In April, everything is new, with the warm breeze blowing in the morning and the sunlight shining in the clouds. A recommended QMAXIS metallographic polishing consumables from the United States is for you. It's a bright spring day, bringing some new elements and new atmosphere to the laboratory.


Grinding and polishing are divided into two stages: smoothing and polishing. The purpose of grinding is to quickly remove rough surfaces left by cutting and obtain a smooth and fresh surface. Polishing, on the other hand, involves gradually increasing the surface roughness of the sample until it reaches the mirror level of optical observation.


Grinding: It is equivalent to rough machining in the sample preparation stage, requiring rapid grinding of coarse abrasive particles. It is usually recommended to use American QMAXIS silicon carbide metallographic sandpaper or diamond grinding discs.

     Silicon carbide metallographic sandpaper has strong toughness, good water resistance, uniform and dense distribution of silicon carbide particles, sharp edges, and high removal rate. By grinding the metallographic sample with it, the surface scratches are small, which is beneficial for subsequent polishing processes and can effectively shorten the sample preparation time.


Diamond grinding discs have high removal rate, good surface effect, long service life, and can replace sandpaper. The use of this metallographic grinding disc can quickly remove the surface layer and deformation layer of the sample, reduce grinding steps, shorten sample preparation time, and reduce the use of subsequent polishing cloth and polishing solution. Suitable for high hardness materials, such as cemented carbide, Thermal spraying coating and ceramics.


Polishing: It is the precision machining stage of sample grinding, which is very sensitive to the surface affinity of the material and the difficulty of material removal. It is usually recommended to use American QMAXIS metallographic polishing cloth, diamond polishing solution, or fine polishing suspension.


Metallographic polishing cloth is made of various high-quality polishing fabrics such as woven fabric, non-woven fabric, flocked fabric, chemical corrosion resistant synthetic materials, etc. It is hard and soft, and has different weaving properties such as velvet, short velvet, and long velvet. When combined with different polishing liquids such as metallographic rough polishing, medium polishing, and fine polishing, it has good polishing effect, does not shed hair or stain, and is suitable for surface polishing of various materials.

     Diamond polishing fluid is a high-quality diamond polishing agent commonly used in metallographic sample preparation, grinding, and polishing stages. It is non-toxic and environmentally friendly, and is suitable for both manual and automatic polishing. There are single crystal and polycrystalline; Water based and oil based; Various models such as concentrated and mixed are available to meet the metallurgical grinding and polishing needs of various materials. High removal rate and good polishing effect, making it an ideal polishing agent for metallographic grinding and polishing.

     In spring, the grass and trees will turn green, the flowers will bloom, the garden will be full of colors, and the spring light will be infinite. All beauty exists in an impartial and just manner. I wish you all an invincible success in the warm spring sun, and Mae Nomeri together with Liannengjia and the American QMAXIS metallographic polishing consumables!
