High-quality grinding of polycrystalline silicon carbide …
Ground silicon carbide spherical surfaces with form accuracy -to-valley (PV) of 0.21–0.59 wave (0.13–0.37 m) and surface roughness of 9.92–17.22 nm Ra were obtained. Low machining-induced damage was found on the ground silicon carbide where defects were mainly associated with microstructural defects such as pores.
