Notes on Sawing
The factors affecting cutting performance are: the blade, tooth pitch, the work/size of material being
cut, blade speed and feed. Contact Elliott for assistance with selecting the proper blade for sawing
jobs. All blades should be straight, have sharp teeth, and be “broken in” to obtain good cutting
performance and blade life.
Breaking in the Blade
Breaking in your blade is done by slowing your feeds and speeds down on the first 8”-10” of the cut
(about 5-8 minutes), which burnishes the blade and extends blade life.
NOTE
: CUTTING AT TOO HIGH OF FEEDS AND SPEEDS WITH A NEW BLADE CAN DECREASE THE
QUALITY OF CUTTING AND SHORTEN BLADE LIFE. DO NOT START A NEW BLADE IN AN OLD CUT.
Good Cutting Performance
Every cutting situation has special characteristics requiring some experimentation to determine which
blade, speed, and feed will achieve the most satisfactory results. Cutting charts indicate a good
starting point, but must be modified by direct experience if optimum performance is desired. Here are
some helpful pointers for adjusting speed and feed for good cutting performance.
• Watch for excessive “smoke” from coolant indicating heat in the cut, which could
damage the blade directly or work-harden the material being cut.
• Watch for excessive vibration or chatter marks on the cut off piece indicating
possible damage to saw teeth by “hammering”.
• Check the cut off piece for flatness. A dull blade or excessive feed will cause
“cutting in” or “cutting out”.
• Inspect the blade for worn or dubbed cutting edges. Avoid cutting conditions,
which allow chips to “weld” to saw teeth.
• When experimenting, gradually increase speed, then feed, by small amounts
until adverse effects are noted; then reduce speed to a reasonable level for
continuous cutting. Remember that speed and feed must be “balanced” to
keep cutting a good chip
