The sealed cabin robotic laser remanufacturing equipment aims to achieve high-quality restoration. It is equipped with high-precision actuators and various monitoring systems. It is equipped with independently developed offline programming software, which can realize functions such as coaxial powder feeding laser additive manufacturing restoration (for integral discs/blades, combustion chamber casings, shafts, and other parts), laser cladding, and gradient material additive manufacturing. It is also compatible with gas circulation purification systems and sealed cabin structures.
