The main component of sapphire is alumina (Al2O3). Corundum contains trace elements such as iron (Fe) and titanium (Ti), and presents colors such as blue, sky blue, and light blue, among which the bright sky blue is the best.
Sapphire precision parts are generally used in the wear-resistant and high-temperature parts of instruments, meters, and equipment.
Sapphire has a hardness of 9 on the Mohs level, second only to diamond, and has good wear resistance. At the same time, it has excellent chemical stability and can resist almost any acid and alkali corrosion. In addition, the maximum temperature of sapphire reaches 2060℃. It is precisely because of the above advantages of sapphire that sapphire is used in instrumentation equipment, which can significantly increase the service life and withstand various harsh environments.
The precision parts made of sapphire include: water meter and electric meter bearing, chemical pump through valve body, textile machine stopper, etc.
Sapphire precision parts often have complex shape requirements and precise sealing requirements.
Sapphire parts in today's society more and more extensive use, with the development of modern science and technology, sapphire non-metallic materials in all walks of life have been used, most people are very clear about the use of sapphire, it is made into parts used in their own industry, sapphire has an important advantage is hard enough, so most can be used as parts to support the core of the machine.
Although sapphire has some special properties, but processing is more difficult, making parts is not easy, in fact, the international sapphire parts processing process is in the confidential stage, outsiders are not aware that as to its processing difficulties or need to control surface quality, how to avoid the presence of points and traces in the process of processing, slightly careless, this process on worship, there is a certain loss, and must meet the corresponding standards to be sold, to ensure dimensional accuracy and smoothness This is the key technology for processing,Especially in the polishing process, but also directly affect the surface quality of parts, so this time you have to use high-speed finishing, fine grinding and rough grinding together, improve the roughness of the surface of the finished parts, and secondly for polishing to create favorable conditions, such parts processing is perfect, quality and precision are in line with the standards, so that parts sold directly.
