Diamond lapping liquid is a kind of liquid with lapping function which takes micron diamond powder as abrasive and is dispersed into the liquid medium by adding the dispersant or other methods.

According to the types of diamond, it can be divided into mono-crystal diamond lapping liquid, polycrystalline diamond lapping liquid and nano diamond lapping liquid. And according to the dispersion medium, it can be divided into water-based dispersion medium, oil-based dispersion medium and universal medium (emulsion medium).

Micron diamond powder plays a crucial role in the lapping liquid, mainly manifested in its high hardness and wear resistance, making it an ideal raw material for lapping and polishing high-hardness materials such as hard alloys, ceramics, gemstones, and optical glass.

The hardness of micron diamond powder is extremely high, which enables it to maintain a relatively high lapping rate during the processing and form a high-quality processed surface at the same time.

For example, in the processing of optical glass and gemstones, the micron diamond powder lapping liquid can ensure the high quality of the processed surface while maintaining a high lapping rate, meeting the application scenarios where these materials have extremely high requirements for processing precision.
