PROBLEM TO BE SOLVED: To achieve labor saving by mechanizing polishing work of a turbine blade by a wire brush. SOLUTION: An object to polish is held by a fixed holding mechanism 20 and is sent by a reciprocating feeder mechanism 30 together with the fixed holding mechanism 20, and it is controlled by a control device 60 that its both sides are polished by wheel brushes 41, 41 on both sides of a feeding direction, it is also polished from the above by a rotating wire brush 51 and the object to polish can be polished by the wire brushes 41, 41, 51 during one round trip. Therefore, removal of masking material of a turbine blade can be mechanized, so that working time can be shortened and labor saving can be achieved. |
