Multi-slot antenna double-gas-path vacuum machining tool

The utility model relates to a multi-slot antenna double-gas-path vacuum machining tool, and belongs to the field of high-speed precise milling. Comprising a vacuum chuck body and a metal pressing plate. A main air channel and an auxiliary air channel which are mutually independent are designed on a vacuum chuck body, the main air channel is used for adsorbing workpieces, and the auxiliary air channel is used for adsorbing metal pressing plates and connected to different connectors of a vacuum pump. A workpiece is installed on the vacuum chuck body through the positioning pin and the main path adsorption force provided by the vacuum pump, the metal pressing plate is pressed on the workpiece, and the workpiece is clamped through the auxiliary path adsorption force. According to the utility model, the problem of stable fixation of the workpiece is solved, the barrier-free processing area is expanded, the processing auxiliary time is shortened, and the continuity and the processing efficiency of the panel antenn
