Customized Shaped Sapphire Parts Sapphire Prism For Optical Use
Sapphire, which is derived from the Latin Spphins, which means
blue; it belongs to the corundum group of minerals in the trigonal
crystal system. In the gem world, all colors of gem-grade corundum
other than rubies are called sapphires.
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.
We can customize various shapes according to customers' drawings.
We also have precision, grinding, polishing and testing equipment
to ensure that each product meets the demanding requirements of
customers.
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 hemp 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.
