The spherical finish of the high-precision steel ball refers to the surface flatness and brightness of the steel ball. Finish is an important indicator to measure the brightness of the surface of the object, which is especially important for high-precision parts such as steel balls. The finish of high-precision steel ball directly affects its product performance, the following will discuss the relationship between the finish and product performance from several aspects.
The finish of high-precision steel balls is closely related to their performance in terms of friction and wear. As a mechanical component, steel balls are often used in bearings, transmission devices and other equipment that require high-speed movement or heavy duty work. Under these working conditions, the surface finish of the steel ball has a direct impact on its friction and wear properties. The higher the finish of the steel ball, the smoother the surface, the lower the coefficient of friction, and the generation of friction heat is relatively reduced, thereby reducing the energy loss and wear degree caused by friction. Therefore, the higher the finish of the high-precision steel ball, the better its friction and wear performance under high-speed motion and heavy load conditions.
Secondly, the finish of the high-precision steel ball is related to its performance in terms of sealing. In some special fields, such as aerospace, precision instruments, etc., there are high requirements for the sealing of materials. The finish is one of the important factors affecting the tightness. High precision steel ball surface finish is high, can provide better sealing performance, avoid gas or liquid leakage, but also reduce the entry of external impurities, protect the internal equipment from the external environment pollution and corrosion.
In addition, the finish of the high-precision steel ball is also related to its performance in terms of conductivity. In some applications that need to conduct heat or current, the conductivity of a material is one of the important parameters to determine its suitability. The finish of high-precision steel balls is directly related to the thermal and electrical conductivity of their surfaces. High finish steel ball surface flatness, can provide better thermal and conductive channels, thereby helping to improve the conductivity of the product.
The finish of the high-precision steel ball is also related to its performance in corrosion resistance. As a metal material, steel ball is easily affected by corrosion. The surface of the steel ball with high finish is relatively smooth, which can reduce the surface area and contact surface in contact with the external medium, thereby reducing the chemical reaction with the external medium and reducing the possibility of corrosion of the steel ball. Therefore, the higher the finish of the high-precision steel ball, the better its corrosion resistance.
