如角向磨光机、钢丝刷、风动针束除锈器、风动敲锈锤、齿型旋转除锈器等，属于半机械化设备，工具轻巧、机动性大，能较彻底去除锈、旧涂层等，能对涂层进行打毛处理，效率比手工除锈大大提高，可达1—2m2h，但不能除去氧化皮，表面粗糙度较?

可在任何部位使用，特别在修船过程中得到广泛应用
2抛丸机(砂)除锈主要以颗粒喷射冲蚀作用构成的以达到表面清洁和适宜的粗糙度，设备包括敞开式喷丸(砂)除锈机、密闭式喷丸(砂室)、真空喷丸(砂)机
敞开式喷丸(砂)机应用较为广泛，能较为彻底地清除金属表面所有的杂质，如氧化皮、锈蚀和旧漆膜，除锈效率高4—5m2h，机械程度高，除锈质量好
但对由于磨料一般不能回收，对其他作业有影响，清理现场麻烦
所以环境污染较重，近来逐渐被限制使用
3高压水磨料除锈利用高压水射流的冲击作用(加上磨料的磨削作用)和水撬作用破坏锈蚀和涂层对钢板的附着力
其特点是无粉尘污染，不损伤钢板，大大提高除锈效率，可达15m2h以上，除锈质量好
但除锈后的钢板易返锈，须涂装专门的带湿除锈涂料，对一般性能涂料的涂装有较大影响
