In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 2 to 14, the grid polishing wheel of the present embodiment includes a wheel body 500, and the wheel body 500 is formed by bonding and curing a plurality of layers of grid cloth 100 through an adhesive layer 400.

The utility model adopts the grid cloth 100 as the base material of the wheel body of the polishing wheel, the grid cloth is provided with meshes, so that a large number of gaps 300 can exist between the interior of the wheel body and the surface (the meshes 200 of each layer of grid cloth 100 form the gaps 300 of the wheel body; the meshes 200 of the adjacent grid cloth are communicated to form the gaps 300 of the wheel body), as shown in fig. 14; the shape of the mesh cloth is not limited, and the mesh cloth can be square holes, polygonal holes and the like. The polishing wheel made of the mesh cloth has larger and more gaps and good heat dissipation in the polishing process; the grid cloth is provided with the meshes, and the wheel body is provided with the gaps, so that certain rigidity and elasticity can be brought in the polishing process, and the cutting can be more smoothly performed; and because the grid cloth is provided with meshes, and the wheel body is provided with a gap, the wheel body forms a three-dimensional sawtooth polishing structure, and the polishing capacity of the polishing wheel is improved. The layers of the mesh cloth 100 are bonded and cured to form the wheel body with an integral structure, so that most of the wheel body can be utilized to participate in polishing operation, the residual parts of the corresponding wheel body are less, and the wheel body is fully used; after the outer layer of the wheel body is worn, the inner layer of the grid cloth can generate the same grinding effect as the outer layer. The meshes of the mesh cloth 100 are obvious and regular; the mesh 200 is distributed in an array on the grid cloth 100.

Further, the mesh holes 200 of each layer of mesh cloth are communicated with the mesh holes 200 of the adjacent mesh cloth to form the wheel body space 300, as shown in fig. 14 and 15. That is, the mesh holes 200 of each layer of mesh cloth form the gaps 300 of the wheel body; the mesh openings 200 of adjacent mesh cloths are communicated with each other to form the wheel body space 300. The wheel body has a void 300 in both the interior and the surface.

The reinforced chopped fiber can be one or a mixture of chopped basalt fiber, chopped glass fiber and chopped carbon fiber; preferably, the reinforcing chopped fibers are chopped basalt fibers. The crystal whisker can be one or a mixture of more of calcium sulfate crystal whisker, calcium carbonate crystal whisker, aluminum oxide crystal whisker, zinc oxide crystal whisker and silicon carbide crystal whisker; preferably, the whiskers are calcium sulfate whiskers. The mesh fabric is a woven fabric (such as plain weave mesh fabric or twisted mesh fabric), and when the design that the adhesive layer 400 contains the whiskers is adopted, the whiskers can penetrate into the warps and wefts of the mesh fabric, particularly can be adsorbed at the intersection of the warps and wefts of the mesh fabric to form a multi-point bonding structure microscopically, so that slippage between the warps and wefts of the mesh fabric can be avoided. The use of the whisker-containing adhesive layer 400 also increases the grinding ratio (the ratio of the amount of material removed from the workpiece to the amount of wear of the polishing wheel).

The mesh sizes of the adjacent meshes 100 are equal, i.e. the mesh sizes of the adjacent meshes are the same, and the meshes of the adjacent meshes may be aligned or staggered. The mesh sizes of the adjacent meshes 100 are not equal, that is, the mesh sizes of the adjacent meshes are different, so that the meshes of the adjacent meshes are necessarily staggered.

The warp-wise and weft-wise mechanical properties of the mesh fabric 100 are substantially the same, and particularly the breaking force of the mesh fabric 100 in the warp-wise and weft-wise directions is substantially the same. The breaking tension is an important index of the mechanical property of the base material of the grid polishing wheel, the grid cloth 100 plays a role of a framework in the grid polishing wheel, the grid polishing wheel (or the grid cloth 100) can be acted by forces in various directions in the polishing process, so that the grid polishing wheel is required to have uniform tensile, compression and bending resistance, the mechanical property of the grid polishing wheel is required to be uniform, the abrasive tool can be uniformly consumed in the polishing process, the longitudinal and latitudinal mechanical properties of the grid cloth 100 are basically consistent, particularly the longitudinal and latitudinal breaking tension of the grid cloth 100 is basically consistent, namely, the ratio of the longitudinal and latitudinal breaking tension of the grid cloth 100 is about 1, and the grid polishing wheel is an optimal and preferred design; of course, a ratio of breaking tension of the scrim 100 in the warp direction to that in the weft direction of 0.5-2 is also possible. Ideally, the complete matching of the breaking force of the mesh fabric 100 in the warp direction and the breaking force of the weft direction is optimal, but the breaking force of the actually manufactured mesh fabric 100 in the warp direction and the breaking force of the actually manufactured mesh fabric 100 in the weft direction are deviated, so that the mechanical properties of the mesh fabric 100 in the warp direction and the weft direction are substantially matched, and particularly the breaking force of the mesh fabric 100 in the warp direction and the weft direction is substantially matched.
