Tube Cutting

Tube Cutting

  • When cutting tubing, it is important to produce a square end, free of burrs. Tubing may be cut with a tube cutter or hacksaw.
  • The cutter can be used with any soft metal tubing, such as copper, aluminum, or aluminum alloy. Correct use of the tube cutter. Special chipless cutters are available for cutting aluminum 6061-T6, corrosionresistant steel, and titanium tubing.
  • A new piece of tubing should be cut approximately 10 percent longer than the tube to be replaced to provide for minor variations in bending. Place the tube in the cutting tool with the cutting wheel at the point where the cut is to be made. Rotate the cutter around the tubing, applying light pressure to the cutting wheel by intermittently twisting the thumbscrew.
  • Too much pressure on the cutting wheel at one time could deform the tubing or cause excessive burring. After cutting the tubing, carefully remove any burrs from inside and outside the tube.
  •  Use a knife or the burring edge attached to the tube cutter. The deburring operation can be accomplished by the use of a deburring tool. This tool is capable of removing both the inside and outside burrs by just turning the tool end for end.
  • When performing the deburring operation, use extreme care that the wall thickness of the end of the tubing is not reduced or fractured. Very slight damage of this type can lead to fractured flares or defective flares, which do not seal properly.
