毫米波波导器件超声波去毛刺技术的研究

Micro Deburring Technology of Milimeter-wave Waveguide Parts Using Ultrasonic Vibration

毫米波波导裂缝阵天线和毫米波收发组件波导腔体等精密波导器件要求无损伤去毛刺,采用超声波去毛刺方法,对波导裂缝阵列天线和收发组件波导腔体两种典型毫米波精密波导器件进行去毛刺试验,验证超声波无损伤去除毛刺的工艺效果。研究结果表明,在一定的工艺参数条件下,超声波振动120s后可高效去除3A21铝合金和5A06铝合金毫米波波导器件的微细毛刺,实现毫米波波导器件无损伤去毛刺要求,而H62黄铜毫米波波导器件由于材料塑形较高,毛刺与基体附着力强,超声去毛刺效果较差。

This study is focused on the micro deburring technology of milimeter-wave waveguide parts using ultrasonic vibration. The mil-limeter-wave waveguide slot-array antenna and transceiver module cavity are used as the samples for the ultrasonic-deburring experiments.The result shows that most of the burr can be removed for aluminum alloy（i.e., 5A06, 3A21） using ultrasonic vibration after 120 s, which can satisfy the request of milimeter-wave device practicability. While, the deburring result of copper is not obvious, due to its high plasticity and high adhesion between the burr and the part.
