Rotational ultrasonic effects were integrated with grinding and electrolysis effectively to achieve precision and high-efficiency processing of difficult-to-machine materials and complex shaped parts. A rotary ultrasonic composite electrolytic grinding system was designed and developed. Experimental schemes were designed to conduct mechanical grinding, ultrasonic grinding and rotary ultrasonic combined electrolytic grinding experiments on aluminum and SiCp/Al particle-reinforced ceramic materials. The forming mechanism of rotary ultrasonic combined electrolytic grinding is analyzed, and the influence mechanism of different parameters on machining precision, efficiency and surface quality is studied. Based on its mechanism, the parameters of rotary ultrasonic combined electrochemical grinding system were optimized. The results show that rotary ultrasonic combined electrochemical grinding can effectively reduce the cutting force and heat, ensure the removal of electrode materials and electrolyte circulation renewal in time, and enhance and stabilize the machining effect.When the voltage is 3 V, the precision of machining an aero-engine blade can reach 0.01 mm and the surface roughness can be less than 0.80 μm.The method of rotary ultrasonic combined electrochemical grinding has obvious technical advantages.
