7. MAKE PROPER TOOTH SELECTION
For maximum cutting efficiency and lowest
cost per cut, it is important to select the blade
with the right number of teeth per inch (TPI) for
the material being cut. The material size and
shape dictate tooth selection.
TOOTH
SELECTION
You need to consider:
The width of the cut - That is, the distance in
the cut that each tooth must travel from the point
it enters the work-piece until it leaves the work-
piece, and
1.The shape of the work-piece.
Squares, Rectangles, Flats
(Symbol : ■)
Locate the width of cut on the chart.
(Inches on the outer circle and
millimeters on the inner circle.) Select
the tooth pitch on the ring marked with
the square shape which aligns with
the width of cut.
EXAMPLE: 6" (150mm) square, use a
2/3 Vari-Tooth.
Round Solids (Symbol : ●)
Locate the diameter of your work-
piece on the chart. Select the tooth
pitch on the ring marked with the
round shape which aligns with the size
of stock you are cutting.
EXAMPLE: 4" (100mm) round, use a
3/4 Vari-Tooth.
Tubing, Pipe, Structural ( Symbol :
O H ^ )
Determine the average width of cut by
dividing the area of the work-piece by
the distance the saw blade must travel
to finish the cut. Locate the average
width of cut on the chart. Select the
tooth Ditch on the ring marked with
the tubing and structural shape, which
aligns with the average width you are
cutting.
EXAMPLE: 4"(100mm) outside diameter,
3"(75mm) inside diameter tubing.
4"(100mm) OD =12.5 sq.ln. (79cm2)
3"(75 mm ) ID = 7.0 sq.ln. (44cm2)
Area = 5.5 sq.ln. (35cm2)
5.5 sq.ln. (35cm2) / 4" (100mm)
distance =1.38(35mm) average width
1.38" (35mm), use a 4/6 Vari-
Tooth
NOTE: The band speed and cutting
rate recommendations presented on

.
9-5. ADJUSTING BLADE TENSION AND BLADE TRACKING
To tension the blade, turn the blade tension handle (fig. 1)(A)
clockwise. The scale is graduated to indicate blade tension of
20,000, 30.000 and 35,000 pounds per square inch (psi). For
carbon blades, the blade should be tensioned at 20,000 psi. For bi-
metal blades (similar to the one supplied with the machine), the
blade should be tensioned at 30,000 or 35,000 psi. Always release
blade tension at the end of each working day to prolong blade life.
Make sure the blade is tensioned correctly before checking or
adjusting tracking. The blade is tracking properly when the back of
the blade is just lightly touching the wheel flanges of both wheels
while the machine is running.

9-8. BLADE AND COOLING SYSTEM
The use of proper cutting fluid is essential to obtain maximum
efficiency from a band saw blade. The main cause of tooth failure
is excessive heat build-up. This is the reason that cutting fluid is
necessary for long blade life and high cutting rates. cutting area
and blade wheels should be kept clean at all time.
The rate of coolant flow is controlled by the stop valve lever (A)
(fig. 4), which directs the coolant onto the blade. The lever (A) is
shown in the off position.
9-9. OPERATING THE TRU-LOCK VISE SYSTEM INSTRUCTIONS
