Feeding & Rotating
NC bending uses manual feed and rotate (electric rotation optional). CNC bending uses fully automatic servo feeding and rotating.

Hydraulic Bending, Casting Head, ±0.1° Accuracy
Nine NC tube bender models from Φ38 to Φ219 mm, each an NC tube bending machine (also called an NC pipe bending machine) and a cost-effective choice for small and medium batch pipe bending in steel, stainless steel, copper and aluminum.
Semi-automatic hydraulic pipe bending machines with manual feeding and rotating (electric rotation optional), plus hydraulic clamping and mandrel shift. The casting machine head holds bending accuracy to ±0.1°. The NC series is the lower-cost route for small and medium batches across the full Φ38 to Φ219 mm scale.









The model number is the maximum tube OD in mm. Carbon steel and stainless capacities differ by wall thickness. Figures are the rated values for each model.

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.

An NC bender bends under power like a CNC machine, but the operator handles 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.
The operator sets feed length and rotation between bends by hand (electric rotation optional).
Hydraulic clamping holds the tube while the mandrel shifts inside it, so the wall does not collapse or wrinkle. Every NC model works as a mandrel bender, and the page on mandrel tube bending explains when a mandrel is needed.
The rigid casting head bends the set angle under hydraulic power, up to ±0.1° accuracy.
The NC control repeats the stored angle bend after bend for consistent parts across a batch.
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.
NC bending uses manual feed and rotate (electric rotation optional). CNC bending uses fully automatic servo feeding and rotating.
Both bend hydraulically to ±0.1°. The NC casting head gives the same repeatable bend.
NC suits small and medium batches and mixed parts. CNC pays off on large, repeatable production runs.
NC is the affordable entry into precision bending. Step up to CNC when volume grows.
Start from your pipe size and your batch, then let our engineers confirm the model and tooling.
The model number is the max tube OD, from 38NC up to the heavy 219NC. Pick the model that covers your largest pipe.
Carbon steel capacity is higher than stainless at the same model, so tell us both material and wall thickness.
Small to medium batches and mixed work suit NC. High-volume repeat parts justify a CNC upgrade.
Add optional electric rotation for faster, more consistent multi-plane bends without going full CNC.
As on every Telhoo bender, die material is matched to your pipe. Tell us what you bend and we supply the matching die set.
45# steel dies as standard, Cr12 optional for longer tooling life on high-volume work.
Aluminum copper alloy mandrel and wiper so there is no galling on the stainless surface.
Nylon or polished dies protect soft copper and aluminum tube for HVAC and decorative work.
Every machine ships with mandrel, wiper die, sensors, spanner and operation manual.

An NC bender is semi-automatic. It uses 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 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 propose a setup.
Stainless work-hardens and needs roughly twice the bending force of mild steel at the same section, so every model in the range carries two ratings. The 38NC takes Φ38.1 × 2.0 mm in mild steel but Φ31.75 × 1.5 mm in stainless. The 168NC takes Φ168 × 14 mm against Φ135 × 10 mm. Always quote the material with the tube size.
It depends on the model, whether you add electric rotation, and the tooling for your tube. An NC bender costs less than the CNC machine of the same size because the operator feeds and rotates by hand. Send your tube size, wall thickness and material and we reply with a model and a price.
Yes. We bend your sample parts and inspect them before shipment, and a factory acceptance test is available on request. Send the sample tube and drawing with your inquiry.
Send your pipe diameter, wall thickness, material and output, and our engineers will confirm the right NC model, tooling and options.
