Single Crystal Grinding

01-08-2019· During grinding, slippages occurred along (0 0 1) crystal planes which are the close-packed plane of the YAG single crystal, i.e. the most likely to slip under a compressive stress. Since slippage occurred along the same crystal plane, i.e. the slip planes were parallel to each other in the subsurface, therefore, no brittle removal occurred during the grinding process.

01-01-2017· A predictive model of grinding force in MSG of three different orientations of single crystal sapphire: C-plane {0001}, A-plane {11 2 ¯ 0} and R-plane {1 1 ¯ 02} are established.. The MSG experiments results show that {0001} orientation could produce comparatively smaller grinding force which is almost 80% of the {11 2 ¯ 0} and 50%~65% of {11 2 ¯ 0}.

Fine Grinding (flat parts – single or double-side) is the abrasive machining process for removing material using a bonded Superabrasive wheel at low speed with a liquid to keep the part cool. The fixed grain of a geometrically indefinable cutting shape acts like a plow (fig. 3) and material is removed by micro-grooving /-cutting (fig. 4).
