14 enhancements for laser cutting
Highly productive, top quality, process reliability — these useful assistants simply make work easier.
This special cutting system produces the highest quality cuts in thick stainless and mild steel. The smoothness and squareness of the cut edge are far superior to a standard cut. No finishing work is required.
ContourLine makes it possible to accurately cut contoured holes with diameters much smaller than the material thickness. A pulsed beam system controls the introduction of heat into the material.
Sensors keep the distance between the cutting nozzle and the sheet metal constant – even if the sheet is uneven. ControlLine determines the position of the sheet and adjusts the cutting program, eliminating the need to correct the position manually.
The selective cooling of the workpiece during the cutting process allows new geometries and significantly increases process reliability in the processing of thick mild steel.
The intelligent camera system scans sheets in process very accurately and determines their precise position. The machine can also use this data to detect parts which have already been cut, in order to process them further and with absolute precision. In addition, DetectLine automatically adjusts the focus position.
6Single cutting head strategy
Save time by using a single cutting head that does not require changing. This reduces non-productive time, especially when you are automatically processing a number of different materials.
The cutting head travels at high speed over the entire sheet line by line. The control system cuts all the contour sections in the respective beam path. This reduces the time spent on traversing and positioning, especially when cutting perforated grids.
An adaptive mirror in the beam guidance system makes it possible to automatically adjust the focus position to the material type and thickness. The result: Maximum processing speed and excellent edge quality across the entire range of surfaces and materials – without the need for manual adjustment.
A special cutting head selectively introduces metal vapor plasma to significantly increase cutting speed.
10Laser output control
The laser power output is automatically adapted to the cutting speed. This ensures optimum cut quality even on sharp corners and small contours.
LensLine immediately switches off the beam if the focusing lens accumulates a critical amount of debris. This prevents the lens from thermally decomposing and keeps the beam guidance system clean. The system automatically checks the condition of the lens in the mounted cutting head. So the lens is only cleaned when necessary – not just as a precaution.
This technique introduces nitrogen at very high pressure to produce oxide-free edges. As a result, you can cut thicker sheets and achieve very high cutting speeds in stainless steel and aluminum.
PierceLine monitors and controls the piercing process. This reduces stress on the material and machine and shortens pierce time by up to 80%.
If plasma forms when thick sheets are being cut, the control system reduces the feed speed or stops the axis motion. The beam is not interrupted, meaning PlasmaLine ensures high process reliability and part quality.
