The utility model relates to a polishing linen wheel, comprising an annular sisal wheel sheet and a nonmetallic wheel axle, wherein the nonmetallic wheel axle is combined with the annular sisal wheel sheet in a hot-pressing mode and is provided with a central through hole. A metal ring is concealed at the inner part of the annular sisal wheel sheet along a circumferential direction, and the whole nonmetallic wheel axle is in a basin shape. The outer-ring periphery of the nonmetallic wheel axle is provided with a groove matched with the inner ring of the annular sisal wheel sheet, and the basin bottom of the nonmetallic wheel axle is inward concavely provided with an annular positioning groove. The design of the regular-hexagon center hole of the nonmetallic wheel axle is suitable for the central shafts of a variety of polishers, so the product applicability is strong. The design of wheel-shaped teeth of the periphery of the nonmetallic wheel axle can let the nonmetallic wheel axle to firmly occlude with the sisal wheel sheet, so the loosening between the wheel axle and the wheel sheet is avoided. The annular sunken design of the back of the nonmetallic wheel axle is matched with the positioning iron core of the polisher, so that the polishing linen wheel is coaxial with the polisher, and the assembly and work efficiency is increased.
