ake your heavy-duty fabricationsoperations more productiveand profitable with advanced

laser cutting technology fromLVD, a leading manufacturer ofmetal fabrication equipment.

Our line of heavy-duty Impulslasers addresses the special needsof plate fabricators.

We've advanced such features asrotary axis cutting and introducedthe powerful Fanuc 6 kWresonators to our Impuls lasersystems for fast and accurateprocessing of a range of materialsand material thicknesses, includingstainless steel, plate and wear andstructural plate such as Hardox,Weldox, Domex and others.

Impuls Series lasers offer largetable capacities to handle materialsup to 12500 x 3000 mm and theflexibility to process flat plate orload the table while processingpre-formed parts or tubes.

FeaturesDesigned forProductivity

� Plasma detection continuouslycontrols the cutting process. Incase of a cutting failure, plasmawill occur and the system willeither slow down, or stop andactivate the retry function. Thisallows unmanned processing ofstainless steel and aluminum,higher cutting speeds, andhelps reduce scrap

� Capacitive height sensingbuilt into the cutting head:• Maintains a constant distancebetween the head and thematerial being processed

• Adjusts to any undulationsin the plate

� High pressure (clean cut)cutting head (standard)equipped for a 5", 7.5" or 10"cutting lens

� Built-in scrap conveyor

Impuls lasers achieve highproductivity and accuracy bycombining high axis speeds withoptimal cutting conditions over theentire cutting area, using a uniqueconstant beam length system.

In most machines, the divergenceof a laser beam is compensated byuse of a telescope and/or adaptiveoptics.With these systems, however,a variation in cut quality over thecutting area can occur becauseof a change in the focal positionand/or focal spot size.The constantbeam length system of the Impulseliminates the divergence of thelaser beam, ensuring identicalresults over the entire cuttingarea, at optimal speeds, withsuperior edge quality.

The edge function featurefacilitates cutting sharp corners,particularly in thicker plate.

A unique beam length compensation system eliminates thedivergency of the laser beam, ensuring identical cutting resultsat any location within the cutting area at optimal speed.

Laser Package

All LVD lasers systems featurethe Fanuc laser package.

Fanuc, global market leaderin CNCs and drive mechanisms,is a major supplier of laser systemswith over 10000 units sold. Thecompany produces a custompackage solution for LVD thatdelivers important benefits forlaser systems users.

The Fanuc laser package includesa laser, CNC controller, and digitalservo drives.The package gives theuser full control over the cuttingprocess with the most reliabletechnology in the world. End-users benefit from integralinterfaces, easy installation andstart-up, and a host of additionalfunctions that make laserprocessing more economical.

Impuls systems use a 4 or 6 kWfast axial flow high power CO2

laser with high frequency (HF)excitation utilizing MOSFETsemiconductor technology. Highfrequency resonators are universallyaccepted as extremely reliableand maintenance friendly. Thereis no need to change electrodesdue to erosion or because ofcontamination. These lasers alsoprovide extremely economicaluse of laser gas (10-20 l/H). Allresonators feature the latest radiofrequency excitation technologyfor high reliability.

Flexibility is the key to productivityin laser cutting.With the capabilityto process flat plate, pre-formedparts and tubes, the Impuls 4020-Roffers the highest level of flexibilityavailable in the market today.

The standard configurationprovides two shuttle tables anda 280 mm fully programmableZ-axis for use with a rotary axisor for processing pre-formed parts.The shuttle table allows the userto load/unload one table whilethe machine processes flat plateor load the table while processingpre-formed parts. Changeoverfrom flat sheet to rotary can beachieved within seconds.

The Impuls 4020-R processeslarger diameter tubes (up to500 mm) and pre-formed partsthan any other system and is theonly machine of its type tocombine rotary and flat platecutting with ease for the ultimatein processing flexibility.

The Impuls 4020-R processes tubesup to 500 mm diameter with aweight of 950 kg. Even whenprocessing a single part, the 4020-Ris the ideal tool, since flat sheetcutting can continue during rotaryset-up or loading/unloading ofthe tubes.
