Here are some purchasing guidelines for metallographic grinding and polishing machines:
1、 Clearly define requirements and usage scenarios

For materials with high hardness, such as quenched steel, hard alloys, etc., the Rockwell hardness tester with HRC scale is usually chosen. Because the HRC ruler uses a diamond cone indenter and a larger test force, it can effectively measure such high hardness materials.

Metallographic sampling equipment usually includes the following types:
1. Metallographic cutting machine: used to cut large samples into sizes and shapes suitable for subsequent processing.

Metallographic embedding machine, also known as metallographic specimen embedding machine, is suitable for pressing thermosetting plastics on small metallographic specimens that are not shaped or easy to obtain.

Metallographic cutting machine is a device used for cutting samples in metallographic analysis.

Hardness is an important indicator for measuring the ability of metal materials to resist local deformation, especially plastic deformation, indentation, or scratches.
