Processing method of large-caliber hypersonic wind tunnel honeycomb

The invention discloses a processing method of a large-caliber hypersonic wind tunnel honeycomb. The machining method comprises the following steps that honeycomb position round holes of a honeycomb device are machined, a special array type electrode device is manufactured, and an electric spark machine tool spindle is fixedly connected with the lower surface of a tool base of the array type electrode device; and a honeycomb is manufactured by electrical discharge machining using an array electrode arrangement. According to the machining method of the large-diameter hypersonic wind tunnel honeycomb, the manufacturing problem of the large-diameter hypersonic wind tunnel honeycomb is solved, and the manufactured hypersonic wind tunnel honeycomb is good in strength, small in deformation and capable of meeting the use requirement of a hypersonic wind tunnel. The processing method of the large-diameter hypersonic wind tunnel honeycomb is simple in step, high in machining efficiency and reliable in work, and can be
