Alumina and Silicon Carbide: Performance of Different Abrasives and Their Applications

There are many types of abrasives, and their selection principles are directly related to the physical and mechanical properties of the workpiece material being processed.  Generally, when grinding workpiece materials with high tensile strength, it is advisable to select tougher alumina-based abrasives. For workpiece materials with low tensile strength, it is preferable to choose silicon carbide abrasives, which are more brittle but have higher hardness. The tensile strength of some materials and the corresponding choice of abrasives are shown in Table 2-8.

Types and Selection of Bonding Agents for Abrasives: Ceramic, Resin, Rubber, and Magnesia

The performance of the binder in abrasives affects its reactivity with the abrasive grains and its strength. When the binder has good reactivity with the abrasive grains, their bonding force is strong, making it less likely for the abrasive grains to fracture or fall off. A high binder strength allows the abrasive grains to withstand higher grinding forces and also enables the grinding wheel to have higher rotational strength, making it less prone to breakage. Furthermore, when the binder reacts better with the abrasive grains, less binder is required for abrasives of the same hardness, resulting in a looser structure that benefits the grinding process.

Factors to Consider When Selecting Abrasive Hardness for Grinding

Reasonable selection of abrasive hardness is the key to achieving good grinding results. The most basic principle in selecting abrasive hardness is to ensure that the abrasive has proper self-sharpening properties during grinding, avoiding excessive wear of the abrasive. It is also essential to prevent excessively high grinding temperatures during the process.

Quality Standards and Corresponding Testing Methods for Abrasive Grains

Grinding processes rely on abrasive grains to achieve high surface quality, precise dimensional tolerances, and process stability. As one of the most critical machining operations, grinding serves as both a finishing method for hard-to-machine materials and a shaping technique for various applications. During grinding, the grinding tool is a key element alongside cooling lubricants and grinding machines. The tool's structure, chemical composition, surface morphology, and wear behavior significantly influence workpiece quality, surface integrity, process stability, and productivity. Grinding tools come in various forms, including solid wheels, tools with grinding layers, or coated tools like belts, pads, or discs. Abrasive grains are the primary agents of material removal during grinding, embedded within a bonding matrix. The bond hardness determines the tool's hardness and influences its wear behavior.
