Four Bending Machines, One Control Platform

Pick the machine by tube size and lot size. All four run the same touchscreen control, so one operator moves between them without retraining.

Section roll bending machine curving a steel tube into a wide arc

Roll Bending Machine

Three-roll section bender for handrails, canopies, tanks and coils where the radius is measured in meters, not millimeters. Hardened rolls for tube, pipe, angle and flat bar on the same frame.

  • Tube to Ø219 mm
  • Radius from 300 mm to open arcs
  • Profile rolls included
  • Digital roll position readout

Tube end forming machine flaring the end of a stainless tube

Tube End Forming Machine

Ram and rotary end formers that expand, reduce, flare and bead tube ends in one clamping. Pairs with the benders so exhaust tips, connector ends and hose barbs leave your line finished.

  • Ø6-127 mm capacity
  • Up to 6 forming stations
  • Cycle time from 4 s
  • Servo or hydraulic ram

Built Around Repeatability, Not Speed Claims

A bender earns its keep on part number 4,000, not on the demo bend. These are the details that keep angle and plane accurate after two years of three-shift work.

  • Springback compensation per lotThe control measures and corrects for each batch of tube, because no two steel lots bend the same.
  • Hardened, ground toolingBend dies, clamps and wiper dies machined in-house to 52 HRC and matched to your tube spec before shipping.
  • Direct-drive servo axesNo belt stretch between motor and bend arm. Positioning verified with a laser tracker at FAT.
  • Collision-checked programsBend sequence simulated on the control before the first tube is clamped, so prototypes survive attempt one.

A Factory That Bends Its Own Test Parts

ARCBEND machines 22,000 m² in Suzhou with tooling manufacture, machine assembly and a bend trial bay under one roof. Before crating, every bender runs your drawings: we film the cycle, measure the parts on a CMM arm and mail you the bent tubes with the report.

  • 22,000 m²assembly and tooling plant
  • 420+machines shipped last year
  • 100%machines bend-tested before crating
  • 72 hspare parts dispatch, CN and EU stock

From Tube Drawing to Accepted Part

One application engineer owns your order through five gates. You see parts and data before the machine leaves.

  1. 1

    Part review

    Send tube drawings, material and monthly volume. Machine and tooling proposal back within 24 hours.

  2. 2

    Bend trial

    We bend your parts on the quoted configuration, film it and courier the tubes to your QC.

  3. 3

    Build & FAT

    Machine assembled, laser-tracker checked and run on your parts again while you watch live.

  4. 4

    Ship & install

    Vacuum-foil crating, then our engineer levels, commissions and trains your operators on site.

  5. 5

    Tooling & support

    New bend dies from your drawings in 3 weeks, remote diagnostics on the control for life.

Questions Fabricators Ask First

Not covered here? Put it in the form and an application engineer answers within one working day.

What tube sizes and materials can your machines bend?

The range covers Ø6 to 219 mm in carbon steel, stainless, aluminum, copper and titanium. Thin-wall stainless down to 0.8 mm bends with mandrel and wiper die support; heavy schedule pipe up to 14 mm wall runs on the hydraulic NC machines. Send your tube spec and we confirm the exact machine and tooling set.

Can you bend square and rectangular tube?

Yes. Square, rectangular and oval sections run on the CNC benders with profiled dies that support the flats through the bend, and on the roll benders for large arcs. Fitness and furniture customers bend 50×70 oval and 40×40 square daily without section collapse.

How do you prevent wrinkles on thin-wall tight-radius bends?

Wrinkling is controlled by the mandrel and wiper die, not by slowing the machine down. We match mandrel ball count and wiper rake to your wall factor and centerline radius, then prove it during the bend trial. At 0.8D CLR on 1 mm stainless the inside of the bend stays smooth enough for polished handrail work.

Do you run bending trials before we order?

Always, and you should insist on it from any supplier. Send drawings or a sample part, we bend it on the quoted machine, film the full cycle and courier the parts to you with a dimensional report. The trial is free for standard tube specs.

What tooling comes with the machine, and how fast are changeovers?

Each machine ships with tooling for the parts quoted: bend die, clamp, pressure die, wiper and mandrel, machined in-house and test-fitted at FAT. Extra sets from your drawings take about 3 weeks. Quick-lock tooling swaps in roughly 15 minutes, and the program library recalls all axis positions per part number.
