Clamping Shield Operation: Large Parts
The use of the clamping shield is optional. When performing calibration and testing on
small parts, it is advisable to remove the clamping shield.
The clamping shield is useful to eliminate fixturing of large parts that overhang the
anvil. Unlike other Rockwell scale systems, external supports and leveling fixtures are
not needed.
A second important use is to protect the indenter from impact and costly damage from
test specimens when the specimens are placed on the anvil. Also, clamped parts will
not shift under load which can break diamond indenters.
1. Snap or press in the clamping shield onto the stand around the indenter and
indenter shroud. Be sure the cut out portion of the bottom of the clamping shield
faces front (if there is a cutout section) The proper fit of the clamping shield into
the stand can be adjusted with the tension adjusting screw to maintain proper
tension for the clamping shield so it will stay in place while not being too tight to
remove. Adjust according to need.
2. Clamp the part firmly between the shield and anvil by raising the elevating screw
until the part is tightly fixed.
3. The part can now be tested like any other part.
4. Remove the part by dropping the elevating screw.
