Description

technical field [0001] The invention belongs to the technical field of mechanical processing and relates to abrasive flow finishing, in particular to a surface-constrained ultrasonic vibration-assisted rotating abrasive flow finishing device. Background technique [0002] Abrasive streamlining is a process that uses polymer materials as a carrier, suspends cutting abrasives in it to form fluid abrasives, and deburrs, polishes, rounds, etc. through the surface of the workpiece under pressure. Abrasive flow machining is not limited by the geometric shape of the workpiece, and is suitable for processing complex surfaces such as various holes, profiles, and cross holes; it has high processing efficiency and good polishing effect; it is used in aerospace, weapons, steam turbines, textiles, molds, and hydraulic pressure. And other machinery industry has been widely used. [0003] However, due to the pressure difference between the inlet and outlet of the traditional abrasive flow...
