The shape memory alloy substrate and the polishing member are moved together by a driving means, and the temperature of the shape memory alloy substrate is adjusted during polishing, so that the shape memory alloy substrate and polishing member are moved according to the various curvatures of the surface to be polished. Since the shapes of the substrate and the polishing member can be changed, polishing can be performed with the polishing member matching the surface to be polished of the object to be polished. Therefore, when polishing objects with various curvatures or surfaces with different curvatures, it can be done with a small number of polishing tools, and there is no need to replace the grindstone each time, greatly improving work efficiency. do. Furthermore, the cost and time spent on manufacturing the polishing tool can be reduced, resulting in an extremely economical polishing tool.
