bitorihuaido grindstone and its production method

摘要

Process efficiency and process precision of grinding which is set beforehand, the porosity which process precision 0.1 - 1.6Rz (millimicron), process efficiency 0.1 - 2.0mm3/(mm sec) is based desirably (to be desirable 30 - 70 capacity %), concentration ratio of the abrasive grain (to be desirable 50 - 160), and abrasive grain diameter (to be desirable 10 - 90 millimicrons) the bitorihuaido grindstone and its production method of possessing.
