Abstract
A synthetic grindstone for performing a surface processing includes abrasive grains with an abrasive grain proportion (Vg) higher than 0 vol. % and equal to or lower than 40 vol. %, includes a nonwoven-fabric binder with a binder proportion (Vb) equal to or higher than 35 vol. % and lower than 90 vol. %. The synthetic grindstone has a porosity (Vp) higher than 10 vol. % and equal to or lower than 55 vol. %.
