Tube laser cutting adds a rotary axis so round, square and rectangular section can be cut, pierced and profiled along its whole length in one operation. It replaces sawing, drilling, notching and marking with a single machine pass, and its real value is not the cut itself but everything downstream that no longer needs a fixture.
What the machine can do to a length of tube
Cut to length square or mitred, pierce holes and slots anywhere on the circumference, profile the ends so two tubes meet without a gap, add tabs and slots so an assembly self locates, and etch part numbers or fold lines. All of that happens from one file with the tube loaded once, so features on opposite faces are in register with each other by construction.
Why it changes the cost of a welded frame
A conventional frame needs a saw, a drill jig, a notching operation and a welding fixture to hold everything in place. A laser cut frame arrives with locating tabs and slots designed into it, so the parts hold themselves in position and the welder tacks rather than clamps. The fixture cost disappears and the assembly error rate falls with it.
Design rules that make it pay
Design the joints as tab and slot so the assembly is self jigging. Keep hole positions dimensioned from a datum on the tube rather than from each other. Allow for the kerf and for the heat affected edge on close fitting joints. And send the model as tubes rather than as a solid, because the machine wants the section and length, not a merged body.
Limits and material
Wall thickness and section size are bounded by the machine, and very heavy wall or very large section moves to plasma or sawing and machining. Highly reflective materials need a suitable source. Long thin sections can bow under their own weight and need support. And the cut edge is a laser edge: clean, slightly hardened and oxidised if cut in air, which matters if it is to be painted or welded.
Questions people ask about laser tube cutting services
What is laser tube cutting?
Laser cutting with a rotary axis that turns the tube under the head, so holes, slots, profiles and end preparations can be cut anywhere on the section in one operation.
Does it replace welding?
No, but it changes it. Self locating tab and slot joints mean the welder positions less and welds more, which removes fixtures and reduces assembly variation.
What sections can be cut?
Round, square, rectangular and many open sections, within the machine's size and wall thickness limits. Very heavy wall goes to other processes.
Do I need to supply a flat pattern?
No. Supply the tube geometry with its features. The machine's software handles the wrap from the three dimensional model.
