6. Intermittent dressing is becoming more acceptable. Because the material removal per pass is so great in creep-feed grinding, aluminum-oxide wheels used in this process tend to require continuous dressing. A dressing wheel applied to the grinding wheel as it is grinding keeps the wheel sharp at all times.

In the case of graphene, when the ions hit the surface at a high temperature, single layers of graphene are separated from the 3-D graphite structure. A centrifuge, which spins samples quickly to separate them based on density, can then be used to separate the remaining graphite from the graphene produced and ensure high purity.
