In the field of superhard material processing, synthetic diamond abrasive powder is an indispensable tool. It is used for grinding hard and brittle materials to achieve high surface finish. So, what exactly is synthetic diamond abrasive powder? How does it work? Let us explore.
Synthetic diamond abrasive powder is made of diamond micron powder abrasive and powder binder. Among them, diamond micron powder is the main component; they are bonded together by the abrasive to form a powder. Diamond particles are superhard materials with extremely high hardness and wear resistance. The powder binder acts as a lubricant. During the grinding process, the diamond particles inside the grinding powder continuously roll, generating both squeezing and cutting actions, leading to numerous indentations on the surface of the workpiece.
The raised indentations are cut by subsequent abrasive grains, continuously forming chips that are removed, thereby making the workpiece surface flat and smooth. Meanwhile, the abrasive can bond the diamond particles together to form a powder for ease of use and control. In use, synthetic diamond abrasive powder typically requires cooperation with a grinder or manual grinding. It is mainly used for polishing and grinding hard and brittle materials.
Suppose a piece of hard alloy needs processing. We use synthetic diamond abrasive powder for the task. First, we apply the synthetic diamond abrasive powder to the surface of the hard alloy, then use a grinder to polish it. During the polishing process, diamond particles continuously scrape and grind the surface of the hard alloy, making it gradually smooth and flat. Meanwhile, the abrasive firmly bonds the diamond particles together, ensuring uniformity and stability in the polishing effect. After a few minutes of polishing, the hard alloy surface exhibits high quality smoothness and flatness, significantly improving processing efficiency and quality.
The selection of synthetic diamond abrasive powder mainly depends on the required surface finish of the processed workpiece, processing efficiency, and the original surface finish of the workpiece. For larger allowances requiring high processing efficiency, coarser grit sizes can be chosen. For smaller allowances requiring high smoothness, finer grit sizes can be selected.
In the field of mechanical processing, synthetic diamond abrasive powder is widely used in the processing of various superhard materials. It is suitable for grinding and polishing high-hardness materials such as glass, ceramics, gemstones, hard alloys, and others, including high-precision instruments, cutting tools, and other high-finish workpieces. It is also suitable for the grinding and polishing of irregular workpieces made from the aforementioned materials that are difficult to process with traditional grinding tools. It can effectively improve processing efficiency and quality, reduce tool wear, and lower costs.
In the construction industry, synthetic diamond abrasive powder is used for the processing and polishing of materials such as stone and glass, producing smooth surfaces and high-quality finished products.
Synthetic diamond abrasive powder is also used in the grinding and polishing of tungsten steel molds, optical molds, injection molds; metallographic analysis processes; and dental materials (dentures).
Synthetic diamond abrasive powder is a very practical tool that plays an important role in the processing of superhard materials. By understanding the basic concepts, characteristics, application scenarios, and working principles of synthetic diamond abrasive powder, we can better recognize and utilize this tool to improve processing efficiency and quality.
