The invention discloses a machining device for high-precision forging and pressing parts. The machining device comprises a main machine control box; and an electrostatic strip is mounted at the bottomof the main machine control box and electrically connected with the main machine control box, and a working table is mounted at the bottom of the electrostatic strip. According to the machining device for the high-precision forging and pressing parts, the design structure adopts a mode of being straight up and down and changes a complex structure of traditional machining equipment, in this way, the working efficiency of the machining device for the high-precision forging and pressing parts can be greatly improved, energy waste in the use process is further reduced, and resource saving and using cost reducing are facilitated; a hydraulic cylinder is mounted, in work of the machining device for the high-precision forging and pressing parts, electric power is converted into the pressure to push the working table to forge and press blanks, and the loss of electric resources is reduced; and a damping rubber cushion is mounted, when the working table conducts blank forging and pressing work, vibration force produced by the working table is effectively relieved, and the precision of the blanks forged and pressed by the machining device for the high-precision forging and pressing parts isimproved.
