The grinding belt should be changed whenever
there is a noticeable change in grinding quality/
performance. You may also need to change grit
sizes for quick material removal or finer finishes.

This machine uses a 3" x 79" belt. Below is a
chart that groups abrasives into different classes,
and shows which grits fall into each class.
The general rule of thumb is to grind a workpiece
with progressively higher grit numbers. Avoid
skipping grits; the larger the grit increase, the
harder it will be to remove the scratches from the
previous grit.
Ultimately, the type of metal you use and your
stage of finish will determine the best grit types to
install on your grinder.
Belts are also made with different materials, and
your workpiece and intended operation will deter-
mine which belt material will produce the best
results for you. The chart below illustrates some
common belt materials and the situations that
they are most effective.
