Throughout the grinding and final lapping stages the objective has been to reduce pits and scratches to the smallest possible size. However no amount of grinding can produce a surface smooth enough or sufficiently transparent to meet the needs of a first-class telescope objective. Different techniques are By contrast attrition milling relies on a horizontal rotating vessel filled with a size-reduction solution. Treated to grinding media the materials tend to be turned into free-flowing spherical particles. This method which includes the ball mill can reduce 1 000 micron (20-mesh) particles of friable materials down to less than 1 micron.
