WIRE SUPPLYING AND RECEIVING DEVICE FOR A WIRE SAW, INGOT SLICING WIRE SAW INCLUDING THE SAME, AND METHOD OF SLICING INGOT

摘要

A wire supplying and receiving device (4) includes a moving unit (41) including a rail (411) along a first horizontal direction (X), a first wire winding unit (42) disposed on the rail (411) and rotatable about an axis (LI) parallel to the first horizontal direction (X), and a second wire winding unit (43) on the rail (411) and rotatable about the axis (L1). At least one of the first and second wire winding units (42, 43) is movable along the first horizontal direction (X). The wire supplying and receiving device (4) is convertible between a connected state, where the first and second wire winding units (42, 43) are adjacent to each other, and a disconnected state, where the first and second wire winding units (42, 43) are spaced apart from each other. An ingot slicing wire saw (100) and a method for slicing ingot are also provided.
