Polishing and buffing are finishing processes for smoothing a workpiece's surface using an abrasive and a work wheel or a leather strop. Technically, polishing refers to processes that uses an abrasive that is glued to the work wheel, while buffing uses a loose abrasive applied to the work wheel. Polishing is a more aggressive process, while ...
Synthetic diamond. Lab-grown diamonds of various colors grown by the high-pressure-and-temperature technique. Laboratory-grown ( LGD ), also called lab-grown diamond, [1] laboratory-created, man-made, artisan-created, artificial, synthetic, or cultured diamond, is diamond that is produced in a controlled technological process (in contrast to ...
Surface finishing. A drill bit with surface finishing to make the cutting edges harder. Surface finishing is a broad range of industrial processes that alter the surface of a manufactured item to achieve a certain property. [ 1] Finishing processes may be employed to: improve appearance, adhesion or wettability, solderability, corrosion ...
Chemical finishing of textiles is a part of the textile finishing process where the emphasis is on chemical substances instead of mechanical finishing. [1] [2] Chemical finishing in textiles also known as wet finishing. [citation needed] Chemical finishing adds properties to the treated textiles. Softening of textiles, durable water repellancy ...
Material properties of diamond. Burns above 700 °C in air. Diamond is the allotrope of carbon in which the carbon atoms are arranged in the specific type of cubic lattice called diamond cubic. It is a crystal that is transparent to opaque and which is generally isotropic (no or very weak birefringence ).
Diamond cutting is the practice of shaping a diamond from a rough stone into a faceted gem. Cutting diamonds requires specialized knowledge, tools, equipment, and techniques because of its extreme difficulty. The first guild of diamond cutters and polishers (Diamantaire) was formed in 1375 in Nuremberg, Germany, [1] and led to the development ...
Poly diamond powder is a kind of synthetic diamond which is synthesized through detonation. Compared to mono diamond, poly diamond powder has more crystal edges and grinding surface, where every crystal edge has grinding force. During the polishing process, big grit can fall into small pieces so it can keep the sustaining grinding force without ...
Diamond turning is turning using a cutting tool with a diamond tip. It is a process of mechanical machining of precision elements using lathes or derivative machine tools (e.g., turn-mills, rotary transfers) equipped with natural or synthetic diamond-tipped tool bits. The term single-point diamond turning ( SPDT) is sometimes applied, although ...
