Tube processing: 4 operations in 1 CNC machine

Multifunctional tube processing machine. Straightening. End-forming. Tube bending and cutting.

See what’s possible
CNC tube processing

The 4-RUNNER is a multi-operation CNC tube processing machine. Starting from a coil, it straightens, end-forms (using a 6 forming station), faces, rolls, bends, cuts and finally unloads the finished part. All in one system.

You will be spoiled by the choices

The machine can be configured and used with a variety of modules. You can use it for a single function / process or as a complete combined production process (from feeding to unloading cut, bent and end-formed parts). This modular tube processing system can be built according to your needs or added to over time.

Choose your tube processing machine

The equipment is offered in two different versions,
just choose the one more adapted to the tube processing needs and product you wish to produce.


Up to Ø 12.7 mm (0.5’’)

Straightens, end-forms, cuts and bends, with flexion or variable radius method. It can perform multi-radius, right-hand and left-hand in-process tube bending. 

The system is particularly well suited for making flat and 3D serpentines; these parts are typically used in the refrigeration, HVAC, automotive and household appliance industries.


Up to Ø 22.2 mm (0.875’’)

Straightens, end-forms, cuts and bends, with flexion or variable radius method. It can perform right-hand and left-hand in-process bending operations.

The system is particularly well suited for making pipes that carry fluids, typically for the automotive, air conditioning, heating and refrigeration industries.

Tube bending technology
Compression and draw bending

Compression and draw bending

The 4-RUNNER H3 allows you to use flexion and stretching bending technologies to combine bending speed with the possibility of making short stretches between bends and/or between bends and formed ends. For the best flexibility and productivity.

In-process right-handed/left-handed bending

In-process multi-radius right-hand and left-hand bending from coil

The low-profile geometry of the bending head of the 4 RUNNER H1 allows right-hand and left hand in-process and multi-radius operations. It is ideal for making 3D serpentines with more than one bending radius and parts with particular complicated geometries.

Variable radius

Variable radius

Variable-radius bending offers many advantages, primarily more sophisticated bends and faster cycle times.

Heavy or Light end-forming, according to your needs

Light end-forming module

End-forming module with 3 push passes or with 1 push and 1 revolving pass.


Heavy end-forming module

End-forming module with 6 push passes or with 4 push and 1 revolving pass.

Very fast. Very versatile.

Your process in just-in-time perspective
Simplified logistics

No intermediate steps. No separate set ups for subsequent process. No work in process inventory.

Perfect repeatability and quality

The entire production controlled in the background.

Constant production quality

Across all shifts because everything is performed on one machine.

High automation

No expertise needed to run the system.

Anything is feasible

Anything is feasible with this BLM modular CNC tube processing equipment. Exploiting its potential to the highest level is very simple.

"All-electric", all easier
Minimum setup time and constant accuracy

All machine movements are via electric servos. Part bend positions, tooling information, and power parameters are all saved together in the part program. When a job is repeated you simply mount the tools and recall the program. No further mechanical adjustments are needed. This guarantees quick setup and changeover and provides lot to lot repeatability. It also eliminates the need for a bender set up specialist.

Low maintenance and high reliability

All electric operation offers simplified wiring and the elimination of hydraulic components. This reduces the need for routine maintenance and provides more consistent bending. The obvious advantage is that the 4-RUNNERis easier to maintain, safer to use and more reliable.


“All-Electric” technology ensures quiet and clean machines.

Minimum energy consumption, equal to 4 kW

We have reduced electrical energy consumption with no reduction in working capacity.

Guaranteed repeatability

All setup parameters are saved with the part program. No mechanical adjustments mean maximum repeatability of the parts during bending operations. Furthermore, tube forming is measured in real time to guarantee part repeatability without wasted time or efficiency.

From the idea to the part in one click

It takes just a moment to start production: import a file directly from 3D CAD or input the tube geometric data. The VGP3D software automatically creates a ready to run part program.

From the idea to the part in one click
4 operations > 1 single control point

With VGP3D you have one machine program for both bending and forming.
This provides you with a complete production cycle time for estimates and optimal production planning.
Furthermore, you can view all operations in simulation mode to check feasibility and optimize the process.

All this from one single control point.

The software that makes the difference: VGP3D

The VGP3D 3D programming software makes the real difference:
it checks part feasibility, eliminating the risk of collisions which typically occur during the first practical try out
it calculates the real production cycle time in advance, slashing the time needed to create customer quotes or determine feasibility
it automatically generates the machine program.

It can import and recognize CAD files automatically. I can even import tubes with non-round sections. All in one environment, either in the office or on the machine.


Immediate verification of the match between theoretical and practical. Measuring the distance between the tube and the machine component. Measuring the amount of interference with other objects.


Full graphic part optimization. Waste elimination. The operator is able to redraw the part and start the production without assistance of a set up person.


Export directly from VGP. Faster (1 min. vs. 3.5 min.) than from CAD. Export full 3D tube assemblies.
