Influences of configuration and coating on the vibration characteristics of spindles

Strong vibration is the main factor leading to spinning spindle failure, which closely related end configuration and surface coating. In this study, effects of coating on characteristics spindles are studied, tests were conducted a multifunctional test bench by using three different types without YD4203C pointed with self-lubricating under various high-speed no-load conditions. The results showed that phenomenon pointed-head was slighter than YD6111FA frustum YD6100E flat-headed spindle, believed be because increase in area could speed up heat transfer, decrease bottom reduce impact oil gas vortex vibration. addition, coated significantly improved compared uncoated spindles. This study provides experimental basis for design manufacture low
