China's first diamond laser marking machine came out, the laser beam diameter is only 5 μ M

Electric diamond is the symbol of eternal love. It is also the dream of many lovers to engrave the mark of love on the diamond. China University of Geosciences (Wuhan) has successfully developed China's first diamond laser marking machine. This machine can not only engrave the factory logo and product name on the diamond, but also engrave the "oath of alliance".

Professor Yuan Xinqiang, the inventor of the technology and Dean of the school of jewelry at China University of Geosciences, said that diamonds are the most hard material in the known universe, and diamonds used for jewelry decoration are very small in size, so it is very difficult to micro carve the diamond surface. He revealed that only the United States, Belgium, Israel and other countries with developed gem industry have diamond laser micro engraving technology. The technical breakthrough of China University of Geosciences in this field is of great benefit to the development of national gem industry in China.

This instrument can reduce the diameter of laser beam to 5 μ M. the operator only needs to set the font or graphics to be engraved on the computer connected with it, and the instrument can finish the precise characterization of characters with the minimum height of 50 μ m on the surface of diamond. It takes only 8 seconds to carve a character, but the loss of diamond is only one ten thousand carats, which has an impact on the weight and value of diamond Ignore.
