CNC tube bending and radius rolling are driven directly from your CAD file, which keeps setup time down and makes results repeatable across reorders. Send a model in Parasolid, STEP or IGES and we generate the bend and roll instructions from it.

Tight-radius bends, large sweeping rolls and multi-plane clocked geometries all run on the same workflow. The one thing that decides whether a part can be built as drawn is the centerline radius — model to the CLR values we actually tool for, published in full on our chart, and the part comes off the machine matching the model.

Bending runs on a SOCO SB-63X4A-3S-V CNC tube bender in steel, stainless and aluminum. We keep dies for 0.50, 1.00, 1.25, 1.50, 1.75 and 2.00 in outside diameter, each with a standard centerline radius and, on most sizes, a non-standard one. There is no extra charge for a non-standard die; the standard radius simply gives the most accurate and repeatable bend, so use it wherever the design allows. Your modeled CLR has to land within 0.05 in of a listed radius, and a diameter not on the chart has no in-house die, so ask before you design to it.

Tube is cut on our own tube lasers first, so bent parts arrive at the bender with copes, holes and part numbers already in them. Jobs are quoted by bends, bent tubes and setups plus material by the foot, from 20 ft sticks of stock; setups are charged once per unique part per run, so the per-piece price falls as quantity rises. Send every part of one material in a single multibody file so they share stock.

From Fontana we bend tube for fabricators and OEMs across San Bernardino and Riverside counties, Los Angeles and Orange County, and ship across Southern California. ITAR or export-controlled files should not go through the instant quote; email them to sales@calwestmfg.com.

Common questions

What bend radius should I design to?

Model to the exact centerline radius (CLR) we tool for. Our published CLR chart lists the standard and non-standard radii available for each tube size. Designing to a radius we do not have means the part cannot be bent as drawn.

How much straight tube do you need between bends?

Leave at least 4 inches between bends or rolls, and a minimum of 3 inches of straight tube before and after a bend. Closer spacing risks the clamp die marking the tube or disturbing the previous bend.

Can I put holes or features in a bend?

No. Holes, keys and markings inside a bend cause the tube to deform or crack. Keep features at least 0.75 inch away from the tangent point of the bend.

What tube sizes can you bend?

We keep dies for 0.50, 1.00, 1.25, 1.50, 1.75 and 2.00 inch outside diameter in steel, stainless and aluminum, each with a standard centerline radius and, on most sizes, a non-standard one. The full list is on our CLR chart. A diameter not on the chart has no in-house die, so ask before you design to it.

Is there a charge for a non-standard bend radius?

No. Standard and non-standard dies cost the same. The standard radius gives the most accurate and repeatable bend, so use it wherever the design allows and the non-standard one only when you genuinely need that radius.

Where is the tube bender and who do you serve?

Fontana, California, in the Inland Empire. We bend tube for customers across San Bernardino and Riverside counties, Los Angeles and Orange County, and ship across Southern California.
