Ductile-Mode Grinding with 140 Mesh Wheel.30... 

Grinding operation is one of the most effective methods used for hig smoothness machining of fine ceramics. It is difficult, however, to achieve crack-free high smoothness surfaces by ductile-mode grinding because of their mechanical properties of high brittleness [1]. Therefore, it is necessary... 

This chapter introduces that the coarse 140-mesh diamond wheel can be used for ultra-smoothness grinding of fine ceramics. First of all, we discuss that ductile-mode grinding of fine ceramics with the coarse 140-mesh metal-bonded diamond wheel is possible because of the experimental relationship between the table speed and the groimd workpiece smiace. Second, the influence of the speed of the wheel and the workpiece material on ductile-mode grinding is explained. Finally, the newly developed ductile-mode ultra-smoothness grinding method with coarse-grain-size wheel, in which the resultant smiace roughness is below about 10 ran (P-V) and 1 nm (RMS), is introduced. 

Considering the results mentioned above, ductile-mode grinding with the 140-mesh wheel of low concentration of 50 is possible in the plunge grinding of HPSC ceramic with a conventional surface grinder. Nevertheless,... 

As stated above, ductile-mode grinding of fine ceramics is possible with plunge grinding with the coarse 140-mesh grain-size diamond wheel. The 3D surface roughness in ductile-mode plunge grinding, however, is limited... 

Ductile-mode grinding of fine ceramics with the coarse 140-mesh metal-bonded diamond wheel has been shown to be possible in plunge surface grinding. It is estimated that the thermal effect due to the large wear land of the cutting edge on the 140-mesh wheel surface has considerable effect on...

Ductile-mode grinding can be implemented even on a common grinder, by controlling the wheel topography. 

The ductile-mode grinding of brittle optical parts is studied in this research. The implementation of ductile-mode cutting requires expensive items like ultraprecision vibration-free rigid machine tools, high-resolution feeding motion control, submicron grit wheels, clean work environment, and so on. The conclusions of this study are as follows ...
