Laser fine cuts and drills precisely in 2D and 3D

A new machine generation emerged at EMO for laser cutting and drilling with flexibility, high dynamic response, with acceleration of 1G, and above all high precision.

With its DML 80 Series Lasertec will be presenting a new machine generation for cutting and drilling with flexibility, equally high dynamic response, and above all high precision. The 'supporting columns' of the DML 80 FineCutting and the new DML 80 PowerDrill are the compound table, the linear drives with high dynamic response on the rotary axes, and the solid machine bed of polymer concrete with three-point support to eliminate vibrations during machining, thereby counteracting any restrictions on high precision. The brilliant features of these machines for 2D and 3D laser machining are the high accelerations over 1G, positioning speeds up to 120m/min, and the extreme precision of 10 micron (Pmax).

The modular machine concept with 3, 4, or 5 CNC axes facilitates extremely flexible applications for the DML 80, both for fine 2D and 3D cutting with min widths of 20 micron and for the precision drilling of diameters from 20 micron.

With respect to the choice of laser, the DML 80 proves equally flexible for both drilling and cutting: an Nd:YAG solid-state laser can just as easily be adapted as a CO2 resonator, for laser power outputs from 15W to over 1kW.

Accordingly, the laser can always be chosen for individual quality, speed, and material requirements.

In all cases, the laser is manipulated by the Siemens 840D powerline with integrated laser functions.

As a result, the whole world of CAD / cam systems established on the sector is available.

This optimal overall picture is rounded off by the ease of access to the laser and machining table for simplifying maintenance and the small space requirements of 3.0 x 3.
