The LT-FREE five-axis laser cutting system is ideal for three-dimensional parts, bent, hydroformed or pre-assembled tubes or flat and pressed sheets.
Traditional cutting, drilling, piercing, milling and deburring operations, which are normally carried out in sequence, can now be performed on a single machine in a single cycle.
This makes finished parts without 'work in progress' inventory, consequently reducing material handling costs and streamlining the entire production process - as well as downsizing the space needed for storage.
The system is equipped with a fibre laser capable of processing any type of metallic components (mild steel, copper, aluminum, brass, stainless steel, galvanized steel, etc.) at high speed with excellent quality.
- trimming and piercing on bends
- high quality and accurate cuts, ideal for welding by robots during a later assembly stage
- finishing of hydroformed parts
- piercing anywhere on bent tubes
- preformed sheet trimming
- processing of preassembled frames
For non-stop production 24/7
There are very many LT-FREE automation solutions.
From feeding from box to feeding from the upstream machine.
Tubes can be taken from a jumbled stack of parts in a box or directly from the tube bending machine.
The robot can autonomously manage tube gripping using the viewing system and load the tubes onto the LT-FREE in the correct position.
Previously processed parts can be stored in tidy manner in a specific box.
All loading and unloading operations are performed in the background in this way.
Productivity increases. Quality is constant. Flow is non-stop 24 hours a day, seven days a week.
Dual robot station
The dual robot station configuration allows independent loading and unloading without interrupting the laser cutting process hence boosting productivity.
Handling of parts to be machined
The part is not moved during the cutting operation.
In this way, top-notch accuracy is guaranteed by a five-axis system and the flexibility of a robot handling system.
No special dedicated locating templates are needed for positioning bent tubes.
All machine and handling robot cycles can be programmed directly offline using BLM GROUP programming and simulating software.
Just select material and thickness: the machine will automatically determine all the cutting parameters and set the optimal focus position.
The best way to do what you do everyday
- Reduced process steps
- Shorter cycle times
- Lower capital investment
- Higher productivity
The LT-FREE can make cuts very close to each other. This provides remarkable advantages for separating multiples. Multiple parts can be made on the bending machine and then separated by laser cutting.
Up to 25% material can be saved.
Using laser technology prevents part deformation, improves processing quality and guarantees accuracy and repeatability. It is ideal for preparing parts for assembly by robots at a later stage.
The benefit is even more obvious when processing thin walled tubes.
The advantages of the fiber laser
in addition to mild steel, stainless steel and aluminium alloys, fiber laser can also cut copper and brass
the higher cutting speeds offered by the fiber laser enhances the production capacity of the machine
higher wall plug efficiency lowers power consumption and hence considerably reduces the installed power requirement
- maintenance free
The best way to do what you do every day
The two independent work areas of LT-FREE allow loading / unloading operation without interrupting the cutting process, thus ensuring higher productivity. With thecapability of processing same or different parts on the two stations, LT-FREE also offers maximum production flexibility. And we are talking about real productive flexibility, in the sense that the system is designed to be easily and quickly configured without the need for dedicated jigs for every part to be cut.
Working with LT-FREE allows you to produce a finished component, without the intermediate steps of semi-finished products. The result is material handling cost-reduction, simplified production process and also space saving, as well as the reduction of the space required for storing.
Traditional process steps like cutting, drilling, punching, milling, deburring etc., that are normally executed sequentially, are replaced by one single operation carried out by onesingle system in one single cycle.
The efficiency and enormous flexibility of the process greatly enhances the freedom of the designers in developing new products (both in terms of repeatability and aesthetics) and reduces the "time to market", not only on the tube but also on 3D sheet metal components.
