When the ingot is sliced, the ingot is vertically placed on the rotary table 11, and the center line of the ingot is parallel to the downward feeding direction of the diamond wire 8 on the cutting head 41. The distance of horizontal movement depends on the actually required size of the square and the diameter of the diamond wire 8.
