Abstract:
The present invention relates to a processing method of wire material and a processing device therefor at the times of intending to make the tip of wire materials such as guide wire for catheter thin and flexible by tapering.When the wire material passes through the electrolytic tub, the wire speed is made constant and the current value is controlled, or the current value is made constant and the wire speed is controlled to give the processings such as tapering. For the electrolytic polishing bath, it is desirable to use a mixed bath comprising trivalent alcohol, perchloric acid and monovalent alcohol.The inventive method exerts an effect that the tapering can be given efficiently and yet with high precision compared with the traditional method of mechanical polishing or the method of dipping one by one batchwise into the electrolytic polishing bath.
Abstract:
A micromelt structure is provided on a probe tip by contacting the probe tip with a foil of the material from which the micromelt structure is to be formed and passing an electric current through the contact point to melt the foil and cause the molten foil material to collect on the tip of the probe where, by surface tension, it is drawn into a microsphere shape and homogeneously solidifies. The probe with the micromelt tip is highly reproducible and uniform and is particularly effective for use as a probe in scanning microscopy.
Abstract:
Probe tips are produced from electrically conductive wire by electrolytic machining of a zone of the wire above a free end utilizing a liquid electrolyte layer in contact with this zone, a ring electrode surrounding this zone, and a layer of an insulating fluid into which the free end extends. The insulating fluid can be air where the electrolyte is a membrane between layers of air above and below the membrane, or a body of a liquid insulator below the electrolyte layer where the insulator and the electrolyte form a bath.
