BLM Group adds to tube bending machine range with 4-Runner H1 for tube up to 12.7 mm

​BLM Group’s 4-Runner family is expanded with the arrival of the 4-Runner H1, a system dedicated to complex processing on tubes of diameter up to 12.7 mm – the existing 4-Runner H3 processes tubes up to 22 mm in diameter.

The 4-Runner H1 is a all-electric, multi-radius and variable radius coil-fed bending system that is capable of flexion, right-hand and left-hand in-process bending and can easily be integrated with a Smart system for complete and automatic bending with mandrel from a coil.

It is particularly suitable for making tricky parts, such as flat or 3D serpentines and small tubes, and in general for all parts that are “simply impossible for everyone else”.

The 4-Runner H1 has six controlled electric axes. All clamping and bending axes are electric, which means equipment calibration can be automated and made extremely simple.

The torque control on the clamp ensures safe and repeatable gripping. Once identified, the correct calibration parameters can be saved and retrieved for future use on the same tools, with important advantages in terms of tooling time.

For feeding from coil, the 4-Runner H1 is equipped with a new coiler provided with a motor controlled in both directions and a clutch for idle operation; controls are inserted directly by the part program.

Orbital cutting, both internal (4RIPC) and external (4RC) on 4-Runner H1 are entirely electric. Two brushless motors control the rotation and the movement of the cutting wheel, guaranteeing process accuracy and repeatability with no need for manual adjustments.

The 4-Runner H1 also boasts the VGP3D programming software package. Three-dimensional graphics show the part as the coordinates are entered, allowing a simple and immediate check of programming correctness. This is followed by simulation to verify the entire working cycle, including checking for potential collisions.
