Abstract:

A wire saw machine having a wire supply source providing a plurality of strands of wire results in a wire saw system having parallel wires. The wire supply source feed spindle holds a supply source at a slight angle advance to allow the wire to transfer from the supply source to a grooved wire guide in a parallel manner. Two moveable wire guides are used to impart a back and forth motion to the wire over the cutting area and at the same time serve as an intermediate storage area for the wire being used in the cutting area. The wire supply source includes a plurality of individually rotatable wire reels. A friction disc is located between each of the individual wire reels and is held fixed with respect to the spindle.
