The abrasive is the particle responsible for grinding and cutting in the grinding wheel, and it usually has the characteristics of sharp and hard. The earliest abrasives can be divided into natural abrasives and artificial abrasives according to their sources. However, natural abrasives have been replaced by artificial abrasives in many applications due to their unstable performance.
In artificial abrasives, there is actually a distinction between general abrasives and super abrasives. The name Super Abrasive is particularly powerful when you hear it, below we will introduce you to super grit abrasives.
The term super abrasive comes from a polycrystalline diamond (PCD) material for cutting tools developed by General Electric (GE) in the 1970s. At the time, this very hard and brittle material was considered a major improvement in cutting tools.
At present, the industry generally refers to diamond and CBN (cubic boron nitride) as cbn powder, while WA (white alumina), A (brown alumina), GC (green silicon carbide), etc. are called general abrasive particles. In terms of hardness, diamond can be regarded as the highest grade of silicon carbide, while CBN is the highest grade of alumina.
The main reason why super abrasives can become a hegemon in the abrasives industry is that in order to improve the performance of key parts and components, the diamond powder manufacturers industry has continuously improved the structure of metal alloy materials, causing these materials to become harder and harder.
In order to polish another material, one material must be harder than it, so general abrasives gradually become weak, while super abrasives with higher hardness stand out.
