Individual Force: The force is applied to each sample individually, eliminating planar grinding steps. However, the specimen plane is not fixed, which can lead to loss of flatness.
Central Force: Specimens are locked in a fixed plane, preventing rocking and improving flatness. However, 1-2 more planar grinding steps are needed with coarser abrasives.
