Cut and Etch Welding

There are several ways you could cut a sample for a macro etch test. Chop saw, hand grinder with cutting disc, band saw etc. The smoother the cut, the less grinding and polishing is needed. Sanding and Polishing Once cut, you should be able to start the sanding with 50- 80 grit .

Metallographic grinding and polishing insight Struers

Fine grinding produces a surface with little deformation that can easily be removed during polishing. Because of the drawbacks with grinding papers, alternative fine grinding composite surfaces are available, in order to improve and facilitate fine grinding, A high material removal rate is obtained by using grain sizes of 15, 9.0 and 6.0 µm.

Metallographic Abrasive Grinding

Note for SiC grinding papers, as the abrasive grains dull and cut rates decrease, increasing grinding pressures can extend the life of the SiC paper. Higher grinding/polishing pressures can also generate additional frictional heat which may actually be beneficial for the chemical mechanical polishing (CMP) of ceramics, minerals and composites.
