The metallographic polishing cloth imported from QMAXIS in the United States has been widely used in China, and can be seen in metallographic laboratories in industries such as universities, research institutes, automotive, aviation parts manufacturers, electronics, and energy. Although not a internet celebrity, it is one of the star consumables for metallographic sample preparation. With it, metallographic sample preparation in scientific research, teaching, and quality control can achieve the desired appearance. What exactly does such a good metallographic polishing cloth look like? How to make application selection? Chaineng Metallographic Editor has completed the collection and organization. Please refer to the following for details.


The types of metallographic polishing cloth imported from the United States are mainly divided into two categories: lint free cloth and lint free cloth. The selection depends on the type of material to be processed and the requirements for final analysis purposes. The metallographic polishing cloth imported from the United States provides a variety of materials, weaving methods, and models of long and short velvet polishing cloth, which can meet every application requirement of metallographic analysis.

    Velvet free metallographic polishing cloth


As shown in the above figure, the velvet free metallographic polishing cloth is generally made of hard woven fabric, which has a tough texture and tight fiber structure. When using polishing agents for sample grinding and polishing, the abrasive particles of the polishing agent exist on the surface of the woven fabric, which can fully grind the sample surface with abrasive and improve the sample removal rate. This material's metallographic polishing cloth is more suitable for improving surface smoothness.


Velvet metallographic polishing cloth


As shown in the above figure, the material of the fluffy metallographic polishing cloth is very soft, and the surface has fluff. Some fluff is shorter, and some fluff is longer. Regardless of the type of fluff, compared to the hard woven fluff free metallographic polishing cloth, the abrasive particles of the polishing agent can penetrate deeper into the fluff, resulting in a relatively small removal rate and more flexibility. Therefore, although the polishing speed is slower, better sample surface quality can be obtained.

    Therefore, the applications of these two types of metallographic polishing cloths are different. Due to their good removal rate, non fluffy and hard metallographic polishing cloths are often used for coarse and medium polishing, while fluffy metallographic polishing cloths are used for final surface polishing and also for fine polishing, which can prepare very ideal sample surfaces.


The following list provides guidelines for selecting these metallographic polishing cloths

    With this selection guide, there is no need to ask anyone for the selection of metallographic polishing cloth imported from the United States. You can directly choose the appropriate metallographic polishing cloth according to the actual application.
