Brief Introduction:

In the process of metallographic sample preparation, polishing is a main procedure. After polished, the sample surface is like a mirror.

XGrind-301 metallographic sample polishing machine is a classic polishing equipment with steady running,small noise, convenient operation and maintenance.

XGrind-301 meets the polishing requirement of all kinds of materials, and suitable for factories and mines enterprises,colleges and universities,scientific research institution.

Technical Specifications:

Polishing discs are covered with soft cloth impregnated with abrasive diamond particles and an oily lubricant or water lubricant.

Particles of two different grades are used: a coarser polish - typically with diamond particles 6 microns in diameter which should remove the scratches produced from the finest grinding stage, and a finer polish – typically with diamond particles 1 micron in diameter, to produce a smooth surface.

Before using a finer polishing wheel the specimen should be washed thoroughly with warm soapy water followed by alcohol to prevent contamination of the disc. The drying can be made quicker using a hot air drier.

Mechanical polishing will always leave a layer of disturbed material on the surface of the specimen. Electropolishing or chemical polishing can be used to remove this, leaving an undisturbed surface.
