Abstract

The invention relates to a carbon nano tube fiber tool cathode suitable for micro-electrolysis linear cutting and a preparation method of carbon nano tube fiber tool cathode, and belongs to the fieldof micro electrochemical machining. The preparation method is characterized by comprising the following steps that carbon nano tube fibers are installed on a wire electrode clamp through a conductivefastening screw firstly; then, a metal is plated on a local surface or a whole surface of the original carbon nano tube fibers through a micro-electroplating method, so that the overall conductivity is improved, and the requirements of micro-electrolysis linear cutting machining are met; and finally, the excellent surface hydrophilicity of the carbon nano tube fibers and reciprocating vibration ofthe carbon nano tube fibers in a direction perpendicular to a feeding direction are utilized, so that the mass transfer rate in a micro machining gap is accelerated, and the stability and the efficiency of micro-electrolysis linear cutting machining are improved.

Description

technical field [0001] The invention relates to a method for preparing a cathode of a micro-electrolytic wire-cut carbon nanotube fiber tool, which belongs to the field of micro-electrochemical processing. Background technique [0002] Micro electrolytic wire cutting technology is a subtractive manufacturing method based on the principle of electrochemical anodic dissolution. It uses a metal wire with a diameter of several microns to tens of microns as the tool wire electrode. By combining multi-axis CNC motion, it can realize the preparation of any shape of the planar profile structure, especially suitable for micro-slits, micro-grooves and large aspect ratios. Processing of metal microstructures. Compared with other micromachining methods, microelectrolytic wire cutting technology has the characteristics of wide processing range (not limited by material strength and hardness), high efficiency, no recast layer and microcracks on the surface, and no loss of tool electrodes....
