Water Cooling XGrind-319 Single Disc Grinding Polishing Machine with Fixed Double Speed
Catalogue Download: Grinding and Polishing Machine XGrind-319
XGrind-319 single disc Metallographic Grinder and Polisher is suitable for carrying out pre-grinding, fine grinding and polishing against metallographic specimens.
Since the machine has fixed double speeds 150rpm and 300rpm, which favors the machine with wide applications.
XGrind-319 is equipped with cooling system that can cool down the specimen during pre-grinding so as to prevent overheating and damaging the metallographic structure .
XGrind-319 is convenient and on the safe side .It is an ideal option for the lab .of factories, science and research institutions and universities.

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.
