Diamond is one type of superhard material and cubic boron nitride is another. The two kinds of superhard materials after a series of machining and processing procedures can be made into a variety of tools and directly with them into a variety of functional devices, collectively referred to as superhard material products.
Mirror finishing refers to the process where the surface of a workpiece is polished to the point where it can reflect images like a mirror. This level of finish signifies exceptional surface quality, providing products not only with a high “aesthetic value” but also reducing notch effects, thereby extending the fatigue life of the workpiece. It holds significant importance in many assembly and sealing structures.
Why does a platinum ring lose weight after polishing? Over time, platinum rings tend to get scratched and lose their shine. To restore their appearance, polishing is required. When polishing a platinum ring, does it reduce its weight?
The primary goals of polishing molds are to increase the brightness and aesthetics of plastic molds and to make demolding easier.

Currently, the world’s popular high-temperature and high-pressure diamond synthesizing equipment mainly consists of two-sided tops (belt, which is mainly popular
In 1994, Thomas R. Anthony et al. of GE filed U.S. Patent 5,437,891 (issued in 1995) stating that the growth
Natural diamonds are produced at depths of over 130 kilometers. It has a unique cubic crystal structure. Each carbon atom in a diamond is bonded to four other carbon atoms, making it the hardest natural substance known in the world. How are diamonds formed? Let’s find out!
