In order to improve the machining accuracy of lubricating pad used in joint bearings, this paper put forward the application of laser vaporization cutting technology in the production process, and systematically studied the process steps of lines. The main contents included: the graphical layout and location of liners, the laser cutting parameters of three typical self-lubricating liners, and the detection requirements. The cutting gap changes and depth changes were analyzed with the help of stereomicroscope. Finally, the self-lubrication liners were used on spherical plain bearings to verify the reliability. The results showed that the layout of laser cutting routes by using computer is compact, the visualization is more convenient and flexible, and even could be used repeatedly. Laser cutting positioning is simple and convenient. The cutting effect is negatively correlated with the laser frequency and laser traverse speed, and positively correlated with the duty cycle. The best parameters for liner cutting were obtained: the laser frequency is 20~30 kHz, the laser traverse speed range is between 150 mm/s and 200 mm/s, the duty cycle is 50%, and cutting times is the number of the liner which are just falling off.
