Problems solved by technology

[0008] 2) The material has high plasticity and difficult finishing;

The cavity design of millimeter wave components requires strict symmetry and coaxiality. The design basis is mostly the geometric center of the waveguide cavity. In most cases, due to the limitation of processing technology, the center positioning cannot be used for clamping, and only the outer surface can be used. These indirect machining benchmarks are used for positioning and clamping, and this clamping method has errors relative to the design benchmarks

In addition, due to the large number of processing parts, multi-step and multi-process processing are required, and it is difficult to maintain consistent benchmarks, which will lead to poor part processing reliability, low production efficiency, unstable quality and low yield

[0012] 4) The integrity requirements of the waveguide cavity are high

In order to ensure the integrity of the cavity, it is often necessary to use special processing equipment such as EDM and wire cutting. It is necessary to make different electrodes and clamping tools for different cavities, which increases the production cycle and increases the manufacturing cost.
