BANDSAW OPERATIONS - OD1646 - LESSON 2/TASK 2
five conditions, and make corrections or adjustments, as needed:
(1) The saw guide inserts may be worn.
Readjust them, as needed.
(2) The saw band speed may be too low.
(3) The saw band pitch may be too coarse.
(4) The feed may be too heavy.
(5) Vibration  could  cause  this  condition.
The  troubleshooting
procedures used to solve vibration problems can be found in paragraphs 4b
and 4c, beginning on page 75.

Troubleshooting the Malfunction: PREMATURE DULLING OF SAW BAND TEETH.
Premature dulling of the saw band teeth may be caused by any of these
conditions:
(1) The saw band must be broken in on the first few cuts by using a
reduced feed pressure and speed.  If the saw band is not broken in this way,
premature dulling of the saw band teeth can occur.
(2) The band speed may be too high causing abrasion.
Reduce the speed,
as needed.
(3) The saw band pitch may be too coarse.
Choose a band with a finer
pitch.
(4) The feed pressure may be too light.
Increase the feed pressure as
needed to solve the problem.
(5) The coolant may not be covering the saw band.
Make adjustments, as
needed.
(6) The cutting rate may be too high.
(7) There may be a fault in the material being cut, such as a heavy
scale, inclusions, or hard spots.
(8) Saw  band  vibration  can  cause  premature  dulling  of  the  blade.
Troubleshooting procedures to solve saw band vibration problems can be found
in paragraph 4c, beginning on page 75.
