What Is The Grinding Process Of The Insulation Ball Valve?

Grinding is a common finishing method for the sealing surface of valves during manufacturing. Grinding can make the valve sealing surface obtain high dimensional accuracy, geometric shape roughness and surface roughness, but it cannot improve the relative position accuracy between the surfaces of the sealing surface.

2 Piece Threaded Ball Valve During grinding, the grinding tool and the sealing ring surface fit together well, and the grinding tool makes complex grinding movements along the fitting surface. Abrasives are placed between the grinding tool and the sealing ring surface. When the grinding tool and the sealing ring surface move relative to each other, some of the abrasive particles in the grinding agent slide or roll between the grinding tool and the sealing ring surface, cutting off a very thin layer of metal on the sealing ring surface. The peaks on the sealing ring surface are first ground off, and then gradually reach the required geometric shape. Grinding is not only a mechanical processing process of abrasives on metals, but also a chemical action. The grease in the abrasive can form an oxide film on the processed surface, thereby accelerating the grinding process.
