The first grinding step for accurate sample preparation is pre-grinding the material to remove irregularieties like embedded edges and to produce the required planar surface. The Belt Grinder Jade 700 is ideally suited for manual deburring and pre-grinding of materials. The Saphir 375 model is an automated stone grinder with touchscreen operation and measurement of the removed layers.
