Method for distributing grinding point group of disk type metal polishing sheet for grinding long fiber material

The invention discloses a method for distributing a grinding point group of a disk type metal polishing sheet for grinding a long fiber material. In the method, the grinding point group is formed by splicing basic units according to a sloping alveolate dislocation method; each basic unit is a regular hexagon formed by 12 congruent right-angle triangles, the boundary and the inner part are totally provided with 79 grinding points, and points at the boundary and the inner part of the first right-angle triangle in the counter-clockwise direction in the first quadrant are called generatrixes; the generatrixes are 10 grinding points which carry out optimization design and adopt a linear equation in two unknowns as a mathematical model; and the grinding points are in cylinder shapes of which the bottoms have circular beads. The grinding track overlapping degree of all the points is at minimum by the irrational number of a generatrix coordinate, and the grinding surface can be more even without groove mark phenomeno
