Grinding, Sanding and Lapping. The quartz crystal is then polished by grinding and sanding. The grinding wheel is dotted with very coarse bumps made out of an extremely hard material such as silicon carbide. It spins rapidly and is pushed against the quartz to slowly wear it away into a chosen shape. Once the gem cutter creates a rough shape by ...

The smoothed-particle hydrodynamics (SPH) method was introduced to simulate the quartz glass grinding process with a single grain under micro-nano scale. To investigate the mechanism of brittle–ductile transition, such factors as the machining depth, grinding force, maximum equivalent stress, and residual stress were analyzed. The simulation results indicate …
