BANDSAW OPERATIONS - OD1646 - LESSON 2/TASK 2
(1) The upper wheel may not be aligned correctly, so that the band does
not track on the center of the wheel tire.  Adjust the track of the band, as
required.
(2) Too much coolant or the wrong type of coolant can cause the band to
slip off the wheel tires.
(3) The initial machine alignment may be wrong.  When this is the case,
refer to TM 9-3419-227-10, page 3 for the procedure needed to solve the
problem.

Troubleshooting  the  Malfunction:  EXCESSIVE  INSERT  AND  BLADE
WEAR.
When there is excessive insert and blade wear, make these checks:
(1) Check to see if the inserts are adjusted too tight on the blade.
Make adjustments as needed.
(2) Check to ensure that the band is being lubricated properly.
High
band speed causes friction.  Coolant should be used to lubricate the band.
(3) Check to see if the rollers on the roller guides are adjusted too
tight on the blade.  Loosen the roller guides, if needed.
(4) The  chip  brush  may  be  worn,  or  may  not  be  adjusted  properly,
allowing the chips to stay on the wheel.  Check for this condition, and make
the necessary repairs.
n.
Troubleshooting the Malfunction: FILE BAND BREAKS.
When the file band
breaks, two conditions could be the cause:
(1) The feed force may be too high.
Adjust the feed force to solve the
problem.
(2) The wrong type of file band may be in use.  Make sure that a file
band of the proper shape, width, and number of teeth is being used for the
material in the workpiece.
o.
Troubleshooting When There is a POOR FINISH FROM BAND FILING.  A poor
finish  from  band  filing  could  be  the  result  of  any  of  the  following
conditions:
