Grinding is usually a two-step process. The first step in the grinding process is known as plane grinding. Plane grinding is the process of making the entire surface similar. For example, if the sample surface had several raised areas, plane grinding would flatten those areas to a similar condition as the rest of the surface. The …

If the holder is positioned too close to the centre, most unfavourable grinding and polishing dynamics will be the result (sketch 1). The positioning as shown in sketch 2 is ideal: The sample holder should extend slightly beyond the edge of the working wheel, approximately 5 to 10 mm. With this setup, the samples still move on the cloth!
