Grinding as a pre-treatment method for HF-HNO 3-H 2 O solution etching of diamond wire sawn (DWS) multi-crystalline (multi-Si) silicon wafers was proposed and researched. Significant improvement in morphological uniformity and decrease in light reflectivity of the wet acid etched surface textures were achieved with the pre-treatment.

Grinding is a material removal and surface generation process used to shape and finish components made of metals and other materials. The precision and surface finish obtained through grinding can be up to ten times better than with either turning or milling. Grinding employs an abrasive product, usually a rotating wheel brought into

Grinding is a subset of cutting, as grinding is a true metal-cutting process. Each grain of abrasive functions as a microscopic single-point cutting edge (although of high negative rake angle), and shears a tiny chip that is analogous to what would conventionally be called a "cut" chip (turning, milling, drilling, tapping, etc.) [citation needed].
