The invention relates to a tread cleaning device grinder for a high-speed bullet train and a preparation process of the tread cleaning device grinder. The tread cleaning device grinder comprises a friction block and a back plate, the friction block makes contact with the back plate, and a connecting part embedded into the friction block is arranged on the back plate; the connecting part is barb-shaped, and during preparation, the back plate with the barb-shaped connecting part is put into a hot pressing mold; and a 0.1-1 mm exhaust micropore hot-pressing device is arranged on a hot-pressing head, and friction material components are injected into a mold to be subjected to hot-pressing forming. The friction material comprises 22-35 wt% of a tungsten-silicon dual-modified phenolic resin adhesive, 10-25 wt% of 3-5 mm heat conduction reinforced copper fibers, 20%-35% of nickel powder and 2-5 wt% of graphite which are impregnated in 16-30 wt% of porous ceramic particles. The working condition application requirements of grinding can be met, the thermal stability is high, no shedding or knotting can be achieved, and certain modification and the like can be achieved.
