Nevatronix Laser cuts round tube — the profile behind railings, hoops, and round welded frames — from 12 to 220 mm outside diameter on a five-axis fiber tube cell. What sets round tube apart is the rotary axis: it turns the tube under the beam so features wrap around the full circumference, which is exactly what a clean tube-to-tube joint needs.

Why round tube is different
On flat sheet or square section, features sit on flat faces. On round tube, every feature is somewhere on a curved surface, and its true shape depends on the angle it meets that surface. Drill a hole straight through a round tube and the exit is an ellipse, not a circle; cope one round tube onto another and the joint is a saddle whose profile changes continuously around the contact line. The rotary axis is what makes these tractable — it presents each feature to the beam at the right angle, so the laser cuts the true developed shape rather than an approximation.
That capability turns three traditionally separate operations into one:
- Saddle (fishmouth) copes for tube-to-tube joints, cut to the exact intersection profile including compound angles.
- Holes and slots at any wrap position, including through-holes whose true elliptical outline is calculated by the program.
- Angled and mitered ends for frames and bent-to-fit assemblies.
Applications by industry
Round tube is the profile of choice where the look is clean or the load is distributed. In architectural work it is handrail and railing with weld-ready joints. In gaming and smart automation it is round framing and guarding inside cabinets and equipment. In material handling and transportation it is frames, hoops, and structural members where repeatable fit-up matters across a run. Most of these parts move on to welding, and because the copes and bevels are cut in, they clamp and run with no pre-weld prep beyond cleaning.
Design tips for round tube parts
- Let the program develop the true shape. Model the intended joint; the cell calculates the elliptical holes and saddle profiles from the geometry.
- Keep wall within 12 mm. That is the cell ceiling across materials.
- Tolerance the connections. Call out the holes and copes that must register against mating parts; we hold ±0.1 mm where it counts.
- Give us the assembly, not just the part. For a welded frame, the full model lets us cut tab-and-slot or saddle features that self-locate at weld-up.
When another profile or process fits better
- Flat-faced frames. For cabinet skeletons and rectangular frames, square and rectangular tube is the better profile.
- Plain cut-to-length. With zero or one feature, a saw is faster and cheaper.
- Beyond the envelope. Round tube over 220 mm OD or wall over 12 mm is outside the cell — we coordinate a partner facility.

Quoting a round tube part
Send a STEP file of the tube or the full weldment with diameter, wall, material, and quantity to our quote page. We confirm the cut sits within the 220 mm envelope and quote from a five-day prototype through production out of our ISO 9001:2015 shop in Las Vegas.
