Abstract

Disclosed is a microhole precision-machining method based on dielectrophoresis. A device for implementing the microhole precision-machining method comprises a vibration exciter, an amplitude-change vibrating rod, an acting press plate, hole punching pieces, cylindrical positioning pins, a worktable, a base work bedplate and a hydraulic piston, a sealing shell is mounted on the worktable, a grinding liquid inlet nozzle and an opening for grinding liquid to flow back to a grinding liquid tank are formed in the sealing shell, a first electrode plate is mounted on a hole punching piece holding support, and a second electrode plate is mounted on the base work bedplate. When the vibration exciter works, the amplitude-change vibrating rod linked with the vibration exciter applies load and vibration to the hole punching pieces in hole punching piece holding support holes indirectly on the acting press plate to adjust oil pressure in a hydraulic oil chamber to enable a workpiece to be in constant contact with the hole punching pieces, so that microhole precision-machining of the workpiece is achieved. The microhole precision-machining method based on the dielectrophoresis has the advantages that machining precision, machining efficiency and machining consistency of microholes are achieved.

Description

technical field [0001] The invention relates to the technical field of precision machining, in particular to micro-hole precision machining based on the dielectrophoretic effect. Background technique [0002] With the wide application of micro-electromechanical systems in aerospace, national defense, electronic industry and other fields, system components are gradually developing towards precision and miniaturization. The precision machining of tiny holes on system components such as , ceramics, hard alloys, diamonds, and carbon fiber composite plates is becoming more and more difficult. In order to solve the technical problems of precision machining of micro-holes in difficult-to-machine materials, new processing methods are constantly being explored. [0003] The precision machining methods of tiny holes can be divided into three categories: mechanical machining, special machining and compound machining. Machining mainly includes mechanical drilling, grinding, micro-hole...
