摘      要：Profiled monolayer cBN wheel was induction brazed for grinding of titanium dovetail slot in this *** at acquiring a uniform temperature distribution along the profiled surface and reducing the thermal deformation of the brazed wheel,a finite element model was established to investigate the temperature uniformity during induction brazing.A suitable induction coil and the related working parameters were designed and chosen based on the simulation ***-Cu-Ti alloy and cBN grains were applied in the induction brazing *** results showed geometric deformation of the brazed wheel was no more than 0.01 mm and chemical reaction layer were found on the brazed joint *** validation tests were carried out by grinding of Ti-6 Al-4 V *** to the electroplated wheel,the brazed wheel showed better performance such as low specific grinding energy and good ground quality in grinding of Ti-6 Al-4 V *** wear was found to be the main failure mode for the induction brazed wheel,while adhesion and grains pull-out were the main failure mode for the electroplated wheel.
