The process of metallographic grinding, usually consisting of grinding stones (wheels), grinding discs, sandpaper, thin films, etc. The abrasives are usually diamond, silicon carbide, aluminum oxide, zirconia, Boron carbide, etc. Cooling of grinding tools and samples is almost always done with water.
In most general experimental purposes, the above combination can completely complete the grinding of the sample. Obtain ideal edge protection, flatness, and surface quality.

However, when dealing with hard, very hard materials," I'm too difficult&# quo; The dilemma is that the sample preparation time is too long and the work efficiency is low; The extensive use of grinding consumables has led to an increase in sample preparation costs; The surface quality is slowly fading away.
At this point, I began to complain that the grinding and polishing machines were not purchased in place, and the metallographic consumables were purchased too low.
When the application engineer of Chain Metallography tells you that the metallographic grinding process is not only cooled by water, you will definitely ask" Are there any other tricks& Rdquo;
Yes, after chain energy metallography introduced the Acceleration Additive of QMAXIS into the materials laboratory in China, the grinding of Superhard material will not be difficult.

This is a complex alcohol amine compound that can be used in conjunction with various abrasives. The abrasive can be fixed on the surface of the grinding tool, or it can exist in the form of diamond, silicon carbide, and aluminum oxide micro powder. Grinding accelerators can increase the dispersion ability of abrasives and give them adhesive viscosity, preventing them from being thrown out by centrifugal force like pure cooling water, thus improving the friction between the abrasives and the sample. At the same time, the chemical action of the grinding accelerator on the sample effectively promotes the surface hydration of the material, and in combination with the physical and mechanical grinding of the abrasive, the material removal rate is improved. The layer of grinding accelerator water film between the grinding tool and the sample effectively prevents direct contact grinding, avoiding scratches on the surface of the sample, and the surface effect is significantly better than water cooling.
It is not difficult to imagine that the basic components such as thermal conductivity and anti-corrosion are indispensable in the compound of grinding accelerator, which provides sufficient guarantee for the successful preparation of the sample.
