How to thread the wire close to the original processing point (in the slit) after the wire is interrupted during fast wire cutting

There are two important points. First, the molybdenum wire must be straight, and second, the diameter of the molybdenum wire must be thinner than when the wire is broken. If these two points are achieved, the chance of successful repeated threading will be greater. In order to achieve the first point, you can straighten the molybdenum wire, then burn it with a lighter, and loosen it after cooling. This is equivalent to tempering the molybdenum wire as it is straightened. After this treatment, the molybdenum wire will be straighter and not easy to bend. Grinding the molybdenum wire with sandpaper can reduce its diameter, but be careful to grind it with finer sandpaper to ensure the second point. The sequence is to polish first and then straighten. If it cannot be penetrated, the workpiece position can only be manually shaken out, and reprogrammed to allow the molybdenum wire to re-cut outside the contour of the part.
