This utility model relates to the field of silicon core cutting technology, and particularly to a wire steering module, including a first steering assembly for cooperating with at least two sets of adjacent guide wheel modules for wiring. Wire I enters through the first steering assembly, then proceeds through the first guide wheel assembly to a set of guide wheel modules for wiring, then through the second guide wheel assembly to another set of guide wheel modules for wiring, and finally exits through the first steering assembly. This utility model has one steering assembly corresponding to two sets of guide wheel modules, enabling wiring for two sets of adjacent guide wheel modules. For a cutting table with six positions, only one wire steering is required, which shortens the overall wiring length compared to two steering operations and reduces the risk of diamond wire breakage.
