A workpiece protecting wire net composed of a spiral spring, and a netting; one end of the spring is formed as a spiral enclosing end, while the other end thereof a hollow openning end, milled workpieces are placed in the chamber of the spring through the opening end, the netting is then put on the spring to have each pitch and the openning end of the spring covered thereby; in a grinding fluid for three dimensional vibration milling in a tank, meshes of the net allow grinding medium and the fluid to penetrate freely so as to adequately transmit a vibration action, and to render the medium and the fluid to grind the surfaces of the workpieces, and to protect the workpieces in the net from collision or tangling with one another, and protection of the spring can be achievced here by the PE netting.
