For a deformation- and relief-free polishing result, choosing the right polishing cloth is crucial. The cloth material and texture (silk, artificial silk, synthetic fibers, wool fabric, felt, flocked or foamed synthetic fabrics) and the resulting impact elasticity play a decisive role in the selection of the suiting polishing cloth. The fastening systems (GALAXY metal disc with magnetic foil or GALAXY X-Tap) also differ, and can influence the polishing result. The GALAXY polishing cloths, optimized with the QPREP anti-slip backing, withstand high shear forces even under high contact pressures and fully loaded sample holders, ensuring a stable polishing process at all times.
At the beginning, pre-polishing, polishing cloths with a low resilience (hard cloth material) are selected, as these support the retention of edge sharpness. In comparison to the further polishing steps, a higher material removal is achieved during pre-polishing due to longer polishing times.
Polishing cloths with different resilience are used for intermediate polishing. The objective of the polish and the material to be polished are always the determining factors for the selection of a suitable polishing cloth.
Final polishing is performed on polishing cloths with a high resilience with short polishing times to avoid relief formation. Final polishing can either be done with diamond suspensions (3 μm - 0.5 μm) or, for the highest demands for analysis, by using fine polishing suspensions (oxide polish 0.1 μm - 0.05 μm) or (alumina 1 μm - 0.3 μm).
The selection of QPREP polishing cloths offers a suitable cloth for every polishing step, which, with the matching QPREP diamond suspension, ensures excellent polishing results.
