The ultrasonic combined electrical micro-machining new technology is advanced for manufacturing micro-instruments and micro-structures. The ultrasonic combined electrical micro-machining systems with machining parameters adjustable in a wide range are built and improved. The micro-machining mechanism is analyzed and discussed. Micro-tool electrodes in different sections and sizes that can meet testing and actual machining requirements are manufactured by combined electrical discharge micro-machining. Multi-parameter ultrasonic combined electrical micro-machining tests are carried out. The results show that the ultrasonic combined electrical micro-machining new technology has the advantages of high machining efficiency and accuracy and low cost. This technology is used to manufacture friction pair surface lubricant retention micro-structures. The friction tests prove that the lubricant retention micro-structures can reduce friction coefficient and wear of friction pair surfaces.
