1.0 Product Description
1.1 General Description
The PENTA 7500 is a single belt hand grinder for coarse grit specimen planarization. A unique
benefit of the PENTA-7500 belt grinder is the fixture for planarizing specimen mounts. This is
very important for maintaining a square mount for automated polishing machines.
Another benefit is a high 0.75 horsepower motor that is capable of running the belt with enough torque to
remove material from any sample.
A rinse station also allows for the sample to be easily cleaned after grinding.

Preparation Stage
Purpose
Initial Documentation
•Document the initial condition of the sample
•Map the sample surface
•Highlight the area of interest
Sectioning/Cutting
•Reduce the size of large samples
•Reduce sample size closest to the area of interest
Rough, or Planar
Grinding
•Obtain a planar surface
•Remove sectioning damage
•Approach the area of interest
Rough Polishing
•Remove all the subsurface damage and microstructural
damage produced during cutting and rough grinding
(superficial scratches may still be present after this step)
Final Polishing
•Generally, more for cosmetic purposes than for removing
microstructural damage. In most cases, this stage should be
minimized to avoid over polishing and distorting the
microstructural features
Etching
•To enhance microstructural feature such as grain boundaries,
grain size, phase differences, ect.
Examination
•A variety of examination techniques are used in
metallography, including optical microscopy, electron
microscopy, and hardness testing
4.4 Metallographic Specimen preparation Basics
Typical metallographic specimen preparation consists of the following steps:

The PENTA 7500 requires very minimal maintenance. However, to increase the life of
the grinder, it is suggested that the unit be rinsed after use.
5.2 Cleaning Inside Cabinet
The inside of the cabinet where the belt mechanism is located should be cleaned and
dried to avoid possible corrosion. It is advised to leave the side panel open when
finished using the machine to reduce humidity and allow air flow. Do not use chemical
or cleaning abrasives on the inside of the cabinet.
5.2 Cleaning Outside Cabinet
The outside cabinet should be cleaned occasionally with a moist cloth. Do not use
any chemicals or cleaning abrasives while cleaning.
