Abstract:
A method for simultaneously cutting off a multiplicity of wafers from a hard, brittle workpiece which has a longitudinal axis and an outer peripheral surface comprisingguiding the workpiece by a relative translational movement, directed perpendicular to the longitudinal axis, between the workpiece and a wire web of a wire saw with a feed device, through the wire web which is formed by a sawing wire;rotating the workpiece about the longitudinal axis while the wafers are being cut off; andholding the workpiece by spindle sleeves at beginning of cutting off the wafers and holding the workpiece by rollers at end of the cutting off of the wafers; andthe spindle sleeves clamping the workpiece axially and the rollers supporting the workpiece on the outer peripheral surface.
