iqualitrol Grinding and Polishing Machine XGrind-316

Brief Introduction:

XGrind-316 grinding-polishing machine is a double-speed double-drive desktop, applicable to rough grinding, fine grinding and polishing of metallographic sample.

XGrind-316 has stepless speed of 50-600rpm to widen its application. and has a cooling device to cool the sample during grinding and polishing, thus preventing the damage of the metallographic structure caused by overheat of the sample.

XGrind-316 is easy to use, safe and reliable, an ideal sample preparation equipment for the labs of plants, research institutes and universities and colleges.

Technical Specifications:

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.

Application:

MP-2D metallographic sample grinding and polishing machine is a two-speed double-drive desktop machine, which is suitable for rough grinding, fine grinding and polishing operations on metallographic samples.

The machine has two speeds of 600 rpm and 300 rpm, which makes the machine more widely applicable and is an indispensable equipment for users to make metallographic samples. The machine is equipped with a cooling device, which can cool the sample during grinding and polishing to prevent the metallographic structure from being damaged due to overheating of the sample.

The machine is easy to use, safe and reliable, and is an ideal sample preparation equipment for factories, scientific research units and laboratories of colleges and universities.

It is suitable for automatic sample preparation in the process of rough grinding, fine grinding, rough polishing to fine polishing of metallographic samples. It is an ideal sample preparation equipment for enterprises, scientific research units and laboratories of colleges and universities
