However, in practical use, the required cutting force cannot be achieved by using a resin centerless mill for high-hardness steel materials, and the required precision cannot be achieved by using a ceramic centerless mill. The prior art discloses an assembled centerless grinding wheel and a preparation method thereof, wherein the assembled centerless grinding wheel comprises a rough grinding wheel, a fine grinding wheel and a polishing wheel which are sequentially connected from left to right, and also discloses the centerless grinding wheel which consists of a metal matrix and an abrasive layer; the grinding layer is composed of a rough grinding layer, a half grinding layer and a fine grinding layer, wherein the rough grinding layer, the half grinding layer and the fine grinding layer are adhered to the metal substrate, the rough grinding layer is arranged above the half grinding layer, and the half grinding layer is arranged above the fine grinding layer. The existing spliced grinding wheel solves the problem of multiple working procedures, rough grinding and polishing can be realized by one-time processing, but the existing spliced grinding wheel is feasible for common metal processing, and has the problem of poor processing quality for high-speed grinding (the linear speed is conventionally considered to be 100 m/s). The applicant discloses a novel ceramic resin composite centerless grinding wheel before, which comprises a matrix, a ceramic grinding material layer and a resin grinding material layer; the inner diameter of the ceramic grinding material layer is consistent with the inner diameter of the resin grinding material layer, and the outer diameter of the ceramic grinding material layer is consistent with the inner diameter of the resin grinding material layer; a concave hole is formed in one surface of the ceramic abrasive layer, which is in contact with the resin abrasive layer; a bulge is arranged on one surface of the resin abrasive layer, which is contacted with the ceramic abrasive layer; the bulges are filled in the concave holes; mixing the raw materials of the ceramic abrasive layer (the abrasive grain size is 80#) and pouring the mixture into a die with a ceramic matrix, carrying out cold pressing at a small pressure for shaping, then placing millimeter-sized resin microspheres or plastic particles and the like on one surface contacted with the resin abrasive layer, carrying out cold pressing at a large pressure to enable the microspheres and the like to be embedded into ceramic powder, and carrying out hot pressing and sintering to obtain an integrated intermediate structure of the matrix and the ceramic abrasive layer, wherein macroscopic holes are formed on the surface of the ceramic abrasive layer and are called concave holes; and then, mixing the raw materials of the resin abrasive layer (the abrasive grain size is 1500#) and pouring the mixture into a die with an intermediate structure, filling the concave holes with powder, cold pressing, hot pressing and curing to obtain the novel ceramic resin composite centerless grinding wheel, and curing the powder filled in the concave holes as a protrusion. The macroscopic pores cause the interfacial effect of the resin grinding material layer and the ceramic grinding material layer to be not very good, the preparation is also complicated, and the polishing effect is slightly poorer than that of the prior production; in order to improve existing processing quality, there is a need for improved formulations for new ceramic resin composite centerless grinding wheels to meet production applications.
