• To abrade — (Technical, rare) To perform an abrasion operation; cutting or smoothing a rigid surface through friction with abrasive materials; to grind or polish industrially.
• Abrading — The action of abrading and its result; a technical process of processing, finishing, or cleaning a mechanical surface through intense friction with abrasive materials; (by extension) wear caused to a material by a hard external agent.
• Filing — The act of amilduing and its result; the mechanical or manual process of smoothing, filing, or partially grinding a textile, wooden, or metallic piece. It represents a preliminary technological stage where coarse irregularities are removed before fine polishing or aesthetic finishing of the product.
• Brightening — The act of brightening and its result; a technological process through which the brightness of a surface, the clarity of a transparent medium, or the vividness of a color is intensified. In metallurgy and precision glass industry, brightening represents the final microscopic finishing operation that eliminates residual micro-roughness, ensuring optimal reflective performance according to quality standards.
