  • Patent number: 10067494
    Abstract: A hybrid computer numerical control (CNC) machining center and a machining method thereof are provided. The hybrid CNC machining center has at least a cutting tool head, a laser cladding tool head, a laser surface heat treatment tool head, and a computer numerical control unit. The cutting tool head, the laser cladding tool head, and the laser surface heat treatment tool head are alternately installed in a tool holder of the hybrid CNC machining center. Users can accomplish cutting, laser cladding, and laser surface heat treatment operations for a work-piece just in one single machine, so that the work-piece is unnecessary to be moved between different machines. Therefore, the steps and the process time of the machining operations are substantially simplified.

  • Publication number: 20170304938
    Abstract: A laser cladding tool head and a machined surface sensing method thereof are provided for a computer numerical control (CNC) machining center. The laser cladding tool head has a temperature sensing module and a camera sensing module, which can sense the temperature, lightness, and profile of a molten pool, and then provide them to a computer numerical control unit for a feedback control, so as to increase the processing effect and quality of a work-piece.
