摘要
Abstract
Grinding comparative experiments of nickel-based superalloy GH4169 with both graphite self-lubrication brazed CBN wheel and vitrified CBN counterpart were carried out. Grinding temperatures of the workpiece surface were measured with semi-manual thermocouple method. The morphology of the grains on the surface of the wheel and the distribution of element were detected using scanning electron microscope ( SEM) and energy dispersion spectrometer (EDS). The results showed that the grinding temperature of graphite self-lubrication brazed CBN wheel was 100 ℃ lower than that of vitrified CBN wheel under the same grinding parameters. Moreover, a layer of graphite film was formed on the surface of the CBN grits after grinding, which indicated that the lubricant graphite could spread over the wheel surface during the grinding process and decreased the friction between the grinding wheel and the workpiece in contact zone, thus decreased the grinding
temperature.
