英文摘要：

A vitrified bond CBN point grinding wheel with coarse grinding area slope angleθ was presented.The removing rate of new grinding wheels is higher and the machining accuracy is better than that of conventional wheels.The theory of grinding heat generation and distribution and infrared temperature measurement were studied.These wheels with different coarse grinding area slope angleθ were used to grind the stepped shaft of QT700 with a series of grinding parameters.Thermovision A40M were used to measure the grinding contact area temperature.The effects of different grinding parameters such as deflection angleα,grinding depth a p ,workpiece axial feed rate vf and wheel speed vs on grinding temperature were generalized.In the same group of grinding parameters,the effects of these different wheels on grinding temperature were contrasted.
