Abstract:
A wire guide for a wire saw used for slicing cylindrical workpieces, comprising:a cylindrical substructure capable of being engaged by a wire saw drive mechanism and rotatable around an axis, said substructure having a first thermal coefficient of expansion, and said substructure having a body and flanges at each proximal end of the body having a greater diameter than the cylindrical body of said substructure; and an outer sleeve attached to said substructure having an outer diameter, said outer sleeve having a second thermal coefficient of expansion greater than the thermal coefficient of expansion of said substructure, wherein said outer sleeve is bounded on each proximal end by the flanges of said substructure such that axial thermal expansion of said outer sleeve is constrained by the flanges of said substructure, and wherein the flanges of said substructure have a diameter equal to or larger than the outer diameter of said outer sleeve.
