Abstract (en)
A resinoid grinding wheel of the present invention has low grinding resistance and is capable of providing a ground workpiece excellent in ground surface quality without burn mark while maintaining essential properties of the resinoid grinding wheel such as low elastic modulus and strong force for holding abrasive grains. A typical resinoid grinding wheel of the present invention includes 25 parts by volume of Al2O3 abrasive grains with grain size of #150, 20 parts by volume of organic hollow material with average particle diameter of 80 mu m, and 10 parts by volume of pores having 1 mm in size. They are all dispersed in 40 parts by weight of a bond made of cured epoxy resin.
