Abstract： In order to solve the problems of self-lubricating in resin bonded abrasive tools，the microencapsule technology was used to prepare tools. After the analysis of the tribological properties of β-cyclodextrin/oleic acid complex，the relation between curing temperature and tribological properties was established. The complex as a filler to abrasive tools was presented to improve the lubricating effect of tools. The influences of curing temperature on the complex were evaluated by the Fourier infrared spectrometer. The tribological properties of complex and tools filled with complex were tested by four-ball tests and ball tray pair tests respectively. The experimental results show that curing temperature can affect complex，and the curing temperature should be lower than 165 ℃；the complex change nothing before and after curing；the good lubrication effect of abrasive tools filled with complex is attributed to the oleic acid released from complex.
