采用压缩空气吹屑,所用工具结构简单,也能较好地清除各类机械零件孔穴中残留的微小切屑,但对小而深的盲孔则效果很差,切屑吹不干净。为此我们设计制造了一种专用的回旋风吹屑器。它由圆锥管接头和旋风头两部铜焊成一体。利用0.5MPa(5kgf/cm~2)压缩空气,由进风口导入旋风头内孔,并从出风口吹向盲孔底部,迫使压缩空气沿着回风导向槽剧烈旋转, The use of compressed air blowing debris, the tool used in a simple structure, but also better able to remove all kinds of mechanical parts of the hole in the tiny residual chips, but the small and deep blind hole is ineffective, the chip blowing is not clean. To this end, we have designed and manufactured a special cyclone wind Dryer. It consists of a conical pipe connector and a torus head of two brazed into one. Using 0.5MPa (5kgf / cm ~ 2) compressed air from the air inlet into the cyclone head hole, and blown from the outlet to the blind hole bottom, forcing the compressed air along the return air guide groove violent rotation,
