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. 

—— Dalius Skinulis

The Measurements are good for Brinell Tester HBST-3000.

—— Sun Chull Kim

Hey, the hardness tester iVick-484ST was installed last week and works well, thanks for the professional support.

—— Sabinian Smith

I am glad to inform you that the installation of the SHB-3000C Brinell hardness tester has been finished successfully. I would like to thank you!

Differences Between Chemical Polishing and Mechanical Polishing

 

Chemical polishing is essentially different from mechanical polishing

Chemical polishing is the process of dissolving the tiny convexities on the surface to be polished first, improving the roughness of the metal surface and obtaining a smooth and bright surface.

 

Mechanical polishing is the process of removing the convexities on the surface to be polished by cutting, abrasion or plastic deformation to obtain a smooth and bright surface.

 

The two polishing methods have different effects on the metal surface, and many properties of the metal surface are changed, so chemical polishing and mechanical polishing are essentially different.

 

Due to the limitations of mechanical polishing, metal workpieces such as stainless steel cannot perform their due functions. These problems are difficult to solve. Since the emergence of stainless steel electrolytic polishing technology, the problems that are difficult to solve in mechanical polishing have been solved to a certain extent, and the advantages are obvious. However, electrolytic polishing still has many disadvantages.

 

Comparison between chemical polishing and electrolytic polishing

 

Chemical polishing: immersing the metal in a special chemical solution composed of various components, and the metal surface is naturally dissolved by chemical energy to obtain a smooth and bright surface.

 

Electrolytic polishing is to immerse the metal in a special chemical solution composed of various components, and use the current energy to dissolve the metal surface anode to obtain a smooth and bright surface.

 

Chemical polishing is just an immersion operation and is simple to operate. Electrolytic grinding and polishing requires large-capacity direct current, reasonable setting of current counter-electrodes, precise control of current and voltage, complex operation process, difficult quality control, and some special workpieces cannot be processed.
