箇所の外観を低下させるなどという問題があった。However, in such a manufacturing method, the unevenness on the back surface which is the reference surface 2 appears as it is as a variation in the thickness dimension,
There is a problem in that the thickness dimension varies between adjacent fiber boards, and the variation in the thickness dimension at the joint portion between the fiber plates deteriorates the appearance of the joint portion.

Has a high density on the back surface side and a low density on the upper layer portion. Then, the back surface of such an original plate 1 is polished with an endless sandpaper a to form a reference surface 2, and then the original surface 1 is used as a reference.
The surface layer of is also sanded with sandpaper a.

ものである。In this way, the reference surface 2 is formed by polishing the back surface of the original fiberboard 1 and the surface is polished by using the reference surface 2 as a reference. The surface 2 has no unevenness, and the surface is finished on the basis of the reference surface 2 having no unevenness to improve the accuracy of the thickness dimension. The cutting allowance for polishing the back surface having high density and high strength may be about 0.2 to 0.3 mm. By the way,
Conventionally, only the surface finish is used, and the variation degree σ of the thickness dimension is about 0.05, and when the surface finish is polished based on the reference surface 2 as in the present invention, the dimensional accuracy is It was found that the degree of variation σ of σ was about 0.028. In other words, the thickness dimension accuracy is increased while avoiding a decrease in the strength of the fiber board A.

法の精度を高めることができるという利点がある。As described above, according to the present invention, since the reference surface is formed by polishing the back surface of the original fiber board and the surface is polished by using this reference surface as a reference, the back surface is formed by polishing finish. Since there is no unevenness on the reference surface and the surface is polished and finished on the basis of the reference surface having no unevenness, there is an advantage that the accuracy of the thickness dimension of the fiber board can be increased.
