Introduction to Diamond Micropowder

Diamond micro powder, as a superhard abrasive with super strong grinding ability, is increasingly valued in developed countries. The grinding ability of diamond micro powder includes its own wear resistance and wear resistance, as well as the grinding ability of the workpiece, which depends on its particle size, hardness, strength, thermal and chemical stability, and particle shape.
Diamond micro powder refers to diamond particles with a particle size less than 60 microns. There are two types of diamond powder: single crystal diamond powder and polycrystalline diamond powder.
1. Single crystal diamond micro powder is made by grinding artificial diamond single crystal abrasive particles through a special processing method.
2. Polycrystalline diamond micro powder is made from graphite through a unique directional sandblasting method. The shock wave of high explosive directional blasting accelerates the flying metal plate, impacts the graphite plate, and converts the graphite into polycrystalline diamond.
Diamond micro powder has high hardness and good wear resistance, and can be widely used in cutting, grinding, drilling, etc. It is an ideal raw material for grinding and polishing hard alloys, ceramics, gemstones, and optical glasses. Diamond micro powder products are components and tools made by processing diamond micro powder.
As far as the particle size is concerned, diamond micropowder belongs to submicron, micron and nanometer powders. Compared with coarse powder, diamond micro powder has significantly increased surface functional groups and surface area, and the interaction between particles has significantly increased. In addition, as the particle size is refined, the particle strength will inevitably increase and the inherent defects will decrease. It can be seen that the production process of diamond micro powder is quite difficult. It is not only a process of particle refinement, but also accompanied by changes in crystal structure and surface physicochemical properties. So the production process of diamond micro powder involves multidisciplinary engineering and technical issues in powder engineering, mechanics, physical chemistry, mechanics, detection technology, and modern instruments.

How to choose diamond coated cutting tools

Like any other cutting tool, the lifespan of stone carving knives varies, mainly depending on the material being cut, the selected feed rate and cutting speed, as well as the geometric shape of the workpiece. Generally speaking, the lifespan of diamond coated tools for processing graphite is 10-20 times that of uncoated hard alloy tools, and in some cases may even be longer. In this way, almost any machining task can be completed with a single tool without the need for tool replacement due to tool wear, avoiding machining interruptions and recalibration, making it possible to achieve unmanned machining. In the processing of composite materials, it is also entirely possible to achieve a longer tool life

Do you know the raw materials for high-quality cutting blades?

Glass cutting blades are particularly suitable for accurate cutting and slotting of optical and electronic components due to the strong holding ability and high wear resistance of diamond abrasive particles by binders.

How to choose between using CBN grinding wheel or diamond grinding wheel?

CBN and diamond belong to the category of super abrasives, and are called super abrasives because their hardness is much higher than other traditional abrasives. So, both are super abrasives, how do you distinguish between the two, and how do you choose the grinding wheel abrasives that are suitable for your own production? Firstly, we need to understand the characteristics of both.

Development status of diamond micro powder industry: The industry is developing towards intelligent production

Diamond micro powder refers to diamond particles with a particle size smaller than 54 microns and a chemical composition of carbon, which is the hardest substance in nature. Diamond micro powder is a micron or submicron level ultrafine diamond powder formed by processing diamond single crystals through crushing, ball milling, and other processes. Diamond has high strength and good wear resistance, with a Mohs hardness of 10 and a microhardness of 10000kg/mm2. Its microhardness is 1000 times higher than that of quartz and 150 times higher than that of corundum. Therefore, diamond micro powder, as a superhard abrasive, has unparalleled grinding ability compared to other products and is increasingly receiving high attention from developed industrial countries.

Semiconductor Industry's Expectations for High Quality Diamond

Semiconductor materials are a type of functional material with conductivity between conductive and insulating materials at room temperature. Its conductivity will significantly change with temperature, light exposure, and doping, especially doping can change the conductivity and type of semiconductor, which is the basic basis for its wide application in manufacturing various electronic components and integrated circuits.

The company is positioned to focus on the production, research and development, and innovation of diamond micropowder and diamond crushing materials; for a long time, it has always adhered to this goal and has become the mission of the company.
