Structural ceramics have been widely used in engineering parts. It, however, is very difficult to grind the ceramics with desired shape and dimensional accuracy because of their high hardness, strength, and brittleness. Grindability of structural ceramics are quite different as they have different mechanical and physical properties. This paper compares the grindability of structural ceramics such as Al₂O₃Si₃N₄and SiC. The grinding experiments include the measurement of grinding force, surface roughness. and SEM observation. The experimental results indicate that Si₃N₄consumes the highest specific grinding energy among the three kinds of ceramics. It was also found that there is no corelationship between grindability and surface roughness of ground surface.
