Installation
2 Dimple Grinder User’s Guide
2.0 Installation
The Dimple Grinder operates from the standard mains voltage with no other
external services or utilities necessary. However, for reproducible high-quality
results, the Dimple Grinder must sit on a flat, vibration-free surface in a rela-
tively clean environment.
The Counterweight is packed separately and should be attached by screwing it
into position on the Platform. After installation, the zero point of the Counter-
weight scale should be checked (see Section 5.2).
3.0 Description
The base (body) of the Dimple Grinder (see Figure 1) holds the Control Panel,
the Micrometer Drive, the Magnetic Turntable with motor drive, the Raise/
Lower Cam, and the Transmission Illumination system. On top of this base sits
a pivoted Platform containing the Grinding Wheel assembly, the analog Dial
Indicator, and the Counterweight. The Platform, when in the vertical position, is
held in place by a magnetic latch (at the rear). With the Platform raised, a stereo
microscope can be mounted over the Magnetic Turntable for specimen viewing.
