GRINDING WHEEL AND MANUFACTURE THEREOF

摘要

PROBLEM TO BE SOLVED: To obtain long-term stable cutting quality through the excellent supply of a polishing solution and discharge of chips while obtaining the holding force and necessary protruding height of abrasive grains by setting wax material thickness to be specific times as large as an abrasive grain diameter, and forming a chip pocket with base metal matrix exposed with a width specific times as large as the abrasive grain diameter between the abrasive grains. SOLUTION: In arranging abrasive grains 2 in one layer on a base metal 2 for brazing, the abrasive grains 2 are held with a wax material thickness W of about 1/3-1/2 times as large as an abrasive grain diameter(d),and a chip pocket T with the matrix of the base metal 1 exposed with a width about 2/3-2.5 times as large as the abrasive grain diameter(d) between the adjacent abrasive grains 2 is regularly formed. Such a wax material thickness W can ensure the protruding height of the abrasive grains 2 required to exhibit excellent cutting quality while ensuring the holding force of the abrasive grains 2, and the regular formation of the chip pocket T with the exposed matrix of the base metal 1 permits the uniform distribution of the abrasive grains 2 and excellent supply of a polishing solution and discharge of chips.
