band speed.
Adjust the band speed, as needed to correct the trouble.
(2) If the band speed is correct, the pitch of the saw blade may be
incorrect.
Check the pitch of the saw blade, and select a blade of the
proper pitch, if required.
(3) If a blade with the proper pitch is in use, but saw band vibration
is still present, the choice of coolant may be incorrect. Select the proper
coolant to solve this problem.
(4) If the coolant being used is correct, it is possible that the feed
pressure is incorrect. Vary the feed pressure to see if this is causing the
trouble.
(5) Severe saw band vibration can occur if the work piece is not firmly
clamped to the table. If this is the case, adjust the clamps to solve the
problem.
(6) Worn or improperly adjusted saw guide inserts can cause saw band
vibration. Adjust or replace the saw guide inserts, as required.
(7) A worn saw guide backup bearing could be causing the problem.
Check
the saw guide backup bearing and replace it when needed.
(8) When the heavy work slide or the heavy work clamp is used, special
support must be used under the workpiece. If special support is not used,
saw band vibration could result.
