Figure 7 Specimen mounts.
The specimen mount for use in conjunction with the small, 10-mm diameter
wheel has a conical shape to prevent fouling of the grinding wheel axle assem-
bly.
The specimen mount for the large, 20-mm diameter wheel is a simple disc.
Note: The specimen mounts should be periodically checked for smoothness and
flatness. This may be done either with the stereo microscope or a free-standing
dial indicator.
