The internal grinding process has precise and narrow tolerance areas in both its size and form-shaping aspects. In the conventional grinding process, which grinds normal tempered hardened steel, aluminum oxide is predominantly used as a grinding wheel material. This has the advantage of self-sharpening during the process. Together with this conventional material, CBN has emerged as a new substitution in steel grinding. In this study, grinding characteristics when using ceramic and CBN wheels for internal grinding were analyzed. Ceramic wheel cutting edge sharpness is much better than the CBN wheel, and in the CBN wheel case, initial wheel status causes glazing and loading which slightly increase grinding power.
