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

Abstract

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 phenomenon. The basic units are expanded by a dislocation technology so that the probability density of the grinding points in a domain after expansion is even. The grinding points are in the cylinder shapes of which the bottoms have circular beads, and the bending resistant strength and the chip discharge function of the grinding points can be improved.

Description

technical field [0001] The invention relates to a layout method of a grinding point group of a disc-type metal sanding sheet for grinding long fiber materials. Background technique [0002] The grinding and sanding of special long-fiber biomass materials such as wood and bamboo materials, human nails, etc. need to be completed with special grinding tools. For example, in toothpick manufacturers, a large number of such grinding tools are needed, and become Consumables. There is also a considerable amount of demand for nail clipper manufacturing factories. The suppliers of these products are all Japanese or Korean manufacturers. Over the years, the problems brought about are: (1) The domestic manufacturers who demand such products are relatively scattered, and the suppliers' procurement and supply channels are not timely and smooth, which will have a certain impact on production. (2) The price of the product is too high, but it is also a consumable product, which makes Chin...

Problems solved by technology

Over the years, the problems brought about are: (1) The domestic demand for such products is relatively scattered, and the channels for suppliers to purchase and supply are not timely and smooth, which will have a certain impact on production

(2) The price of the product is too high, but it is also a consumable product, which makes Chinese users feel that the cost of accessories is too high, which brings pressure on production costs, which is not conducive to survival and development in the fierce market competition
