The FF 206 with a single-
point tool will allow you to
bevel heavier walled pipe
than is possible using the
SDB 103 with form tooling.
Using the FF 206, you can bevel a pipe face with a single-
point tool. As the machine rotates and the radial feed
advances the tool automatically, turn the manual feed han-
dle counter-clockwise to withdraw the tool and create the
bevel profile. Follow the procedure below, using the infor-
mation in Table 5.
1.
Calculate the starting axial position (cutting depth) on
the O.D. of the pipe. Use the “Tangent” value in
Table 5 for the bevel angle you are performing, and
refer to the drawing in Figure 5-43.
EXAMPLE
:
T = 0.75”
A = 20°
D = tangent(20°) x 0.75”
= 0.364 x 0.75” = 0.273”
Figure 5-43. Use the pipe thickness and the bevel
angle to calculate the starting depth of cut (D). Refer
to Table 5 for tangents of common bevel angles.
A cutting depth of 0.300” (7.6
mm) is possible under ideal
circumstances. You may
need to cut smaller passes if
the pipe material is especially
hard or if you are cutting a
coarse finish.
2.
The maximum depth you can cut at one time is about
0.300” (7.6 mm). If the number you calculated for D is
greater than that, divide D by 0.300 (or 7.6 if metric)
to determine the number of passes to make.
Figure 5-44. Cut multiple passes if necessary.
