<p>24 Abstract:Apparatus and method for simultaneously slicing a multiplicity of slices from a workpiece5Apparatus and method for simultaneously slicing a multiplicity of slices from a workpiece. The method comprises holding the workpiece with an axis of the workpiece parallel to axes of wire guide rolls of a wire saw by means of a feed device of the10 wire saw;moving the workpiece by means of the feed device perpendicularly from above through a web of the wire saw, wherein the web is formed from a multiplicity of wire sections running parallel to one another and in one plane;15 supplying a slurry of hard substances in a carrier liquid as abrasive to the wire sections while the wire sections describe a relative movement with respect to the workpiece as a result of rotation of the wire guide rolls with a continual change in the direction of rotation, which relative movement guides the20 wire sections from an entry side to an exit side through the workpiece;spraying a coolant from the side and from below into slicing gaps that arise during the movement of the workpiece through the web, wherein the coolant is sprayed through nozzles into25 the slicing gaps, which are arranged below the web parallel to the axes of the wire guide rolls, and wherein the coolant is sprayed into the slicing gaps only through the nozzle situated opposite the entry side of the wire sections. 30 Fig. 1</p> |
