Mechanical grinding
Mechanical grinding is to grind the workpiece on a rotating abrasive tool, which is generally a round abrasive disc.
The grinding disc for mechanical grinding is usually made of cast iron, and the polishing disc is made of steel or copper. Suede and silk face plates are often used for polishing and surfacing cemented carbide, copper alloy, stainless steel and other sealing rings.
The surface of the metal grinding plate must be flat and free of defects, and the flatness needs to be trimmed to less than 0.05/1000mm. The radius of the disc shall be designed to be at least twice the diameter of the workpiece to be processed. The diameter range is generally 305~1620mm (16~64in), and the thickness is about 1/10~1/6 of the diameter. The disc surface is provided with grooves, which are designed to reduce the stress and deformation of the disc surface, facilitate heat dissipation, and facilitate the removal of waste abrasive and the inclusion of wear debris during grinding.
Surface radioactive and rhombic blocks are mostly used for rough grinding, concentric circles are mostly used for fine grinding, and end face threads (Archimedes spiral) are mostly used for polishing.
Grinding machine is the grinding equipment used in the mechanical seal manufacturing industry. It is composed of bed, base, reduction box, grinding disc, control ring (also called retaining ring or correction ring), limit support frame, etc.
During grinding, the workpiece is placed in the control ring, and the plastic isolation ring is used to evenly arrange the workpiece in the control ring. The grinding pressure is applied by the weight. When the grinding plate rotates, the control ring rotates in the limit support frame. In addition to rotation, the workpiece rotates on the grinding plate along with the control ring, and the surface is continuously ground under the action of the abrasive.
