to a large centrifugal force, so the mechanical properties of the base material need to meet the needs of use, especially the base material needs to have a relatively high centrifugal force. Strong tensile strength; mesh fabrics with obvious meshes of the same material and specifications and dense cloth bases without meshes or without obvious meshes (such as paper, steel paper, woven fabric, non-woven fabric, composite matrix) (or film), it is obvious that the tensile strength of the mesh cloth is lower than that of the dense cloth base; therefore, it can be seen that the wheel body made of mesh cloth can improve the grinding ability, heat dissipation ability and chip removal ability. At the same time, part of the tensile strength is sacrificed; when the rotational speed of the abrasive tool is extremely high, the abrasive tool with mesh cloth as the base material may be broken, which has a potential safety hazard, which limits the maximum rotational speed that the abrasive tool can achieve. Therefore, the present invention proposes a design in which the adhesive layer 400 contains reinforced chopped fibers or/and whiskers for enhancing the mechanical properties of the mesh cloth, which can improve the mechanical properties of the mesh cloth and the mesh polishing wheel body , especially the tensile strength, avoid the rupture of the grid polishing wheel, and improve the safety of the grid polishing wheel. The reinforced chopped fibers can be a mixture of one or more of chopped basalt fibers, chopped glass fibers, and chopped carbon fibers; preferably, the reinforced chopped fibers are chopped basalt fibers. The whiskers can be a mixture of one or more of calcium sulfate whiskers, calcium carbonate whiskers, aluminum oxide whiskers, zinc oxide whiskers, and silicon carbide whiskers; preferably, the whiskers are calcium sulfate whiskers. The mesh is a woven fabric (such as a plain-woven mesh or a twisted mesh). When the adhesive layer 400 contains whiskers, since the whiskers are short fibers at the micro-nano level, the whiskers can It penetrates into the warp and weft lines of the grid cloth, especially can be adsorbed at the intersection of the warp and weft lines of the grid cloth, microscopically forms a multi-point bonding structure, and can also avoid slippage between the warp and weft lines of the grid cloth. When the design including whiskers in the adhesive layer 400 is adopted, the grinding ratio (the ratio of the amount of material removed from the workpiece to the amount of wear of the polishing wheel) can also be improved.

Preferably, the mechanical properties of the mesh fabric 100 in the warp direction and the weft direction are substantially the same. The warp direction of the mesh cloth 100 refers to the length direction of the warp threads of the mesh cloth 100 , and the weft direction of the mesh cloth 100 refers to the length direction of the weft threads of the mesh cloth 100 . In particular, the breaking tensions of the mesh fabric 100 in the warp direction and the weft direction are basically the same. The breaking force is an important indicator of the mechanical properties of the mesh polishing wheel base material. The mesh cloth 100 acts as a skeleton in the mesh polishing wheel. During the grinding process, the mesh polishing wheel (or the mesh cloth 100) It will be affected by various directional forces, which requires the mesh polishing wheel to have relatively uniform tensile, compressive, and bending resistance, and the mechanical properties of the mesh polishing wheel are required to be relatively uniform, so that the abrasive tool can be used in the grinding process. The consumption is relatively uniform, and the mechanical properties of the mesh cloth 100 in the warp and weft directions are basically the same, especially the breaking tension in the warp and weft directions of the mesh cloth 100 is basically the same, that is, the warp direction of the mesh cloth 100 is basically consistent. The ratio of the breaking force to the weft direction is about 1, which is the best and preferred design; of course, it is also feasible that the ratio of the warp and weft breaking force of the mesh fabric 100 is 0.5-2. In an ideal state, it is optimal that the breaking forces of the mesh fabric 100 in the warp and weft directions are completely consistent, but in the actual manufacture of the mesh fabric 100, the breaking forces in the warp and weft directions may deviate. Therefore, The mechanical properties of the mesh fabric 100 in the warp direction and the weft direction are basically the same, especially the breaking tensions in the warp direction and the weft direction of the mesh fabric 100 are basically the same.

Alternatively, as shown in FIG. 2 to FIG. 11 , several layers of mesh cloth 100 are stacked to form the wheel body 500 ; or, several layers of mesh cloth 100 are rolled to form the wheel body 500 ; the wheel body The center of 500 is provided with a wheel body through hole 501 . The wheel body 500 may be formed by laminating, bonding, and curing several layers of mesh cloth 100 ; it may also be formed by winding, bonding, and curing several layers of mesh cloth 100 ; both can be formed into the structure of the wheel body. The through hole 501 of the wheel body is convenient to use the grid polishing wheel for polishing operation. Optionally, as shown in FIG. 10 , for the winding-type mesh polishing wheel, the wheel body of the mesh polishing wheel is provided with a plurality of through holes 502 , and the through holes 502 pass through two parts of the wheel body 500 . The end face can improve the heat dissipation capacity, chip removal capacity and rigidity of the mesh polishing wheel. Of course, the through holes 502 can also be provided for the laminated mesh polishing wheel.
