Laser precision processing uses a high-intensity laser beam. After being focused by an optical system, the power density of the laser beam is higher. The workpiece is placed near the focus of the laser beam, and the relative movement of the laser beam and the workpiece is used to achieve heat Processing, the processing accuracy is generally a few microns to tens of microns. The laser beam can be focused to a small size, so it is particularly suitable for precision processing. Including: precision drilling, precision cutting, precision welding.
