PURPOSE: To provide a cutting grinding wheel that epochally improves the cutting accuracy and cutting yield rate of a workpiece in checking any possible deformation value of this diamond and carbon nitride cutting grinding wheel being thin in blade thickness. CONSTITUTION: In this cutting grinding wheel made up of attaching diamond abrasive grains and carbon nitride abrasive grains tight to a wheel spindle stock plate end, a surface of this wheel spindle stock plate made of sheet is coated with a cemented carbide material layer of 5 to 20μm in thickness by a PVD process.
