Opis:

Standard ceramic abrasive tools are manufactured using glass bonds or mineral resources, in which the microstructure of the bonding bridges cannot be controlled. In this study, a new type of glass-crystalline bond was used to combine mixed abrasive grains from microcrystalline and monocrystalline corundum into an abrasive tool. The glass-crystalline bond has a fine crystalline structure (particle size of the crystalline phase: 1-1.5 µm) and perfectly moistens the abrasive grains. This fact and the generated crystalline phase with a high coefficient of brittle fracture resistance enable the production of tools with a higher porosity and self-sharpening ability in comparison to grinding wheels with the use of industrial bond, which results in high performance indices with a longer service life.
