Technology & Features

ENGINEERED FOR EVERY BEND

Advanced rotary draw bending technology. Built around precision, control and repeatability. Powerful bending systems, interchangeable tooling and intelligent CNC controls work together to produce consistent bends across a wide range of tube, pipe and profile applications.

01

ROTARY DRAW TECHNOLOGY

A rotating bend former draws the tube around a controlled radius, producing accurate bends with consistent geometry. Ideal for cylindrical and formed components requiring repeatable bending angles.

02

INTELLIGENT CNC CONTROL

Programmable bending controls manage bend angles and operating parameters, allowing operators to store settings, repeat components and maintain consistent results across production batches.

03

PRECISION BENDING TOOLING

Matched bend formers, clamping dies and pressure dies securely position the material throughout the bending cycle. Interchangeable tooling accommodates different tube sizes, profiles and centreline radii.

04

NON-MANDREL BENDING

Controlled rotary forming enables suitable tube and pipe sections to be bent without internal mandrel tooling. Correct tooling selection and bend radius help minimise unwanted deformation and maintain component quality.

05

SPRINGBACK CORRECTION

Programmable or adjustable springback compensation accounts for material recovery after bending, helping achieve the required finished angle across different material grades and wall thicknesses.

06

WORKSHOP PRODUCTIVITY

Compact machine arrangements, convenient operator controls and optional material positioning equipment support efficient loading, setup and repeat bending operations.

ROTARY DRAW TUBE BENDERS FAQ & KNOWLEDGE CENTRE

Choosing the right rotary draw tube bending machine depends on your material, tube diameter, wall thickness, required bend radius and production volume.
MACH supplies, installs and supports rotary draw tube and pipe bending machines across the UK & Ireland, helping fabricators select the correct bending capacity, tooling
and control configuration for their applications.

A rotary draw tube bender forms tube or pipe around a rotating bend die to produce a
controlled bend radius and angle.
The material is held by clamping tooling while the rotating former draws it into the required shape. This process is widely used for repeatable bends in tubular frames, handrails, pipework and fabricated components.

The tube is positioned against a bend former and secured using a clamping die. As the former rotates, the tube is drawn around its radius while additional tooling supports and
guides the material.
The finished bend is determined by the tooling radius, bending angle, material properties and machine settings.

Rotary draw bending forms a localised bend around a fixed-radius die, making it suitable for elbows, repeated angles and components with defined bend positions.
Roll bending progressively passes material through rollers to produce larger-radius curves, arcs and rings.
The two processes serve different applications and generally require different
machinery.

Non-mandrel bending forms tube without an internal support tool. It is commonly suited to heavier-wall material and applications where the bend radius permits acceptable forming without excessive flattening. Mandrel bending uses internal support to help control tube deformation, particularly on thinner-wall material and tighter bend radii.

Yes. Suitable machines can bend square, rectangular and other selected profiles using tooling designed for the material’s cross-section. The achievable radius and finished quality depend on profile dimensions, wall thickness, material grade and machine capacity.

Rotary draw bending machines can process mild steel, stainless steel, aluminium, copper and other suitable metals. Each material has different strength and springback characteristics, so bending capacity, tooling and machine settings must be selected accordingly

The minimum achievable bend radius depends on the tube diameter, wall thickness,
material properties, tooling and machine configuration.
Bend radius is commonly specified as the centreline radius (CLR), measured from the centre of rotation to the centreline of the tube. Tighter radii may require additional tooling or mandrel support to control deformation.

Yes. Suitable rotary draw bending machines can produce bends up to 180 degrees.
The maximum achievable angle depends on the selected machine, tooling and component geometry.

Springback is the tendency of a tube to recover slightly towards its original shape after the bending force is removed.
To compensate, the machine may bend beyond the required final angle. Suitable programmable controls can store or adjust this correction to improve repeatability.

Yes. Multiple bends can be produced by repositioning and rotating the tube between
bending operations. Some machines offer programmable angle sequences and optional positioning equipment. More complex automated feeding and rotation are generally associated with multi-axis CNC tube bending systems.

Typical tooling includes a bend former, clamping die and pressure die or counter-former.
The correct tooling depends on the tube’s outside diameter, cross-section and required
centreline radius. Different tube sizes or bend radii may require additional tooling sets.

Start with your maximum tube diameter, wall thickness, material grade, smallest
required bend radius and bending angle. Consider whether you need square or rectangular profile bending, repeat programmable angles, springback compensation or positioning equipment. MACH can review your component drawings and production requirements to help determine the correct machine capacity and tooling.
