Large application profile laser cutting machine has acquired the international advanced DSP control technology. It is the first tool to use the quick constant curving-cut and in a short processing features. At the time of operation, the device automatically keeps the light stable so that the cutting effect remains the same for each spot. Fast cutting controllers and moderate functioning in high-speed motion increases the operation efficiency. USB port is used to transmit data, equipped with large-capacity memory, improving working efficiency greatly .Software like CAD, CAM of CAD, and CorelDraw ensures direct and clear output of real pictures to meet the required design of users. . The machine can store large of amount of data in the storage capacity and for transmitting those data a USB port is provided within the system.
