The invention relates to a coaxial metal shielding layer wire stripping machine which comprises a laser source, a galvanometer scanning system, an annular optical reflector and a mechanical device. The machine is characterized in that laser transmitted by the laser source is expanded and collimated by a beam expander, and then passes through a X-direction galvanometer, a Y-direction galvanometer and an F-THETA lens to spatially form a tapered optical path which passes through the annular optical reflector and focuses on a focus to form a focus circle with a certain diameter. The focus circle performs annular stripping on the coaxial metal shielding layer with the same diameter. The machine has novel idea, reasonable design and normative process, can realize effective stripping of the coaxial metal shielding layers of different sizes, and is characterized by fast processing speed, thorough stripping, high yield and high production efficiency. The machine can be widely applied to processing various large-sized coaxial metal shielding layers.
