BANDSAW OPERATIONS

BANDSAW OPERATIONS - OD1646 - LESSON 1/TASK 1polishing, a 80 grain polishing band should be used at speeds between 850and 1000 fpm. For fine polishing, a 120 (or 150) grain polishing band canbe 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 markson the workpiece. If the band does not remove the tool marks quickly, acoarser polishing band should be used.NOTEThe procedures used for polishing using bandsawmachine model 2612­1M are presented here as an exampleof band polishing procedures. Band polishingprocedures are similar for all bandsaw machine models.(5) Setting Up for Band Polishing. Set up for band polishing with themodel 2612­1M bandsaw machine using these steps:(a)Remove the table center disk.(b) Mount the polishing band guide backup support to the lower adapteras for filing.(c) Lower the post to four inches from the table. Then mount the bandpolishing guide on the post and secure it with the two thumb screws.(d) Occasionally, graphite powder should be rubbed into the guide fabricto lubricate and to increase the life of the polishing bands.(e) Mount polishing band to travel in direction of arrow printed on theback side of polishing band. The correct polishing band tension is the sameas that used for a 1/16 inch wide carbon saw blade.(f)(g)Install the special center adapter plate in the table.Do not use coolant with the polishing band.48
