There are two accepted methods of tube cutting: one using the
standard tube cutting tool shown in Figure 2-4, the other using a
After completion of the tube cutting in either of these
processes, remove all residue produced. To do this, ream the end of
the tube slightly and flush the entire piece of tubing thoroughly.
These methods are discussed in detail further in this text.
Standard Tube-Cutting Tool.
Standard Tube-Cutting Tool. The ideal method of cutting tubing is
with a standard cutting tool.
The tube is slipped through the
cutting tool at a right angle, and the cutting wheel is adjusted
against the tube. Take care not to force the wheel against the tube
too tightly, as this forces the tube out-of-round. While the tool is
being rotated, the cutting-wheel feed must be tightened a little with
each turn until the wheel has cut through the tube. The tube cutter
must be rotated in only one direction, with its handle being swung in
the same direction that the opening faces. When properly used, this
tool leaves a smooth end on the tube square with its axis.
