CNC Automatic Pipe Bending Machine

Pipe Bending Machine 89CNC

CNC pipe bending machine for tube up to Φ88.9 × 3 mm on a 3800 mm mandrel. Bending is electric as standard with hydraulic available, so the same model covers both quiet in-plant work and heavier duty cycles. Feed 20–700 mm/s, all axes repeatable to ±0.1.

Overview

Product Details

Overview

The 89CNC pipe bending machine is a CNC pipe bender taking tube up to Φ88.9 × 3 mm on a 3800 mm mandrel, 300 mm maximum bend radius, 3.4 tonne frame. Electric servo bending with hydraulic clamping and a hydraulic moving mandrel.

Φ88.9 mm is three-and-a-half inch nominal pipe, which puts this model into pipe spool and structural work rather than furniture. Stainless at this diameter is the hardest combination to bend cleanly — it work-hardens and it buckles — so the mandrel position and the wiper dies matter more than the machine rating does.

FAQ

Pipe Bending Machine 89CNC — Common Questions

Carbon steel tube up to Φ88.9 × 3 mm, with a maximum bend radius of 300 mm and 3800 mm mandrel length, on a 3.4 tonne frame.

Diameter and radius have to be considered together. At Φ88.9 mm a centre-line radius of around 1.5 times the diameter is demanding but achievable with a multi-link mandrel and a wiper die; tighter than that on thin wall risks wrinkling regardless of machine capability.

With the right tooling, yes. Thin-wall stainless is the hardest combination — it work-hardens and it buckles — so it needs a properly fitted wiper die, correct pressure die force and a mandrel positioned accurately relative to the tangent point. Send a sample drawing and we advise on the tooling.

Through a touch screen with a PLC controller, in English or another language on request. Bend sequences are stored and recalled by part number, and an industrial PC option is available where parts are transferred from a CAD system.

Automatic lubrication handles the routine points. Beyond that it is hydraulic oil condition, filter changes and periodic checks on tooling wear and clamp pressure. Worn clamp dies are the most common cause of drifting accuracy on a machine that was previously repeating well.
