Finest contours cut at speed with high precision

A flexible precision laser machine with high dynamic response is believed to be the world's first of its type with high dynamic response for precision 2D and 3D cutting, welding and drilling.

Lasertech has introduced its DML 80, the world's first series laser machine with high dynamic response for high precision 2D and 3D cutting, welding, and drilling Based in Kempten, Lasertech has now channelled into a further impressive innovation its many years of experience gained from laser application technologies. At euroblech in Hannover, this subsidiary of Deckel Maho presented the DML 80 series as a new machine generation for the flexible, highly dynamic, but above all highly precise cutting and drilling of sheet metal between 0.1 and 3.0mm. The extreme machine precision of 10micron (Pmax), high positioning speeds up to 120m/min, and accelerations up to 2G are only a few of the impressive features that this innovation has to offer.

The 'supporting pillars' of this concept are in particular the X/Y-axis compound table with highly dynamic linear drives and the solid machine bed of polymer concrete on the tried-and-tested three-point support.

The result is vibration-free, and therefore the highest possible precision for all machining operations.

The DML 80 also proves impressively flexible in the choice of laser source: an Nd:YAG solid-state laser can be integrated just as easily as a CO2 system.

Accordingly, the laser type and power can always be configured to the respective requirements placed in each and every case on quality, speed, and material.

For all applications, the laser is manipulated directly via the Siemens 840D powerline, whose full potential is accessed from an ergonomic stainless steel operator console with 17in TFT screen.

At the same time the CNC controller is, so to speak, an 'old hand' in laser applications, and ensures from the outset that the operator can access the whole range of CAD/CAM systems established on the sector.

This optimal overall picture is rounded off by the small space requirements of 3,0 x 3,5m and the ease of servicing facilitated by a walk-on column for fast access to the laser.

The modular machine concept with 3, 4, or even 5 CNC axes makes the DML 80 ideal for extremely flexible applications both for fine 2D and 3D cutting and for laser drilling and welding applications.

And not least of all, the wide range of potential applications means that the offer can be easily configured to the specific requirements of a great many sectors, whether the automotive, electronic, or aerospace industries.

But also every smaller laser job shop will find that the DML 80 is the perfect complement to its conventional machinery stock: with investment costs of just under 250.000 euros for the complete machine including the YAG-laser the price-performance ratio proves an especially attractive incentive.

With its technical features and the support of DMG as a global marketing and service company, the DML 80 precision laser machine undoubtedly has everything needed to become a global trendsetter.
