Water Cooling Metallographic Grinding And Polishing Machine Dust Collecting Abrasive Belt Grinder
iGrind-868 Abrasive band grinder was designed and manufactured according to the internationally advanced sample method, which uses the sander belt to polish so that we can change different size of the belt sander freely in accordance with requirements at random.
It can replace the grinding machine, pre-polishing machine, handy sandpaper so that each belt need just 1-2minutes to complete the operation. If spectrum samples in the spectrum is polished, we can not only save time and manpower but also save a lot of belts , as well as make sure safety, reduce the cost and make sure quality and increase the efficiency.
The machines apply to the enterprises, metallurgical industries as well as Materials R&D testing center, metallographic testing room and spetrum rooms and so.

After mounting, the specimen is wet ground to reveal the surface of the metal. The specimen is successively ground with finer and finer abrasive media. Silicon carbide abrasive paper was the first method of grinding and is still used today.
Many metallographers, however, prefer to use a diamond grit suspension which is dosed onto a reusable fabric pad throughout the polishing process. Diamond grit in suspension might start at 9 micrometres and finish at one micrometre.
Generally, polishing with diamond suspension gives finer results than using silicon carbide papers (SiC papers), especially with revealing porosity, which silicon carbide paper sometimes "smear" over.
After grinding the specimen, polishing is performed. Typically, a specimen is polished with a slurry of alumina, silica, or diamond on a napless cloth to produce a scratch-free mirror finish, free from smear, drag, or pull-outs and with minimal deformation remaining from the preparation process.
After polishing, certain microstructural constituents can be seen with the microscope, e.g., inclusions and nitrides.
If the crystal structure is non-cubic (e.g., a metal with a hexagonal-closed packed crystal structure, such as Ti or Zr) the microstructure can be revealed without etching using crossed polarized light (light microscopy).
Otherwise, the microstructural constituents of the specimen are revealed by using a suitable chemical or electrolytic etchant.
