Break splitting apparatus and split splitting method for splitting a workpiece

摘要

A fracture-splitting method and a fracture-splitting apparatus for fracture-splitting workpieces having a cooling device for cooling the workpiece in a splitting zone, and having a fracturing device for fracture-splitting the workpiece in the region of the cooled splitting zone, wherein an inflow coolant duct opens out at at least one outlet opening of the cooling device in order to cool the splitting zone, wherein the cooling device has at least one sealing portion for bearing in a sealing manner against the workpiece next to the splitting zone in order to cool the workpiece in the splitting zone in a locally delimited manner, and/or has at least one admission opening of at least one outflow coolant duct, said admission opening being arranged next to the at least one outlet opening of the inflow coolant duct, in order to conduct the coolant away from the splitting zone of the workpiece.
