Many people often ask during the polishing process, “Should I use sandpaper for this surface, or opt for a specific grade of diamond paste abrasive?” When it comes to selecting polishing materials like diamond paste or the grit number of a grinding wheel, how do we determine which grit number can achieve the desired result? Let big data and statistical analysis provide you with the answer.
There are many types of grinding wheels and tools, with various shapes and sizes. Depending on the abrasive material, bonding agent, and manufacturing process, each grinding wheel has a specific range of applications. An incorrect choice can directly affect machining accuracy, surface roughness, and production efficiency. Therefore, when performing grinding operations, it is essential to select the appropriate grinding wheel based on the specific situation. How can we correctly choose a grinding wheel? Here’s a summary of commonly used grinding wheels in machining to help you make informed choices.
Diamond is one type of superhard material and cubic boron nitride is another. The two kinds of superhard materials after a series of machining and processing procedures can be made into a variety of tools and directly with them into a variety of functional devices, collectively referred to as superhard material products.
Mirror finishing refers to the process where the surface of a workpiece is polished to the point where it can reflect images like a mirror. This level of finish signifies exceptional surface quality, providing products not only with a high “aesthetic value” but also reducing notch effects, thereby extending the fatigue life of the workpiece. It holds significant importance in many assembly and sealing structures.

Fluorine rubber and nitrile butadiene rubber were modified by using purified and post-blasted synthetic products (nano-diamond black powder and gray powder). The study shows that although the black powder can increase the hardness of rubber, but the tensile strength and elongation at tear decreased. Nano diamond powder gray powder added to the fluorine rubber, the …
In 1992, Yashchenko and others in the United States used powder metallurgy to make a new type of anti-wear material, which is made by mixing copper-zinc and copper-tin powders with nano-diamond powder in a certain proportion by compaction, and then sintered in hydrogen gas. This new material can be used in internal combustion engine cylinder …

鑽石膏是常用的拋光劑，如使用得當可獲得最佳的效果。
拋光用的工具，從不同類型的纖維到粘墊品，不同硬度的材質都很適當。如尼龍、紙、天鵝絨、棉花等。
拋光時需留意：
a．拋光應在一個無塵、通風處進行，因堅硬的塵粒易沾附於鑽石膏上會損毀快要磨好的表面；
b.每一個拋光工具都應僅用於一種鑽石膏，並注意防塵：
