It is a laser cutting machine with high efficiency and upper segment standards. Can carry up to 30.000 W laser power, so cutting some thick plate, it is a very good choice. For agricultural, textile machinery, food machinery construction machinery, lift manufacturer and other large machinery and equipment manufacturing, usually use FLC fiber laser cutting machine for processing. It is an ideal cutting machine for those who will outsource. Provides easy use blowing, cutting, pause, calibration simulatione, etc. with its wireless remote control. Standard nesting software program, it makes the parts to be cut ready for cutting very quickly without the need for an operator. It also has flycut cutting feature. Since it is a double exchance table, you can continue cutting without waiting. All of our machines are produced in European standards and we have a CE certificate. Our FLC type machines have nozzle cleaning and double camera system. There are 1.5x3 mt, 2x4 mt or 2x6 mt cutting area options. Our laser head has auto focus and Active Anti-collision Function an auto view feature that detects obstacles and moves automatically. Cutting heads have automatic cooling. The bridges we use in all our machines are made of aluminium alloy sheet-plate welding construction type and one piece. The fact that it is one piece ensures that the bridges are rigid and prevents the bridge from maintaining its form and deforming in case of impact, overlap or strain that may be encountered. In addition, thanks to its 3 times lighter structure compared to steel profile bridges, we can output high speeds and accelerations at lower engine Powers.

Depending on the requirements and the workpiece, this is then pressed through a nozzle with a diameter of 0.01 to 0.08 mm. Since water jet technology processes materials without heat input, there are no deformations. By adding an abrasive, water jet cutting enables maximum precision with tolerances of +/- 0.01 mm. Our flexible production allows vertical as well as diagonal cuts. We would be happy to receive your individual CAD data. The water jet technology offers great advantages for industry, trade and individual prototype production. Water cutting technology is also a plus point for the environment, as it works dust- and steam-free and also saves material. Waterjet Cutting: Example Gallery What sounds impressive in theory is even more impressive on the finished object. We have put together a selection of images to demonstrate our waterjet cutting capabilities. Click through the photos in the example gallery and get an impression of what is possible with this modern processing method.
