Abstract

The invention discloses a double-line-belt laser-electrolysis composite milling machining system which comprises a workpiece, a circulation and power system, a double-line-belt laser beam system and a composite milling cutter head. The laser beam system forms focusing line band laser with adjustable spacing and length through a beam splitter, a reflection cavity and a shaper, and the composite milling cutter head realizes uniform injection of electrolyte and shielding of an electric field through an electrode core with an array micro-flow groove, a conductive grid mesh and a suction device with a flexible insulating wall. The temperature of a machining area is increased through laser thermal activation, the electrochemical reaction activity is enhanced by cooperating with the electrolysis effect, the reaction area is limited through the insulating wall, a boundary electric field is shielded, and a multi-energy-field coupling mechanism is formed. Double-line-band laser can expand energy field coverage, and the machining efficiency and the surface quality are improved by combining electrolyte laminar flow and electric field uniformization design; the non-contact combined machining avoids deformation of large thin-wall components, and is suitable for high-quality and high-efficiency machining of large-format components in the fields of aerospace and the like.
