Laser cladding processing is carried out using a robotic arm equipped with optical fibers and cladding heads. The robotic arm is installed on a moving slide and controls the forward and backward movements of the moving slide, driving the robotic arm to move forward and backward, achieving workpiece cladding processing; The workpiece is fixed on the workbench through the front chuck and the rear center tailstock. The rotation of the front chuck drives the workpiece to rotate, and the tailstock moves forward and backward through lifting.
