Abstract

PROBLEM TO BE SOLVED: To provide ingot cut pieces with small warping by traveling a wire twisted plural times during from the time when the wire is supplied from a delivery reel and till it is wound by a winding reel. SOLUTION: The number of twisting of a wire 3 during the time after the wire 3 is supplied from a feeding reel 2 and till it is wound up by a winding reel 6 is determined on the basis of the angle of valley, position of a virtual point for dividing a bottom side, the number of groove, wire diameter, and the number of roller 4 provided with a groove having a triangle cross section except for the isosceles triangle. This number of twisting is set at 2-10, desirably at 2-5. In the case where the number of twisting of the wire 3 is large, the wire 3 becomes easy to be cut. On the other hand, in the case where the number of twisting is small, abrasion of the wire 3 is increased to shorten the lifetime of the wire 3, or not to obtain such an ingot cut piece as unevenness of the distribution of thickness is small.

[0003] In the method of cutting an ingot using a working fluid (free abrasive grains) in which abrasive grains (diamond abrasive grains, copper powder, silicon oxide powder, glass powder) are dispersed in water or the like, the free abrasive grains used for cutting are used. In addition to the disadvantage that the abrasive grains are scattered on the work table and dried to contaminate the working environment, waste liquid treatment and washing of the cut ingot slices are required. As a means to solve the above-mentioned drawbacks of cutting ingots (including silicon, ceramics, glass, etc.) using free abrasive grains with a wire saw, diamond abrasive grains and copper powder are adhered to a wire (piano wire) with a thermosetting resin binder. It has been proposed to use a wire to which solid abrasive grains that have been heated and hardened are adhered ("1997 Precision Engineering Society Spring Academic Conference"; held March 18, 1998). The method for cutting an ingot using the solid abrasive wire tool improves the above-mentioned disadvantages of loose abrasive grains.

However, since the abrasive grains are fixed to the wire, the fixed abrasive grains and the wire at the same location always contact the ingot by the reciprocating movement of the wire (see FIG. 4), and the wear of the abrasive grains and the wire is reduced. Intensely, where the abrasive grain hits the ingot and where the wire piano wire hits the ingot, the thickness difference between the sliced ingot pieces is large, and the sliced ingot pieces may warp. It has been found that there is a disadvantage that the amount of grinding and polishing is increased. Further, when the reciprocating movement of the wire requires a cutting speed of 0.02 to 2.5 mm / min before cutting the ingot, it takes as long as 6 to 20 hours.

[Function] When cutting the ingot, the fixed abrasive wire is 2
Since the ingot is cut by being twisted or untwisted by about 10 to cut the ingot, unlike the conventional wire saw apparatus using a roller having an isosceles triangular cross section, as shown in FIG. 5, the wire and the ingot come into contact with each other. The location is different when the wire reciprocates and the wear of the wire is evenly performed, so that the life of the wire is prolonged, and the thickness distribution of the cut ingot piece is small, and the warp of the ingot piece is small.

Before and after the book. When the fixed abrasive wire contacts a groove having a triangular cross-sectional shape other than an isosceles triangle, the length of the right side 4c and the length of the left side 4d of the groove are different, so that the wire 3 comes into contact with each groove until it crosses one roller. It is gradually twisted. It was sent from the reel 2 for delivery according to the angle of the valley (θ), the position of the virtual point A dividing the base, the number of grooves, the wire diameter, and the number of rollers having grooves having a triangular cross-sectional shape other than an isosceles triangle. The number of times the wire 3 is twisted before the wire 3 is wound on the winding reel 6 is determined.

5 times. If the number of twists of the wire is large, the wire is likely to be cut. On the other hand, if the amount is too small, the wire wear will be large and the life of the wire will be short, and an ingot cut piece having a small variation width of the thickness distribution, which is an effect of the present invention, cannot be obtained. Here, the number of twists refers to the number of times the point A of the wire is rotated around the axis of the wire before the point A of the wire is sent out from the sending reel and wound around the winding reel.
