Mechanical preparation:

Mechanical preparation is a particularly common method for preparing metallographic samples for microscopic examination. The specific requirements for preparing surfaces depend on the specific type of analysis or inspection. The prepared sample can achieve a more ideal finish, true structure, or can be stopped after the surface meets specific inspection requirements.

The goal of preparation: The basic process of mechanical sample preparation is to use fine grinding particles to finely machine the material, remove the material from the surface, and achieve the desired results. There are three methods for removing materials: grinding, polishing, and precision grinding. These three methods differ in introducing surface deformation of the sample.

All structural elements must be retained

The surface must not show scratches or deformation

Impurities cannot be introduced on the surface of the sample

The sample must be flat and have high reflectivity

Should obtain the optimal sample unit price

All preparations must be 100% reproducible
