Abstract

Provided is a metal surface micro texture array electrode direct writing micro electrolysis processing method and a dedicated device. The processing method includes a first step of processing metal surface micro texture of workpieces to be processed by adopting line-shaped array electrodes, and a second step of enabling the array electrodes to conduct relative movement with the workpieces to be processed under the control of a machine tool numerical control system and processing the micro texture out of the surfaces of the workpieces to be processed under the conditions of flow of electrolyte and power-on of a processing power supply. The dedicated device comprises a machine tool, an electrolyte circulating device, a line-shaped array electrodes, a computer and a power supply provided with an anode and a cathode, the electrolyte circulating device and the line-shaped array electrodes are respectively in electric connection with the computer and meanwhile controlled by the machine numerical control system matched with the computer. The metal surface micro texture group electrode direct writing micro electrolysis processing method and the dedicated device has the advantages of being capable of processing complicated texture structure with the electrodes in simple shapes, free from need to manufacture a mask plate, short in processing cycle, high-efficiency, capable of avoiding deformation of the surfaces of the workpieces and 'secondary processing' and good in quality.
