放在露天的钢板和铁皮,在划线前或喷漆时,需要擦去表面层上的铁锈,灰尘和氧化层,过去这些工序大都是靠手工来完成,效率低,劳动强度大,而且还要浪费很多砂布和棉纱。现在我们采用普通摇臂钻、立钻、台钻、手电钻带动钢丝刷除锈的办法(附图示),使用效果良好。 Placed in the open steel and metal, before marking or painting, you need to wipe the surface layer of rust, dust and oxide layer, in the past these processes are mostly by hand to complete, inefficient, labor-intensive, but also Wasting a lot of emery cloth and cotton yarn. Now we use ordinary rocker drilling, vertical drilling, bench drill, hand drill driven wire brush rust (with picture), the use of good results.
