The invention discloses a method for processing the surface texture of wood floor, which processes the surface texture of the wood floor by using a circular saw blade. The device of the invention comprises a worktable (3); a group of disk saw bits (4) with adjustable height are arranged below the worktable (3); and the worktable (3) is provided with an angle-adjustable baffle plate (6). The method adopts the common disk saw bits to process the surface texture of the wood floor, and can form different nostalgic textures by changing the saw tooth shape, the number and space of the disk saw bits, the angle of the disk bits and the wood floor, the moving speed of the wood floor and the height of the disk saw bits on the wood floor. The method is simple and practicable, does not need special equipment, and can finish the texture processing of the wood floor by only simply improving the common disk saw bits. The method has the advantages of simple structure, little investment, convenient daily maintenance and no need of inputting the maintenance cost.
