SMART CUT: Checking and Adjusting the Feed Rate
During the CUTTING CYCLE, the IsoMet 4000 will monitor the load that is applied to the blade. If an
overload condition occurs, the IsoMet 4000 will automatically decrease the FEED RATE to maintain an
optimum cutting condition.
This automatic function is the SMARTCUT feature and when in use, is displayed in the center of the LCD
Screen. If the load is still too high and the blade stalls, a warning indicating BLADE PINCH will display
and the saw will power OFF in approximately 20 seconds.
To change the FEED RATE during operation, press the SCROLL button until the value under FEED
RATE is highlighted. Press the DECREASE or INCREASE buttons to select the desired rate in the range
of .05 in/min [1.5 mm] to .75 in/min [19 mm].
Blade Dressing
Blade dressing exposes the abrasive grain to ensure free cutting. New wafering blades should be
dressed several times and older blades dressed as required based on the specimen material properties
.
The IsoMet 4000 is shipped with the Automatic Blade Dressing attachment adjusted for a
7-inch diameter blade. When a different diameter blade is installed, the Automatic Blade Dressing
attachment must be readjusted.
