Therefore, the existing cutting mode of the annular diamond wire is adopted, and the silicon rod is damaged more when the silicon rod is cut to the tail part in a single monocrystalline silicon rod cutting mode (horizontal mode).

When the circulating diamond wire cutting mode works, the diamond wire does high-speed motion and reciprocates forward cutting and reverse cutting. When the direction is reversed, the routing inevitably goes to zero from a high-speed state and then is accelerated to the high-speed state, and the reciprocating motion is carried out, so that the cutting speed is slowed down, and the cutting efficiency is influenced. The processed monocrystalline silicon bar has high surface roughness and large workload required for subsequent grinding. The circulating wire has more transition wheels from the diamond wire winding drum to the cutting area, and the influence caused by accumulated errors is more. And the edge breakage phenomenon can be caused when the horizontal cutting mode is adopted and the end of the monocrystalline silicon bar is cut, and the edge breakage part is accumulated loss for production.
