<p>A wire saw 110 comprises a wire 114 extending between two reels 112, 126 and guided around a plurality of grooved rollers 122 to form wire rows 124, the wire rows 124 being treated with a solution 140 containing abrasive grains and adapted to contact a workpiece 154 in order to cut the workpiece 154 into a number of thin wafers. At least one of the reels 112, 126 and grooved rollers 122 is connected to a rotary shaft of a driving motor 128, 130, 132 for driving said at least one of the reels and grooved rollers coaxially with said rotary shaft. The motor may be formed integrally on a frame of a main body of the wire saw. A turntable 170 may be connected to said rotary shaft 162 of said motor coaxially with said rotary shaft, said turntable 170 being connected to said at least one of the reels 112, 126 and grooved rollers 122. <IMAGE></p> |
