3.8 Specimen Mounts
The specimen mount is held in position by a centering ring on the Magnetic
Turntable. To accommodate the various diameter grinding and polishing
wheels, three different, appropriately-sized mounts are available to insure the
proper grinding-wheel axis orientation (see Figure 7).
The standard mount, for use with the standard 15-mm diameter wheel, is cylin-
drical in shape and made of stainless steel. Opaque specimens are normally
mounted on the stainless-steel mount. For transparent specimens or for materi-
als that become transparent when very thin, such as silicon, a glass (pyrex)
specimen mount is available that allows the progress of thinning to be moni-
tored in transmitted light.
