At present, the beam of laser cutting machine mainly has the following structural forms: steel plate welding beam, high requirements for welding and heat treatment at various stages, large cross-section of beam, thick steel plate, The beam is too heavy and the dynamic response is poor, which indirectly leads to an increase in the selection of the drive motor and increases the cost. The cast aluminum alloy beam is currently used by many laser cutting machine manufacturers, but is limited by the fluidity requirement during casting. The selected aluminum grades are lower, the mechanical properties of the materials are poor, and casting defects (such as shrinkage cavities, etc.) are many. At present, the thinnest casting thickness in China is 12mm, and the weight of the beam is difficult to continue to be reduced. The aluminum plate is welded to the beam to obtain reasonable cross section and strength.
