..., often called planar grinding , has the second goal of making all of the specimen surfaces coplanar. This process requires a special purpose machine because the stone must rotate at a high speed, ≥1500 rpm, to cut effectively. The stone must be dressed regularly with a diamond tool to maintain flatness...

The following procedure is recommended for this task: Grind the material protruding from the vise surface with 120-grit SiC paper until the excess sample is removed and it is flush to the aluminum vise surface. Do not use coarse paper, because damage...
