Abstract
PURPOSE:To maintain the sharpness of a grindstone as well as to make favorable grinding performable by sintering and bonding plural sintered abrasive grains via a bonding material. CONSTITUTION:Fine powder diamond abrasive grains 1 of 2-4mum in mean grain size are sintered by 5-10 grains at a time at a temperature of about 600-1,000 deg.C with metal powder 6, forming a sintered abrasive grain group 2 making this metal powder a bonding material. This abrasive grain group 2 is sintered at the last sintered temperature or less than it with another metal powder 8, forming a grinding wheel 11 holding the abrasive grain group 2 with this metal powder 8 as a bonding material 4. At this time, bonding strength between the fine powder abrasive grain and the bonding material 7 is set to be smaller than that between the abrasive grain group 2 and the fine powder abrasive grain 1. In consequence, with the advance of grinding operation, an angular part of the fine powder abrasive grain 1 is worn out, and when load is imposed on this part grows large, the fine powder grain 1 falls off before the abrasive grain group 2 falls off, and adjacent fine powder grains 1 are projected to a surface of the grinding wheel 11 anew one after another, thus autonomous force is smoothly performed and each projection of abrasive grains 2 is smoothly performed.
