Catalogue Download: iqualitrol Grinding and Polishing Machine XGrind-309
iqualitrol Single disc XGrind-309 grinder polisher is suitable for pre-grinding, grinding and polishing metallographic specimens. Since the machine is speed-adjusted by a transducer, it can get 50-1000rpm , which favors the machine with wide applications.
The machine is equipped with cooling system which can cool down the specimen during primary grinding so as to prevent overheating and damage the metallographic structure .
Featuring easy operation and reliable performance, it is an indispensable device for the factories, research institutions and college labs to prepare metallographic specimen.

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.
