2.1: Grinding Grinding can be defined as the rapid removal of material from a sample either to reduce it to a suitable size or to remove large irregularities from the surface. The grinding wheel or plate typically rotates at a high speed (around 200-1000rpm) and a coarse, bonded abrasive (> 40 µm) is used.

Edge Grind Wheels Edge grind wheels are manufactured with tightly distributed fine grade synthetic diamond particles to enable and provide a more consistent wafer-to-wafer edge grind process. Wheels can be tailored to your desired groove dimensions and adjusted to a grit size of up to 3,000 for fine grind applications.

As grinding feed from the center to the edge of the steep aspheric surface, the sapphire crystal planes gradually turn to the N/R-planes and finally to the A/M-planes. As affected by the material-removal anisotropy of sapphire, the ground surface quality of different positions on the steep aspheric surface is different.

Sapphire; Zerodur® (Schott) ... For a polished edge, the optic will undergo a series of edge grinding at finer and finer grits until the final edge is completely smooth. In conclusion, the choice of bevel shape, type, and tolerances will impact the pricing of the optic, but also overall performance in the actual application. ...

Grinding. The grinded sample on the picture shows the result of edge rounding by semi-automatic machinery. The edges are rounded but a bit chamfered and not fully rounded. This chamfered surface structure is the result of multiple grinding movements along the edge. Grinding can create a rounded edge based on multiple chamfers.
