Abstract

A ceramics dress substrate of the present invention capable of both performances of cutting a cut material with a high accuracy and dressing a diamond cutting grindstone with an excellent cutting property and an reduced wearing amount of the grindstone. This ceramics dress substrate comprises sintering a mixture of ceramics grinding particles and a silicate mineral, The ceramics grinding particles are preferably uniformed and have a scratch hardness ranging from 6 to 10. Alumina grinding particles, silicon carbide and mullite are preferably used as the ceramics grinding particles, and a kaolin mineral, pyrophyllite, montmorillonite, sericite, talc and chlorite are preferably used as the silicate mineral. The ceramics dress substrate is preferably coated with glass.
