[0002] When a diamond tool is used to cut the silicon core, a CNC multi-wire cutting machine tool or similar equipment with a diamond wire saw is used, and a thin steel wire electroplated with diamond particles is reciprocated or moved unidirectionally at high speed on the workpiece to press a silicon rod of a certain diameter onto a wire net formed by the cross-cutting diamond wires of the machine tool, thereby cutting the silicon rod into a thin and long silicon core. This method has relatively low power consumption and high processing efficiency;

[0003] During the diamond wire cutting process, the role of the roller (guide wheel) is to guide and support the high-speed rotating diamond wire to ensure its stability and straightness. However, the contact between the diamond wire and the roller will generate friction, which will not only cause energy loss, but also may affect the cutting quality and tool life. In order to reduce this friction and enhance stability, the rotation of the roller needs to be controlled. The current practice is to equip each roller with a separate motor, but this method increases the complexity of the equipment, increases costs, and increases the difficulty of maintenance.

[0033] During the diamond wire cutting process, the role of the roller (guide wheel) is to guide and support the high-speed rotating diamond wire to ensure its stability and straightness. However, the contact between the diamond wire and the roller will generate friction, which will not only cause energy loss, but also may affect the cutting quality and tool life. In order to reduce this friction and enhance stability, it is necessary to control the rotation of the roller.
