High speed laser cutting of large sheets
Latest laser cutting and profiling system that can handle material up to 4m x 2m offers increased cutting and positioning speeds during profiling coupled with high precision.
For some considerable time now, an ever increasing number of customers swear by the extreme speed and precision of Byspeed laser cutting machines The only failing: The limitation to sheets up to 3 x 1.5m

Mid range press brakes, bending cells shown
As well as introducing mid-range pressbrakes, a Swiss manufacturer demonstrated its progress in operator-independent robotic bending cells using various press brakes at EuroBLECH.
This is now a thing of the past, since Byspeed can also available handle large format sheets.
The Byspeed 4020, which was first presented at Euroblech 2004, now also permits material up 4m x 2m to be processed.
Bystronic has thus closed a gap in the existing portfolio.

Integration of process produces best laser cutting
If laser cutting process time is to be minimized and simultaneously, the quality of the cutting result is to be maximized, perfect integration of all process elements is required, reports Bystronic.

"Following the decisive success of Byspeed in recent years, and the subsequent demand for large format laser cutting systems, the expansion was a logical and necessary step." is how Christoph Schuepbach, Head of the Bystronic Market Region Europe North/East explained the development.
The new Byspeed 4020 is extremely compact but at the same time demonstrates the same excellent qualities of its 'baby' sister, the Byspeed 3015.
In a word, these are the unique positioning speed coupled with the high precision and process reliability for all customer parts, regardless of the contours.
In fulfilling this extensive demand, Bystronic has laid to rest a widespread conception that high speed cutting is limited to straight edges.
This, however, places the highest demands on the laser cutting machine, since every facet of the complete system must be designed for high speed.
This starts with the laser source, and hence Byspeed offers laser powers of between 4.4 and 5.2kW.
These are well-proven laser sources developed exclusively by Bystronic, with the Bylaser 5200 and its ARC technology offering outstanding qualities.
With the aid of the ARC mirror, the laser beam is adapted to the type and thickness of the material, and the beam diameter is kept constant over the whole of the cutting area.
This guarantees the highest level of cutting quality even on the large format Byspeed.
Additionally, both laser sources are able to switch the beam on and off precisely as required, which is a prerequisite for the use of state-of-the-art procedures on the Bystronic laser cutting machines, such as the scanning mode.
Scanning is an innovative method for the linear processing of square and rectangular holes.
These are no longer processed individually, but initially all the edges that lie in the direction of the X axis are cut one after the other.
Subsequently the edges that lie in the direction of the Y axis are cut.
This procedure means that a much higher cutting speed is achieved than when each hole is processed separately and that a cutting performance way above the standard market norm is achieved, which permits the high-precision cutting of 5.5 holes per minute.
And over and above this, Byspeed is not only able to travel along the axes in a straight line, but is also able to move in continuous curves.
The automatic selection of the optimal positioning method takes place based on the cutting direction of the contour.
The arc positioning demonstrates two decisive advantages: Firstly, it permits the positioning speed to be kept constantly high and secondly it is kind to the system, since jerky changes in direction are avoided.
The high precision of the Byspeed also relies on what is known as modulation, which adapts the laser power to the head movement.
If the movement is reduced, for example when cutting detailed contours or during changes in direction, the laser power is also reduced.
This ensures that burned corners and edges can be effectively avoided.
In addition to the high speed, precision and process reliability, Byspeed exhibits impressive dynamism which is based on yet another Bystronic development: What has become known as the DHM drive.
With just a fraction of the magnet area of conventional linear drives, these generate an equivalent drive force of up to 3G.
With their low system costs, the large area of use of the axes and the minimal secondary weights, DHM drives are Bystronic's technologically convincing answer to conventional linear drives.
With the aforementioned characteristics, Byspeed offers optimal conditions for outstanding productivity in the workshop, both now and in the future.
But for Bystronic, the supplying of top-class machines is by no means the end of the productivity trail.
Appropriate potential is also used to the full in respect of the control and the CAD/CAM software and of course in conjunction with the comprehensive solutions for process automation.
This was clearly demonstrated at Euroblech not only by the presentation of the BytransLine automatic loading and unloading system but also by the presentation of the new high-performance ByVision, which represents a milestone in terms of speed and user-friendliness.
On the software side, Bystronic is anyway one of the pioneers within the branch and at the same time one of the very few suppliers whose program package, Bysoft, fully integrates the complete cutting and bending process.
Schuepbach added: "Anyone who with first class machines and on the control and software side, wishes to achieve extensive productivity advances, simply cannot avoid Bystronic.".
