PURPOSE:To perform high accuracy and low cost, by drillng holes for waveguide and fixing at a bundle by wire-cut discharge processing method. CONSTITUTION:A waveguide spacer is provided with a fine slot 3 to tie between a waveguide hole 1 and a surrounding fitting hole 2. In the manufacture of this, a plate having the external shape of a flange is made from a plate having required thickness at first and the prescribed number of plates are overlapped. After setting stacked plates to a wire-cut discharge processing machine, a wire 50 being the electrode of the wire-cut discharge processing machine passes through a hole 5 preset. The discharge processing machine cuts off a flange fitting hole 2, another fitting hole 2 is made, the hole 1 of waveguide is drilled, and so on. Hole processing is made in the above order. |
