PURPOSE:To grind a soft, ungrindable material as well as to make a work of high load and low grinding speed grindable, by forming a solid lubricant plating layer on a grinding wheel. CONSTITUTION:A grinding wheel consists of the following method that super abrasive grains 1 are fixed on a base metal (base plate) 2 by means of an electrodeposition process, on top of which a plating film (bond) 3 mixing and including a solid lubricant and wear-proof powder applied to chemical plating is bonded. At this time, a plating bond 4 by the electrodeposition process has thickness commensurate to 40-60% of an abrasive grain diameter, and the plating film 3 including the solid lubricant and the wear-proof powder formed on this plating bond 4 has thickness commensurate to 20-50% of a super abrasive grain diameter. With the grinding wheel formed like this, a soft, ungrindable material can be ground and, what is more, a work is grindable at high load and low grinding speed.
