Wire EDM Wire Cutting Tips

For the first important process of WEDM, the author has been engaged in WEDM teaching for many years to summarize some of the threading techniques.

1. To maintain a certain tension in the process of silk loading, the molybdenum wire should be held by hand to maintain a certain tension during the process of silk packing. If there is no tension, the filament yarn will squish and the yarn will slip out of the guide wheel.

2, the silk into the wheel mounted molybdenum wire should be set in the guide wheel, to avoid friction and wear of the molybdenum wire and rack damage to the frame, while reducing the life of the molybdenum wire.

3, there must be enough silk long-line cutting process in which the silk tube is a kind of reciprocating motion silk tube packing width should be at least one-half of the width of the tube is slightly smaller than the width of the tube.

4. After the wire is wound and tensioned with the vertical electrode wire of the workbench, the verticality of the electrode wire to the worktable should be taught and adjusted. In the production practice, simple tools are mostly used. (such as a square ruler, a cylindrical ruler, or a regular hexahedron), with the work surface (or the jig table placed on it) as a benchmark, visually measure whether the gap between the electrode wire and the surface of the tool is the same, and adjust it until the gap is consistent from top to bottom.

5, after the wire is installed, it is necessary to re-tension the general EDM wire-cutting machine tools have molybdenum wire tensioning device. For the wire-cutting machine tool with no tensioning device on the wire frame, the wire must be tightened with the hand wheel before processing.
