Abstract: A multi-angle two-dimensional ultrasonic vibration assisted nanofluid micro-lubrication grinding device includes a workpiece fixture for clamping a workpiece and a grinding wheel for grinding the workpiece, the fixture being connected with a two-dimensional ultrasonic vibration device to maintain the sharpness of the grinding wheel cutting edge and cool the grinding temperature on the workpiece surface; a jetting mechanism used for jetting nanofluid to the workpiece is arranged on one side of the grinding wheel so as to form two-dimensional ultrasonic vibration and nanofluid micro-lubrication grinding coupling; the device applies the variable-angle two-dimensional ultrasonic vibration technology to grinding processing, and adjusts the angles of two ultrasonic vibrators to generate different combined vibration directions to change the relative movement trajectories of abrasive particles and a workpiece. A grinding force and grinding temperature are detected in real time by force measurement and temperature measurement devices, meanwhile cooperation with nanofluid micro-lubrication is utilized.
