Single specimen preparation is usually started with fine grinding. Fine grinding must remove the deformation existing from cutting or plane grinding and produce a surface that is ready for polishing. Choosing the correct fine grinding materials is vitally important to ensure fast and economical preparation. Struers offers a wide range of options for fine grinding, allowing for the preparation of all materials, regardless of hardness and ductility.
Traditionally, fine grinding is carried out in several steps with SiC paper. This method is particularly common within manual preparation. The most efficient fine grinding procedure, however, involves diamond as abrasive. On MD-Allegro, MD-Largo or various fine grinding cloths, abrasive is applied during the process. The selection of cloth resilience will have a dramatic effect on such factors as the speed of material removal, planeness and edge retention. Furthermore, abrasive grain size can be precisely tailored to the material requirements.
