The fully automatic depaneling machine, also called a circuit board cutting machine, uses a high-speed rotating spindle to drive a milling cutter for cutting. It can cut substrates with high-density plug-in components, and cut PCBA boards and other substrates made of other materials accurately and at high speed. The operation process is as follows. Install the circuit board and place it on the processing platform for cutting. With high precision and safety, the high-speed spindle ensures cutting of circuit boards with minimum cutting stress; the dual-platform design works interactively to reduce loading and unloading time and improve production efficiency. The unique dust suction structure ensures the cleanliness of the circuit board. Up suction and down suction are optional, providing customers with options for multi-faceted applications. The machine operation is humane and intelligent. It is assisted by CCD camera, intelligent copying, and cutting path optimization algorithm to ensure high precision and efficiency of the machine. The Windows 7 window operating system is safe, stable, easy to learn and use.
