TUBE SAW TOOLING

As a part of Tube Form Solutions full service tube fabrication capabilities we design and manufacture a wide variety of tube saw cutting tooling, including the following:

Tube Saw Cutting

Saw cutting provides square cut within 1 mm profile tolerance. The disadvantage of tube saw cutting tooling is that it produces shavings or chips resulting in material loss from the tubing being cut. Tube fabricators usually need to wash or remove this debris from the finished tube and from the cutting area.

Blade shearing - (E.g. Machine model TC80 or TT)

The advantage of blade shearing is speed of the cut. The machine cycle time is only 4-5 seconds. The end profile tolerance is 1.5 -3mm depending on the wall thickness of tubing. The disadvantage is the thinner tubes will be more out of round due to blade deformation and the material slug from the blade cutting is lost material.

The advantages of dual blade shearing tube saw cutting is speed and a high quality 1-1.5 mm end profile. The speed of dual blade shearing is faster than saw cutting with an average cycle time 4-6 seconds. The disdvantage is that the dual blade shearing tooling is more costly and requires two perishable blades that need to periodically be replaced. This tooling also results in two material slugs being wasted after each cut, one from each blade.

Rotary shear tooling (E.g. Brehm or Tru-motion)

Rotary shear tooling is positioned both inside and outside of the tubing to support the material being cut The tools are then oscillated to fracture the outside wall of the tubing.

The advantage is a fast cut in 1.5 to 3 seconds with no material loss to shavings or slugs. The disadvantage is that rotary shear tooling can only used in straight line tube cutting due to the presence of a mandrel inside the tubing being cut.

Rotary facing or chamfer tooling. (Spin cut)

Tooling squares face or chamfer the end of the round tube to prepare the cut end for the next forming process. Rotary facing typically removes the potential of tube splitting from subsequent end forming processes.
