Allroad: tubes like you've never imagined

You are not limited to just round, square or rectangular. Special shaped tubes or open sections can be programmed and cut without problems.

The use of non-standard shaped tubes (i.e. not round, square or rectangular) has expanded greatly over the years. You can process special sections and even open shapes without any special equipment. Thetube loading and handling capabilities combined with the design freedoms of the BLMelements software suite peerless provide unmatched capabilities.

Safe, automatic production change over- no waste of time

The machine manages changeovers (on standard or special shaped tubes) automatically: loading, handling and unloading are automatically adjusted from one job to the next according to changes of bar shape and size. This automatic adjustment prevents the risk of collitions or production interruptions that can occur from oversights or incorrect adjustments caused by inexperience.

Automatic loading: adjust from 12 to 152 mm (.5” – 6.0”) n zero seconds

The bundle loader of LT22D / LT FIBER machines does not require any manual adjustments to switch from one tube shape to another.

This makes the entire changeover process more convenient: there is no downtime during a change of production. You can use this productivity advantage to reduce your part cost.

The right grip for every tube

A secure grip is essential for proper tube handling.

With the anti-crush feature of LT722D and LT FIBER you can handle tubes of any weight, without deforming the thinnest walls.

Depending on the requirements the chuck manages both the closing force and position of the jaws so that grip is always suited to the high dynamic loads of the machine.

Finished parts are already sorted

Programmable unloading to various position means you do not need to manually separate parts from different batches or different orders. You can remove finished parts from one side of the machine while production continues on the other. Easily segregate prototypes from the main production.

Cutting with LT722D / LT FIBER: no experience needed

The correct set up parameters, i.e. determining the best laser settings for the material type and thickness, is integrated in the machine control. There is a complete database of cutting parameters for all materials and thicknesses which provides the ability to adapt the laser parameters for the instantaneous speed conditions and cutting path.

Part quality, inside and out

An internal suction probe or ‘spoon’ can be inserted into the I.D. of round tubes to keep the inner surface of the tube clean when cutting. The ‘spoon’, which automatically adjusts to the tube diameter, catches dross and cutting debris and vacuums out particles that can adhere to the inside of the tube to produce a clean dross free internal finish.

Dynamic nesting: saving of time and material

Do you need to optimize material utilization? The machine will do this automatically setting the sequence of parts to be cut to minimise end of bar scrap. A valuable function which becomes even more convenient when combined with the ability of unloading parts to different locations. This provides a considerable time savings and makes it easier to collect parts that are discharged in a tidy fashion.

Artube: from the drawing to the part in one click

Drawing a part or an entire frame and transforming it into a machine program takes only a few seconds. You can import 3D models of parts drawn in other CAD programs and send everything needed to start production to the machine on the fly. With Artube you can exploit all the Lasertube’s potential from the word go, without errors.

Protube: error-free planning

Create part programs and easily organise them into production batches. With Protube you can automatically calculate the number of bars needed, optimize the nest to create the minimum scrap, estimate the hours needed and monitor production progress in real time.

Active Tools

Active Tools: make tube processing even simpler and more robust

Active Marking

Do you need the ability to identify and track every single part produced? Parts can be dynamically marked with Active Marking. Assign the area of the part to mark, then enter the text or data. The Lasertube machine will automatically add the updated value in real time: time, date, sequential part number / ID or even the order number. Handy and easy!

Active Piercing

You will experience a considerable increase of productivity on thick walled tubes when using the optimised Active Piercing function. Increase piercing speed and reliability even when faced with inconsistent material quality and thickness. Spectacular! This is the definitive tool for compensating for the errors that are created by irregularly shaped or bowed tubes. Active Scan can prevent positioning errors of the cut features when the tube is misshaped or not sufficiently rigid to be effectively constained by the mechanical supporting and guiding devices. Active Scan is an optical device that works in the background to calculate the compensations needed to adjust the part program to ensure that the required tolerances are achieved. Accurate!

Active Speed

Optimal cutting quality from the first part! You can obtain high cut quality on all parts even if you do not have specific laser cutting expertise. With Active Speed, the Lasertube machine will dynamically manage all the cutting parameters and deliver the same cut quality in difficult cutting conditions that you expect in common laser cutting jobs. Safe!

Technology within everyone’s grasp

A guided graphical interface is presented on a large touchscreen monitor.

The programming requires just a few simple operations because most of the options are already automatically extracted from the part program.

The ability to edit ensures the highest possible flexibility and adaptability.

All-In-One: bending and laser - made for each other

Bending and laser cutting this turns a tube into a finished product. But the use of two separate technologies has always caused difficulties. BLM GROUP machines are created to seemless marry these two technologies solving the problems of locating holes on bent tubular products. All automatically.
