Abstract
The results of the implementation of high-porous cubic boron nitride (CBN) grinding wheels in the operation of double-sided deep grinding of the fir-tree profile of the locking element of the turbine blade are presented. The features of designing the working layer of the CBN wheel for this operation are described. Recommendations for the selection of the characteristics of diamond dressing rollers are formulated. The principles of organizing an efficient production process when introducing CBN grinding wheels are described. Keywords: deep grinding, part, gas turbine engine, working turbine blade, grinding wheel dressing, diamond profile roller, highly-porous CBN grinding wheels. d_i_volkov@rsatu.ru, boris_tsvetkov@mail.ru
