Selecting the optimal JUTEC bending machine for fabrication

The selection of JUTEC bending machinery starts with an engineering assessment of tube geometry: outer diameter, wall thickness, material yield strength, and the target centerline bend radius.

For thicker walls and relative bend ratios exceeding 2.5D, non-mandrel machines such as Biegesystem 3000, 6000, or 10000 offer high throughput, rapid tool setup, and compact footprint.

When bending thin-walled stainless steel, titanium, or copper tubing to tight radii (1.5D to 2D), mandrel systems such as Biegesystem 4800, 5000, or 7000 are essential to eliminate wrinkling and collapse.

Mandrel vs non-mandrel bending: technology and boundaries

Non-mandrel rotary draw bending clamps the tube between a rotary former and a slide counter-shoe. The inner tube bore remains free, expediting loading and unloading cycles during workshop jobs.

When bending thin-walled tubing, tensile stresses thin the outer wall while compressive forces cause wrinkling on the inner radius. Mandrel bending overcomes this by inserting an internal stabilizing mandrel.

JUTEC internal mandrels support the tube inner diameter directly at the point of plastic flow, while external wiper dies prevent wave formation, delivering precise cross-sections for high-pressure systems.

Bending radius calculation and cross-section integrity

The primary engineering metric is the relative bending ratio R/D, where R represents the centerline radius and D indicates tube outer diameter. Tighter ratios demand higher machine rigidity and clamping force.

JUTEC machines feature continuous hydraulic and mechanical pressure adjustment on the counter-shoe and clamping die. This compensates for metal yield variance and prevents tube cross-section flattening.

For demanding stainless steels such as 304, 316Ti, and heat-resistant alloys, articulated ball mandrels are selected with pitch dimensions matched to the bend angle, keeping ovality within DIN norms.

Material springback compensation and digital parameters database

After the bending torque is released, metallic profiles exhibit elastic springback. The extent of angle recovery depends on the elastic modulus, yield tensile limit, bend radius, and tube heat treatment.

JUTEC 5000, 7000, and advanced 6000 series benders integrate automatic springback compensation algorithms, allowing operators to program bend angles with 0.1-degree incremental resolution.

The CNC unit stores up to 200 material parameter sets. In monitored bending mode, real-time comparisons between command and feedback angles automatically correct the final stroke displacement.

Tooling alloys for stainless steel, copper, and thin-walled pipes

External surface quality is paramount in sanitary, food, pharmaceutical, and aerospace piping. Surface scoring, galling, micro-cracks, and tooling contact abrasions must be completely avoided.

For stainless steel and titanium alloys, JUTEC manufactures slide counter-shoes and wiper dies from specialized high-hardness aluminum bronze. Bronze contact elements prevent material pickup and galling.

All JUTEC bending formers feature precision CNC-ground tube grooves. The polished former contact surfaces cradle the tube profile uniformly, distributing clamping loads during the rotation sweep.

CNC automation and programming of complex spatial tube spools

Modern fabrication of industrial manifolds requires executing consecutive bends across a continuous tube length with varying angles, radii, and spatial rotation planes in three dimensions.

The JUTEC control terminal incorporates an intuitive 10-inch color touch display. Operators can program sequences comprising up to 50 progressive bending steps per pipe workpiece.

The onboard controller calculates developed tube cutoff lengths, accounting for material elongation at every bend arc. Program transfer and database backups proceed via USB or local network connection.

Linear positioning carriages and tube spatial rotation control

In structural frame, boiler, and hydraulic manifold manufacturing, maintaining exact distances between adjacent bends and precise plane-of-bend rotation is critical for assembly alignment.

JUTEC 5000 and 7000/9000 mandrel installations are equipped with longitudinal guide beds featuring adjustable length stops or high-precision servo-driven feeding carriages.

The carriage rotating collet chuck positions the tube along its axial rotational degree of freedom with pneumatic disc locking. This delivers repeatable precision without manual alignment templates.
