Sample Preparation - University College London

Sample Preparation. Grinding. Before you mount your sample in a sample holder, you should consider whether you need to grind or sieve it. Grinding (or even milling) may seem an obvious requirement if you want to achieve a fine powder. For some materials, e.g. many ceramic powders, grinding presents no problems and should always be performed.

EBSD Oxford Instruments - Grinding the Sample

The goal of Fine Grinding is to reduce damage and surface roughness of samples to a degree that is suitable for polishing. The choice of surface depends on the physical characteristics of the material to be ground and is critical. Rigidly fixed abrasives gives a flatter preparation result than when using surfaces with a shock absorbing backing.
