Every NC bender reaches accuracy up to ±0.1°, bends up to 185° and stores 16 preset bend angles at 15 MPa working pressure. Speeds vary with pipe size and wall thickness, so confirm the final configuration for your tube with our engineers before ordering.
How It Works
How An NC Semi-Automatic Tube Bender Works
An NC bender keeps the precise, powered bending of a CNC machine but lets the operator handle feeding and rotating — this semi automatic pipe bending machine is a simpler, lower-cost build for small and medium batches. The heavy casting head and hydraulic bend arm of the NC pipe bender still deliver ±0.1° repeatable bends.
- 1
Operator Feeds & Rotates
The operator sets feed length and rotation between bends by hand (electric rotation optional).
- 2
Hydraulic Clamp & Mandrel
Hydraulic clamping and a mandrel shift hold and support the tube so the wall does not collapse.
- 3
Hydraulic Bend On A Casting Head
The rigid casting head bends the set angle under hydraulic power, up to ±0.1° accuracy.
- 4
Repeat To The Program
The NC control repeats the stored angle bend after bend for consistent parts across a batch.
NC vs CNC
NC Or CNC: What Is Different
Both bend the same pipe to the same precision. The difference is how much the operator does and what that means for batch size and budget.
Bending & Accuracy
Both bend hydraulically to ±0.1°. The NC casting head gives the same clean, repeatable bend on the arc.
Best Batch Size
NC suits small and medium batches and mixed parts; CNC pays off on large, repeatable production runs.
Investment
NC is the affordable entry into precision bending; step up to CNC when volume grows.
Selection Guide
How To Choose Your NC Bender
Start from your pipe size and your batch, then let our engineers confirm the model and tooling.
- By Pipe Size
The model number is the max tube OD, from 38NC up to the heavy 219NC — pick the model that covers your largest pipe.
- By Material
Carbon steel capacity is higher than stainless at the same model, so tell us both material and wall thickness.
- By Batch & Budget
Small to medium batches and mixed work suit NC; high-volume repeat parts justify a CNC upgrade.
- By Automation
Add optional electric rotation for faster, more consistent multi-plane bends without going full CNC.

NC Bender FAQ
NC Tube Bender Questions
An NC bender is semi-automatic: hydraulic bending with manual feeding and rotating (electric rotation optional), reaching accuracy up to ±0.1° at a lower investment. A CNC bender is fully automatic with electric feeding and rotating and touch-screen control. NC is ideal for small and medium batches; CNC suits high-volume multi-bend production.
Nine models from Φ38 to Φ219 mm, matching the CNC scale, in mild steel, stainless steel, copper and aluminum. Send your exact pipe diameter, wall thickness and bend radius and we will confirm the right model.
Yes. Every Telhoo NC tube bender is a hydraulic pipe bender: a hydraulic cylinder drives the bend arm on a rigid casting head for powerful, repeatable ±0.1° bends on pipe up to Φ219 mm. Unlike small manual hydraulic pipe benders, these are full industrial semi-automatic machines.
Yes. Electric rotation, extra tooling stacks and non-standard configurations are available. Tell us your parts and output and our engineers will recommend the right setup.
