Problems solved by technology

Due to the relatively small size of micro-ultrasonic machining, tool electrode clamping is a problem, and it is difficult to ensure the verticality and coaxiality of the tool electrode, which will bring large processing errors; Abrasive particles vibrate out of the processing area, causing no abrasive particles in the processing area, which affects the efficiency of micro-ultrasonic processing

Abstract

The invention discloses an electrophoresis auxiliary micro-ultrasonic machining tool and a method for implementing electrophoresis auxiliary micro-ultrasonic machining by the utilization of the machine tool. The machining tool comprises a spindle system, an electricity feeding system, a spindle micro-ultrasonic longitudinal vibration system and a multi-functional cup-shaped working solution groove. A novel combined machining technology is provided, absorption of electrophoreses is added to the micro-ultrasonic machining, so that micro abrasive grains in ultrasonic machining working solution are driven by electric field force to move to neighborhood of a machining area, and existence of the abrasive grains in the machining area is guaranteed. The utilization ratio of the abrasive grains can be effectively improved, so that the efficiency of the micro-ultrasonic machining is improved.

Description

technical field [0001] The invention relates to a machine tool in the technical field of special processing, in particular to a multifunctional micro-machining machine tool integrating micro-electric discharge machining, micro-ultrasonic machining, and electrophoresis-assisted micro-ultrasonic machining. Background technique [0002] With the development of science and technology, the demand for microstructures of hard and brittle materials, tiny parts and tiny products is increasing in the fields of electronics, optics, machinery, biotechnology, automobiles, communications and other industries. At present, the methods suitable for the micro-processing of hard and brittle materials mainly include micro-ultrasonic machining and micro-laser machining. Since micro-ultrasonic machining has neither thermal action nor macro-mechanical force, but also can process micro three-dimensional structures with high aspect ratio, the surface quality and machining accuracy of parts are good,...
