BANDSAW OPERATIONS - OD1646 - LESSON 1/TASK 1
polishing, a 80 grain polishing band should be used at speeds between 850
and 1000 fpm.  For fine polishing, a 120 (or 150) grain polishing band can
be used at speeds between 850 and 1500 fpm.
(4) Polishing Feeds.
Feeds should be light for polishing operations.
Use a slow, sideways motion so that the polishing band will leave no marks
on the workpiece.
If the band does not remove the tool marks quickly, a
coarser polishing band should be used.
NOTE
The  procedures  used  for  polishing  using  bandsaw
machine model 2612-1M are presented here as an example
of
band
polishing
procedures.
Band
polishing
procedures are similar for all bandsaw machine models.
(5) Setting Up for Band Polishing.  Set up for band polishing with the
model 2612-1M bandsaw machine using these steps:
(a) Remove the table center disk.
(b) Mount the polishing band guide backup support to the lower adapter
as for filing.
(c) Lower the post to four inches from the table.  Then mount the band
polishing guide on the post and secure it with the two thumb screws.
(d) Occasionally, graphite powder should be rubbed into the guide fabric
to lubricate and to increase the life of the polishing bands.
(e) Mount polishing band to travel in direction of arrow printed on the
back side of polishing band.  The correct polishing band tension is the same
as that used for a 1/16 inch wide carbon saw blade.
(f) Install the special center adapter plate in the table.
(g) Do not use coolant with the polishing band.
