Metallographic grinding and polishing insight
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 and µm
