The following table shows the possible answers to a number of
common cutting questions:
Optimising the Cutting Results
Objective
How to achieve it
Better surface
quality
Use lowest recommended feed speed and no specimen
holder rotation.
Lower wheel wear Use the lowest recommended feed speed and no specimen
holder rotation. This is especially important when using resin
bonded wheels and all abrasive cut-off wheels.
Problems with
abrasive cut-off
wheels?
Abrasive cut-off wheels should not be used outside their
recommended feed speed range. At lower than
recommended feed speeds they will produce irregularly cut
surfaces. At higher feed speeds excessive wheel wear will
occur, along with increased risk of wheel breakage.
Flatter samples
Use primarily low feed speeds, highest recommended wheel
speed, largest possible flanges and no specimen holder
rotation.
The initial kerf is especially critical. If the initial feed speed is
too high the wheel will bend and start cutting at an angle.
Such a cut will never end up flat.
Better parallelism
Use the lowest recommended feed speed.
Faster cutting
Orientate the sample so that the wheel will cut the smallest
possible cross-section and then use maximum
recommended feed speed.
