1.High speed high precision high efficiency and low cost. 2. Easy on operation fiber optical path without tediously adjustment on optical path. 3. Compact structure good sealing strongly adaptable to changes in the environment. 4. With the perfect automatic nesting system which can save time save the materials the sheet utilization ratio up to 95%. 5. Moving crossbeam imported high precision racks and linear guide rail stable transmission high precision. 6. Using professional and powerful Shanghai Cypcut fiber cutting controlling system that based on Windows operating system with good Human Machine Interaction and easy operation. 8. Laser is produced without gas and it could use air to cut sheet metal. 9. Machine frame crossbeam and worktable adopt integral welding structure. With stress relief annealing and vibration stress relief treatment it can completely eliminate the welding and processing stress maintaining high strength and precision keeping the normal use of 20 years wi
