Abstract
A method for slicing wafers from a workpiece includes providing wire guide rolls that each have a grooved coating with a specific thickness, providing a fixed bearing respectively associated with each wire guide roll and providing a sawing wire including wire sections disposed in a parallel fashion. The wire sections are tensioned between the wire guide rolls and are moved relative to the workpiece so as to perform a sawing operation. The wire guide rolls cooled and the fixed bearings are cooled independently of the wire guide rolls.
