巻取リローラ（８）に巻取られる。By the way, the above steel wire (material) (1) is in the electrolytic polishing liquid tank (5).
) The conditions for electrolytic polishing, such as the speed at which the polishing material passes, are controlled by a program relating to time and linear velocity as shown in FIG. In other words, the time required for passing through the electrolytic polishing liquid tank (5) is shortened (high speed).
By doing this, the amount of polishing and melting of the steel wire (1) can be reduced, and by increasing the time required for passing through the immersion (lower wire speed), the amount of polishing and melting of the steel wire (1) can be increased and the desired taper can be achieved. It is done. The steel wire (1), which has been tapered as desired, is then sequentially washed with water and subjected to rust prevention treatment.

。Therefore, polishing of steel wires is carried out using a combination of chemical polishing etching (corrosion) and electrochemical polishing etching, and it is possible to polish steel wires in a short time without maintaining the electrolyte at a temperature of several tens of degrees Celsius. The vines are polished. In this way, the electrolytic solution is easy to handle (because it does not need to be kept at a high temperature), and the risks associated with processing operations are reduced, while a practically sufficient yield can be achieved. Moreover, in the method of the present invention, the tapering of the steel wire by polishing progresses through the coexistence of some chemical polishing and electrochemical polishing, and in particular, electrochemical polishing, which corresponds to forced polishing, is performed by, for example, chemical polishing. Protrusions that tend to occur or remain on the surface are polished and corroded in a straight line, so a smooth surface can be easily formed. That is, compared to the taper wire manufactured by chemical polishing ζ using a pyrophosphoric acid solution, the taper wire manufactured by the method of the present invention has a better surface smoothness and an excellent appearance. This good surface smoothness is an important advantage since this type of Taber wire is used for drilling fine holes of, for example, about 0.2 xz or less, and high precision is required.
