The application of metal laser cutting machine, metal laser cutting machine is divided into small and medium power and high power cutting machine. Small and medium power cutting machine individual under 1000W, the price is absolutely cheap, the thickness of cutting metal individual will not exceed 10 thick. And high power laser cutting machine individual in 1000W or even a few kilowatts. Cutting thickness, the price is relatively high, individual only large manufacturers such as automobile parts processing. Metal laser cutting machine individual small and medium power metal cutting machine can cut 1, carbon steel plate cutting. Modern laser cutting system can cut the maximum thickness of carbon steel plate close to 20mm, the thin plate of its slit can be narrow to about 0.1mm. Laser cutting of low carbon steel, the heat affected zone is very small, and cut on flat, lubricated, good verticality. Metal laser cutting machine for high carbon steel, laser cutting edge quality is better than low carbon steel, but its heat affected zone is larger. Metal laser cutting machine laser metal series maximum cutting depth of 10mm. 2, stainless steel cutting. Laser cutting is easier to cut stainless steel sheet. The maximum thickness of stainless steel cut by high power YAG laser cutting system can reach 4mm. We developed a small power YAG laser cutting system cutting stainless steel thickness up to 4mm. 3, alloy steel plate cutting. Most alloy steels can be laser cut with good edge quality. However, tool steel and hot die steel with high tungsten content will have corrosion and sticky slag when laser cutting. 4, aluminum and alloy plate cutting. Aluminum cutting belongs to melting cutting, metal laser cutting machine to be assisted by gas to blow away the molten cutting area, can achieve better section quality. The current maximum thickness of the cut aluminum plate is 1.5mm. 5, other metal material cutting. Copper is not suitable for laser cutting, cutting very thin. Most titanium and titanium alloys, nickel alloys can be cut by laser. Non-metallic materials.
