Under normal circumstances, it in the U-shaped waveguide processing of 8 millimeters of radars, had both needed using high-accuracy machining tool, it is also necessary to use high-grade
Operator, while because its processing quantity is larger, so that its difficulty of processing increases, processing matter is also easy to appear in its process
Amount problem.Thus have led in the process of 8 millimeters of U-shaped waveguides of radar, easily occur yield rate is low, the process-cycle is long,
The problems such as processing cost substantial increase.
The utility model devises 8 millimeters of U-shaped waves of radar particular for the actual conditions of the U-shaped waveguide processing of 8 millimeters of radars
The processing tool led, to reach using simple and easy method, reached both quickly, also ensure that critically to process 8 millimeters of radars U-shaped
Waveguide, while the process-cycle is also greatly lowered and improves processing quality, and can be reduced the reduction of processor's grade again, and reach
It can guarantee that 8 millimeters of U-shaped waveguides of radar can high efficiency, in high quality production and complete symbol when being processed using conventional equipment
Design requirement is closed, and by technique and examines the purpose approved.
