If the feed rate is too high, machining is difficult and the chips are rough or torn.
Do not allow the tool bit to burnish the surface. If chatter problems occur, decrease
the feed rate and the speed. Then, make sure that the tool bits that you use are
sharp and are of correct type for the material. Stainless steel can harden during work.
Thus, cut stainless steel with a high enough feed, 0.08
–0.15 mm (0.003–0.006″) per
rotation, to cut under the hardened surface.
If the electric motor becomes overloaded, the motor shuts off.
However,
do not let
the motor overload. If possible,
cut
hard
materials with a low feed rate and speed.
After the pipe end is machined fully, stop rotating the handles and allow several
more turns of the spindle to improve the finish of the surface.
Then, use
the
ON/OFF
lever/switch to
turn
off
the
motor, and wait until the rotation stops. Rotate
the
handles
to the left to move the tool bits away from
the
pipe
end
to
at
least
3 mm
(0.12
″).
Then,
rotate
the
13 mm socket wrench to the left to loosen
the
draw
nut and release the
clamping, and remove the machine from the pipe.
Clean the pipe with petroleum ether.
Clean
the
machine
with a dry cotton cloth and no chemical agents.
