Abstract

A rotary ultrasonic-assisted micro electrolytic grinding hole reaming processing device and method, on the basis of using a micro electrolytic machining machine tool to perform electrolytic drilling to obtain a pre-hole, perform online tool change operations on the machine tool to avoid positioning errors, and add axial Ultrasonic vibration and high-frequency pulse power are used for electrolytic grinding and reaming of pre-holes. Utilize the cavitation effect and enhanced mass transfer effect of ultrasonic vibration to disturb the electrolyte, promote the timely discharge of the precipitated gas and other electrolytic products in the processing area, and make the gap flow field and gap electric field more uniform, so as to improve processing efficiency and repeat processing accuracy and surface finish quality. The high-frequency pulse power supply is used to realize the micro-removal of the workpiece, improve the processing localization and size controllability, and facilitate the precise adjustment of the matching between electrolytic machining and mechanical grinding. The invention has the functions of improving the processing precision of the small hole and the surface processing quality while ensuring the processing efficiency.

Description

technical field [0001] The invention belongs to the technical field of electrolytic grinding composite processing, and in particular relates to a rotary ultrasonic-assisted micro electrolytic grinding hole reaming processing device and method. Background technique [0002] The small hole structure is widely used in many engineering fields, such as 3D printer nozzles, engine fuel nozzles, air film cooling holes in aeroengine blades, special-shaped holes on chemical fiber spinnerets, and small holes on instruments and meters. The surface quality of the hole wall often determines the quality and performance of small hole parts, so the demand for ultra-precision machining of small holes is becoming more and more urgent. [0003] Electrolytic grinding composite processing has the advantages of high surface processing quality and processing accuracy in many small hole processing methods. The Chinese invention patent with the publication number "CN 103447640A" discloses an electrol...
