PURPOSE: A surface treatment plate unit for a blasting machine is provided to prevent damage and extend the replacement cycle because an impact is reduced successively through axial holes. CONSTITUTION: A blasting machine comprises spacers(2) which are installed in a rotary shaft(1) of a blasting machine, a plurality of fixing blocks(3) which are alternately installed between the spacers, a fixing plate(5), fixing shafts(4) which pass through the fixing blocks and are coupled to the fixing plate, and a surface treatment plate unit(10) which is installed between the fixing shafts and implements painting of a steel pipe and a steel plate by the centrifugal force of the rotary shaft. The surface treatment plate unit includes an axial hole part guided along the fixing shaft and a striking part(12) formed on a side of the axial hole part.
