Customer Reviews
The touch screen micro vickers hardness tester has been installed a few weeks ago, everything is OK. Thanks for your advice and excellent service.

—— Mr. David Chambers

Thanks for the fast delivery and our customer is very satisfied for the rockwell hardness tester, and hope more orders soon.

—— Neil Renato

After we visited the customer, they finally decided to purchase Brinell hardness tester iBrin-413Z, now we have installed the unit at customer’s site,

—— Fermin Lee

Thank you for the indenters (diamond  cone 120 degrees). We recently got it and already tested it. Indenters  are good as we expected.

Metallographic Grinding Automatic Polishing Machine With Polishing Head

 

Brief Introduction:

 

iGrind-826 is a double disc automatic grinding/polishing machine, apply advanced micro processor, makes grinding disc and polishing head realize stepless speed, the setting of pressure and time is convenient and intuitive.

 

Operator just needs to replace grinding disc, sandpaper and polishing fabric can start grinding and polishing operation.

 

This unit comes with water cooling device and washing nozzle, used to cooling specimens during grinding, to avoid overheating damage metallographical structure. washing nozzle can wash away the grinding scraps thoroughly.

 

This unit is suitable to do automatic rough grinding, finish grinding, rough polishing and finish polishing, with the features as follows:

 

1, Rotation direction is exchangeable

2, Quick replace of grinding/polishing discs

3, Multiple specimen holders

4, Pneumatic single point loading

5, Automatic Grinding consumables deliver (optional)

6, Stable rotation, safety, reliability, low noise

7, Cast aluminium base enforced the rigidity

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.
