9. The following are important sawing precautions
which should be observes:
DO NOT feed work so rapidly that saw band
twisting or bowing occurs.
Reduce the feed force when cutting into an
opening to prevent saw band damage.
For future reference, keep a record of band
speeds, coolant application, etc. and other
settings for successful jobs.
Contour Sawing
1. Procedures for stock set-up and band speed
adjustment are the same as noted for production
sawing except that contour sawing of large, heavy
stock will require the use of optional air-operated
power feed or air-powered worktable and a heavy
gage saw band.
Starting Hole for Sharp Contour Cutting.
2. A hole is usually drilled in the stockpiece when a
sharp corner is to be cut, as shown in the illustration.
However, a corner may also be by-passed by cutting
a curve, and leaving the remainder to be notched
out later.
Internal Contours
1. To prepare for internal contour sawing: (a) Drill a
starting hole in the stock; (b) Run the saw band
through the hole; (c) Weld the saw band. Insulate
the saw band from contact with the stock or the
worktable will insure a better weld.
TYPICAL SAWING PROCEDURES

Internal Contour Sawing.
2. The diameter of the drilled starting hole is determined
by the size of the saw band being used. Use the
widest possible saw band for cutting the curve.
3. Attempting to cut too small a radius with too wide
a saw band will cause binding, and the lower
bandwheel may become grooved. The chart on
the Job Selector shows minimum radii cuts possible
with various saw band widths.
4. Radii chart recommendations are based on sawing
relatively thin stock. Consider these variations: (a)
Use a heavy gage saw band for heavy stock sawing;
(b) Use a narrower than recommended saw band
when sawing stock more than one (1) inch (25.4
mm) thick.
