CUTTING CONTROL SET UP EXAMPLES
FOR EXAMPLES #2 AND #3 PLEASE GO TO THE SAW AND FOLLOW STEPS 1-5 ON THE CHART:
Example #2
Material to be cut
-Round Steel Tube
SAE 4320
6" OD x 4" ID
-Hardened to 35 Rc (325 Bhn)
STEP 1
Effective Material Width: 4 1/2" (.75 x6)
STEP 2
Feed Force limit setting for 6" Diameter material 180 P.S.I.
STEP 3
Optimum blade pitch (TPI): 3/4 T.P.I.
Actual blade pitch on the saw: 4/6 T.P.I.
STEP 4
Optimum blade speed for 4 1/2" effective 225 ft/min
material width
Blade speed reduced by hardness factor: 225 ft/minx.60=135ft/min
STEP 5
Feed Rate for 3/4 TPI blade: 1.8 in/min
Feed Rate for 4/6 TPI blade: 1.8 in/minx.70=1.3in/min
(reduced by finer than optimum blade pitch factor,
