Device and method for ultra precise polishing of double-frequency acoustic cavitation nanofluid under magnetic control action

Abstract

The invention discloses a device and a method for ultra precise polishing of a double-frequency acoustic cavitation nanofluid under the magnetic control action. The device comprises a polishing liquid pool, a hydraulic pump, an ultrasonic reactor, a double-frequency ultrasound device, a nano-abrasive container, an alternating current power supply, an alternating current coil and a workpiece frame. The method is realized mainly through the following steps: (1) a polishing liquid is placed in the polishing liquid pool, and then is sent in the ultrasonic reactor through the hydraulic pump; (2) nano-abrasives are placed in the nano-abrasive container, and flow into the ultrasonic reactor through a third connecting pipe; (3) the polishing liquid and the nano-abrasives are mixed in the ultrasonic reactor into a nano-abrasive and polishing liquid mixed solution, and the mixed solution is subjected to acoustic cavitation under the action of the double-frequency ultrasound device; (4) the mixed solution is ejected under acoustic cavitation and pressure; (5) the alternating current coil generates an alternating current magnetic field, and the ejected nano-abrasive and polishing liquid mixed solution polishes a workpiece under the action of the alternating current magnetic field. According to the device and the method, the plane and the curved surfaces of parts are polished with high precision, high consistency and high surface quality.
