Model Comparison
Compare All Nine CNC Pipe Bender Models
Every automatic pipe bending machine in this range shares the same servo-driven control platform; the model number is the maximum tube OD in mm. Smaller models bend faster, larger models bend heavier wall. All figures below come from Telhoo factory data sheets.

How A CNC Bender Runs
Y, B, C: Three Letters Bend The Whole Part
A bend program on the touch screen is just a list of Y, B, C values. Each letter is one electric servo axis of the machine, and the operator only loads the tube.
- Y
Feed The Tube
Electric pipe feeding along the bed, precision ±0.1 mm.
- B
Rotate Between Bends
Electric rotating sets the plane of the next bend, precision ±0.1°.
- C
Bend The Angle
Electric bending up to 190° per bend, precision ±0.1°.
- 1
Hydraulic Clamping
Clamp and pressure die hold the tube with hydraulic force.
- 2
Hydraulic Moving Mandrel
The mandrel supports the tube wall from inside and retracts hydraulically, matched to each model and tube length.
- 3
Touch Screen PLC
Y, B, C or X, Y, Z input in English or any other language. Industrial PC with 3D simulation and CAD import optional.

Dies And Tooling
Your Pipe Material Decides The Die Set
A bender is only as good as its tooling, so Telhoo matches die material to pipe material. Tell us what you bend and the die set comes matched.
02
You bend
Stainless steel pipe
Telhoo fits
Aluminum copper alloy mandrel and wiper, so there is no galling on the stainless surface.
03
You bend
Aluminum pipe
Telhoo fits
Nylon bend, clamp and pressure dies protect the soft aluminum surface.
Every machine ships with sealing ring, sensors, spanner and operation manual.

CNC Bender FAQ
CNC Pipe Bending Machine FAQ
Common questions buyers ask before choosing a CNC pipe bender model and configuration.
The model number is the maximum tube outside diameter in mm: the 38CNC bends up to Φ38.1 × 2 mm, the 75CNC up to Φ76.2 × 3 mm and the 219CNC up to Φ219 × 20 mm thick-wall pipe. Compare all nine models in the table above, then send your pipe data for confirmation.
Every model includes touch screen PLC control, ±0.1° bending precision, ±0.1 mm feeding precision, 190° maximum bend angle, working light, automatic lubrication and CE, ISO9001, UL and EAC marking. The control stores 2000 part files and programs 32 bends per pipe on PLC, or 99 on CNC control.
Yes. Options include robot loading and unloading, punching, cutting, rolling and pushing, double to multi radius stacks, left and right two-direction bending, industrial PC with 3D simulation and CAD import, cooling systems and safety devices.
Standard dies are 45# steel, with Cr12 optional for longer life. Stainless steel pipe runs on aluminum copper alloy mandrel and wiper, while aluminum pipe uses nylon bend, clamp and pressure dies to protect the surface.
Telhoo is a CNC pipe bending machine manufacturer and supplier, building every tube bending machine in our own Zhangjiagang factory since 1991 — with in-house R&D, machining, tooling and testing. You buy the machine direct from the factory, not through a middleman, with full CE and ISO9001 documents.
