The invention discloses a ceramic crystallite corundum coated abrasive tool fabric base special for a fiber board and a treatment process thereof. The treatment process of the ceramic crystallite corundum coated abrasive tool fabric base special for the fiber board comprises the following steps that (1) a gray fabric with the specific surface area being 300-400 m<2>/g is adopted as the fabric base for production; (2) a first non-sand-planting face gluing material, a second non-sand-planting face gluing material and a sand-planting face gluing material are prepared separately; (3) the first non-sand-planting face gluing material is adopted to coat the non-sand-planting face of the fabric base in a scrapping mode for the first time; (4) the sand-planting face gluing material is adopted to coat the sand-planting face of the fabric base in a scrapping mode; (5) the second non-sand-planting face gluing material is adopted to coat the non-sand-planting face of the fabric base in a scrapping mode for the second time; and (6) the treated fabric base is ironed and shaped. The peel strength of the fabric cloth treated through the treatment process can reach (300-350) N/5cm; warp strength and weft strength are the same, and the warp mechanical property and the weft mechanical property are the same; the surface of the fabric base is smooth, and the ceramic crystallite corundum coated abrasive tool fabric base is suitable for production of a ceramic crystallite corundum coated abrasive tool product for efficient and high-precision grinding.
