A kind of high-flatness metal surface electrochemical jet modification processing device and method

Abstract

The invention discloses a high-flatness metal surface electrochemistry jet flow modification processing device and method. The high-flatness metal surface electrochemistry jet flow modification processing device comprises an X-direction linear guide rail mechanism, a C-direction rotary table, a leveling device, an adapter plate, an electrolytic bath, an electrode, a force sensor, a laser displacement sensor, a Z-direction linear guide rail mechanism, a Y-direction linear guide rail mechanism, an electrolyte hydraulic circulation system, a motion controller and an optical platform. According to electrochemistry jet flow modification processing provided by the invention, material removal is independent of mechanical acting force, and a surface residual stress layer can be avoided effectively; and the material removal process is independent of abrasive grains, and abrasive grain pollution and scratch defects left on the processed surface are avoided effectively. A workpiece is only placed in the electrolytic bath, no special clamp is needed for fixing and clamping, and clamping stress causing large deformation of the workpiece is not generated in the processing process. Removal functions of electrochemistry jet flow modification processing for different metal materials are determined, thus processing of any metal materials can be achieved, and universality is achieved.

Description

technical field [0001] The invention belongs to the field of ultra-precision machining, and in particular relates to a high-flatness metal surface electrochemical jet flow modification processing device and method. Background technique [0002] Metal has good electrical conductivity, thermal conductivity, optical properties, and machinability, and it is processed into high-precision surfaces and widely used in optical, electromechanical and other fields. High flatness metal parts are often used as reflectors, valve parts and various models, etc. The surface flatness and roughness have a great influence on the performance of parts. Traditional various cutting processes are common processing methods for metal parts, but the flatness can only reach the order of ten microns, and the surface roughness is on the order of microns, which cannot meet the use requirements of the above-mentioned types of parts. The single-point diamond turning (English: single-point diamond turning, a...
