Friends in the industry may feel a bit strange when they see the title, because the selection of metallographic polishing cloth mainly depends on the material characteristics and sample preparation objectives of the metallographic sample, and has little to do with the metallographic polishing machine.


Yes, indeed. However, in the daily work of Lianneng Metallographic Editor, we often encounter some purchasing girls or brothers who do not understand the technology. In order to help these friends complete the procurement work smoothly, today Lianneng Metallographic Editor is here to talk to these friends about the selection of metallographic polishing cloth.


It is not wrong to say that the selection of metallographic polishing cloth has nothing to do with the metallographic polishing machine. The size of the grinding disc of the metallographic polishing machine is one of the main parameters for selecting metallographic polishing cloth. The diameter of the polishing cloth must be consistent with the size of the grinding disc of the metallographic polishing machine. If the size is too small, it cannot be used; If the size is too large, engineers need to use scissors to reduce the excess part, which can be used, but it will cost more because the price of metallographic polishing cloth with larger size is higher than that with smaller size. In addition, the engineer has added another task of cutting small polishing cloths, which is a bit troublesome to be honest with. Perhaps this is the only relationship between the selection of metallographic polishing machines and polishing cloths. So, please remember this point, when choosing polishing cloths, all you need to do is have the same diameter and size.

    There are many types of materials used for polishing cloth, and taking QMAXIS imported metallographic polishing cloth from the United States as an example, there are over ten types of materials. Specifically, these imported metallographic polishing fabrics are high-quality polishing fabrics with high material removal rate, excellent surface finish, long service life, and high cost-effectiveness. They are suitable for various types of polishing fabrics made of different materials, and all come with adhesive backing. There are three main categories suitable for rough polishing, medium polishing, and fine polishing.


Coarse polishing cloths include UltraPad, UltraPol, and TexMet P


The polishing cloths used in polishing include Nylon, TexMet C, TriDent, VerduTex, VelTex, WhiteFelt, PoliCloth


Polishing cloths for precision polishing include: MicroCloth, MicroFloc, MasterTex, ChemoMet


The specific selection should be based on the material and preparation purpose. The editor will compile a selection table for friends to refer to.

    If you feel that the selection table for this metallographic polishing cloth does not yet allow you to figure out how to choose, please contact the application engineers of Chain Metallography directly. They are always available to provide you with consulting services, which are free of charge. Don't worry about consulting.
