Increasing the effectiveness of deep grinding of the locking element of a turbine blade with an "Aerobor® II" highly porous cubic boron nitride grinding wheel

Abstract

The results of testing new generation Aerobor® II cubic boron nitride grinding wheels during machining of the locking element of turbine blades are presented. The advantages of using new high-porosity cubic boron nitride grinding wheels in comparison with abrasive grinding wheels in deep grinding of parts made of heat-resistant nickel alloys are described.
