The working mechanism of Ceramic Aluminium Oxide Abrasive
Ceramic abrasive particle is composed of multiple sub-micron tiny crystals. During the use process, the tiny crystals on the surface of the abrasive particle are passivated, and under the action of the grinding force, they fall off along the crystal surface of the abrasive particle and are continuously exposed. A new grinding blade is produced to keep the abrasive particles in a sharp state so that Ceramic Aluminium Oxide has good self-sharpening.
Under normal circumstances, Ceramic Aluminium Oxide Abrasives are mixed with other abrasives and used together. The abrasive particles work together under the control of the binder. Because Ceramics has better toughness than other abrasives, under the effect of the same grinding force, the other abrasive particles break before the Ceramics abrasive particles, causing the Ceramic Aluminium oxide abrasive particles to protrude slightly and the surface of the abrasive tool, and there are "micro-plow marks" on the surface of the workpiece " Therefore, when selecting the Ceramics particle size, it is necessary to balance the efficiency and the surface finish of the workpiece.
The performance of different ceramic abrasives, different particle shapes and different grinding pressures are also very different. Because Ceramics aluminium oxide has a suitable particle size shape and a reasonable microstructure, experiments show that it not only performs well at low pressure, but also makes it easier to grind hard materials and has a wide range of applicability.
