ABRASIVE GRAIN TOOL AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide an abrasive grain tool capable of controlling abrasive grain distributing density, not leaving lines on a grinding material surface and fastening abrasive grains on a working surface in a single layer and its manufacturing method. SOLUTION: This abrasive grain tool to fasten the abrasive grains on the working surface in a single layer constitutes its characteristic feature of arranging the abrasive grains at a position where individual intersections of a lattice are displaced at random by a distance of less than three times of an average grain diameter of the abrasive grains respectively in the crossed two lattice line direction or in the X direction and the Y direction and fastens the abrasive grains on the working surface in a single layer by assuming the virtual lattice on the working surface of the tool, and this manufacturing method of the abrasive grain tool constitutes its characteristic feature of arranging the abrasive grains at a position where the individual intersections of the lattice are displaced at random by the distance of less than three times of the average grain diameter of the abrasive grains respectively in the crossed two lattice line direction or in the X direction and the Y direction by assuming the virtual lattice on the working surface of the tool.
