The invention discloses an ultrasonic
cutting and
polishing machining system. The ultrasonic
cutting and
polishing machining system comprises an ultrasonic
transducer, an amplitude
transformer, and awiper blade cutter, wherein the front end of the ultrasonic
transducer is tightly and reliably connected with the rear end of the amplitude
transformer; the ultrasonic
transducer is connected with anultrasonic power supply through a lead; a
flange plate is arranged at the vibration displacement node position of the amplitude
transformer; the
flange plate is connected with a B-axis rotary tool rest through a supporting plate; and the wiper blade cutter is tightly and reliably connected with the front end of the amplitude transformer. According to the ultrasonic
cutting and
polishing machiningsystem, ultrasonic high-frequency vibration in the feeding direction of the cutter can improve the action length of a wiper blade, reduce the generation of secondary
tool marks on the
machining surface of the wiper blade, and improve the quality of the
machined surface; due to the cleaning effect of the
ultrasonic vibration, it is difficult to generate
chip accumulation at the wiper edge, and thequality of the
machined surface is better guaranteed; the
ultrasonic vibration changes the contact state and action mechanism between the cutting edge and the wiper edge and the material to be machined, reduces the
cutting force and the cutting temperature, and improves the surface quality after the cutting edge is processed, and thus the quality of the
machined surface is further improved due tothe combined action of the polishing edge and the
ultrasonic vibration.
