The main features of CNC metal laser cutting machine is capable of cutting a very sophisticated graphics, low cut costs due to non-contact cutting, the workpiece deformation is small, good product quality. CNC laser cutting machine laser as an important part, here's how to choose the right CNC laser cutting machine laser.
Cutting thickness <200um selection of metal fiber laser. Beam quality fiber lasers for fine cutting. In such a slit width of less than 20um fine incision, such fine slit, many materials including metals, ceramics, semiconductors such as silicon, and the cutting speed of 10m / min ,. As a result of the high frequency adjustment and laser fast response, fine cutting speed fast, high accuracy and repeatability.
Material pulsed YAG laser for medium thickness or thick cut. JK high power pulsed laser incision width as low as 100μm, cutting thickness greater than 25mm. Pulse YAG laser capable of high precision cutting, because these lasers having high peak power and low average power, can effectively gasify the material, and the heat is small. The material thickness of less than 1mm cutting accuracy of up to 10μm, thicker material cutting accuracy can also go to 25μm.
CW lasers and laser cut JK Super Modulated Continuous width of the range 250-300μm, capable of high-speed cutting 10mm thick metal. Cutting, cutting speed depends on the average power with such a low peak power lasers. Because of overlapping between pulses from such lasers restrictions, cutting relatively thin material it's faster. In addition, there are a number of laser patented super mode, when cutting galvanized steel products, aluminum or surface angled cutting can significantly improve the cutting speed.
