Flexible manufacturing systems for tubes and sections
LC5
LC5 is the ideal solution for laser cutting both sheet and tubes in all situations in which installing two separate systems is hardly justifiable due to reasons of dimensions, production volumes or more simply cost-effectiveness.

A single laser source and a single cutting head is capable of switching from sheet to tube processing (and vice versa) immediately, automatically and without needing re-tooling.

LC5 can process metal sheet up to 3000x1500 (or 4000x2000) and round, square, rectangular, oval shaped tubes up to an inscribed diameter of 120 mm and a bar weight of up to 13.5 kg/m.

LC5 can be equipped with either a CO2 laser source with a power of up to 4.5 kW or a fiber laser source with power up to 3 kW. The fiber source is advantageous for cutting high reflecting materials (brass, copper) and for more effective aluminium processing.The cutting process is controlled by sensors which monitor all the main parameters on both the CO2 source and fiber versions. The optimal cutting parameters are selected in fully automatic manner according to the material and thickness. Focus is regulated by a servo mechanism fitted inside the cutting head.

ADVANTAGES:
• tube sheet immediate switch
• automatic tube bundle loader
• automatic unloading
• scrap separation
• BLM GROUP 3D graphic CAD/CAM: Artube
• tidy collection solutions

Flexible manufacturing systems for tubes and sections
LT FIBER
LT FIBER is the new system of the Lasertube family specifically designed and developed for cutting tubes of any section, with the fiber laser source.

The new technology of the fiber laser offers significant advantages in terms of a wider range of materials that can be processed - among them also high-reflective materials such as copper and brass; aluminium (6060, 1050, …) and galvanized iron become also easy to cut. A considerable productivity increase is obtained on small thicknesses of stainless steel.

With a capacity up to Ø 152 mm and a raw tube available in two lengths: 6500 mm or 8500 mm, the LT FIBER laser cutting system is characterized by the following peculiarities:
fully automatic and programmable set-up
fully automatic changeover in just 3 minutes
optimized fiber laser technological database
easy and quick programming through Artube CAD/CAM also for not-experienced operators
bar management in automatic cycle from bundle, singularization, measure, cutting to orderly unloading.
final scrap reduction
The programming software Artube is a three-dimensional, parametric, Artube CAD-CAM package specifically designed, developed and dedicated for tube applications, that amplifies the productivity potential of the machine.

Tube bending machines
4-RUNNER
4-RUNNER is a complete production process starting from a coil: straightening, end-forming (up to six passes), facing, rolling, bending, cutting and controlled unloading of the finished part all in one.
The unquestionable advantage of this combined machining centre is that it can be configured and used with various modules for specific jobs or complete processes from straightening to unloading the finished parts entirely cut, bent and formed.
On bending side, the 4-RUNNER allows to make fixed and variable radius arrangements on the plane and in space, which can be integrated according to design development in automatic sequences without bending problems: all-in-one process, without reworks.
The possibility of combining multiple radius bending or stretching technologies on the same part guarantees the best flexibility and the highest production rates.
On end-forming side, the machine may be configured with four or six push passes or four push and one revolving pass.
Different cutting devices are used according to applications: inner orbital cutter, outer orbital cutter, disc cutter.
Extreme versatility like this means:
• top flexibility for jobs and applications
• top efficiency and low investments costs with integrated processes and the possibility of implementing just-in-time methods
• 3D visual graphic programming (VGP3D) makes using the machine extremely easy, comfortable and safe.
The 4-RUNNER bending centre is particularly suited to machining small and medium size tubes even of very complex shapes typically used in automotive, air conditioning, heating or cooling system applications.

E-TURN
Fully electric bending machine, with right and left bending in process and 3D graphic visual programming (VGP3D)

Some features of E-TURN fully electric machine:
• No mechanical adjustment is needed
• In-process right and left bending, with fixed and variable radius
• Reduced time for programming and change-over
• Enhanced controllability and repeatability
• Increased productivity (by even 20% compared to hydro-electric machines)
• Widest flexibility, thanks to the reduced dimension of the bending head and of the free bending and variable radius positioning
• Increased feasibility of more complex structures
• Tool holders designed for the fully interchangeability with existing BLM machines
• Integrated machine load and load

The machine is programmed by the programming and 3D simulation software BLM VGP3D which allows:
• component feasibility can be checked without physically testing on the machine or making prototype tooling
• pre-production calculation of the real cycle time is known, so production costs and component pricing can be more precise
• by simply inputting the components bend coordinates, the complete bending program is graphically simulated

Machine available in three versions:
ET32 - maximum tube O.D. capacity from 6 to 32x2mm
ET35 - maximum tube O.D. capacity from 6 to 35x2mm
ET40 - maximum tube O.D. capacity from 6 to 40x2mm
ET52 - maximum tube O.D. capacity from 6 to 52x2mm
