A group of narrow groove electrolytic grinding and milling processing devices and methods thereof

Abstract

The invention discloses a group narrow groove electrolytic grinding and milling machining device and method thereof. The group narrow groove electrolytic grinding and milling machining device comprises a power source, a workpiece, a group composite grinding wheel, an electrolyte box, a rotary driver, a front-back moving mechanism and an up-down lifting mechanism. According to the group narrow groove electrolytic grinding and milling method, the group composite grinding wheel is driven by the rotary driver to rotate, the group composite grinding wheel is inserted into the electrolyte in the electrolyte box, the group composite grinding wheel rotates at a high speed to bring the electrolyte into a machining gap, the workpiece material in the machining gap generates a passive film under the combined action of an electric field and a flow field, the workpiece is driven by the front-back moving mechanism to move in the X-axis direction, the workpiece can be controlled to be continuously fedtowards the group composite grinding wheel, then the generated passive film is ground, milled and removed by the group composite grinding wheel rotating at a high speed, the exposed new metal matrixis continuously subjected to electrochemical reaction to generate a new passive film, and the steps are repeated until the required group narrow groove is machined.

Description

technical field [0001] The present invention relates to an electrolytic milling device and its method, more specifically, to a group of narrow slot electrolytic milling device and its method. Background technique [0002] Workpieces that need to be machined with narrow grooves are mostly used in heat dissipation components of complex mechanisms, which require a large amount of heat, and the efficiency of ordinary machining is low, and most of the workpieces are thin-walled parts, which are difficult to clamp during processing and easily deformed after the processing stress is released; while the traditional Electrolytic grinding is surface processing (the machining depth in one pass is very small), the processing efficiency is low, and because the electrolyte is mainly sprayed outside, the controllability of the dispersed electrolyte is poor, and it is easy to cause stray corrosion, which leads to low processing accuracy. Contents of the invention [0003] 1. The technical...

The efficiency of ordinary machining is low, and most of the workpieces are thin-walled parts, which are difficult to clamp during processing and easily deformed after the processing stress is released; while the traditional Electrolytic grinding is surface processing (the processing depth in one pass is very small), the processing efficiency is low, and because the electrolyte is mainly sprayed outside, the dispersed electrolyte is poorly controllable, and it is easy to cause stray corrosion, which in turn makes the processing accuracy low
