This paper discusses the grinding of sapphire for mirror surfaces by coarse grain size diamond wheels. Sapphire is a hard-to-machine material because it has excellent mechanical properties and indentation hardness. Since it is effective for hard materials to use metal-bonded diamond wheels, the authors had two experiments to investigate mirror surface grinding by coarse grain size diamond wheels. The 1st experiment was investigating appropriate grinding conditions, and the 2nd experiment was investigating protrusion height of abrasive grains. Although the conventional methods could not acquire mirror surface, the results of the experiments show that mirror surface (Ra: 5 nm <) were obtained by the #270 and #325 mesh size wheels. These results indicate the possibility of decreasing grinding processes by coarse grain size diamond wheels.

“…However, sharper cutting edge is fragile and its fragment easily ruins ground surface in grinding of hard and brittle materials. Therefore, the truncation of grinding wheel has also been employed after dressing to improve ground surface [17][18][19].…”

“…It has been known that generation of ground surface is the response of the work material to the kinematical mapping of wheel protrusion topography on to the work surface [1,2,[15][16][17][18]. Therefore, hypothetical grinding modeling has often been introduced to describe stochastic nature of 3D gain shape orientation and position in wheel protrusion topography due to difficulties of measuring wheel topography.…”

“…Therefore, hypothetical grinding modeling has often been introduced to describe stochastic nature of 3D gain shape orientation and position in wheel protrusion topography due to difficulties of measuring wheel topography. In modeling, the abrasive grains are assumed to be spherical [1,3,15], ellipsoidal [1] or conical [18] in shape so as to be able to model random distribution of 3D abrasive grains in grinding wheel. They can be used to describe effect of grain protrusion distribution on ground surface, but it cannot display random distribution of grain protrusion attitudes on wheel working surface.…”

“…Therefore, the complex wheel topography has been simulated in consideration with surface topographical parameters [16], and also truncation of dressed wheel topography has been applied to precision grinding [17][18][19]. However, they did not quantitatively describe 3D spatial orientation of grain cutting edges on wheel working surface.…”
