摘要

A machining platform of micro wire electrical discharge machining (MWEDM) was developed. The key technology of MWEDM mainly includes granite basement, micro energy pulse generator, detection and servo control system, constant tension winding system and V-block guide wire mechanism. Utilizing micro wire electrode with 30 μm in diameter, the MWEDM can machine the micro slot with the minimum size of 38 μm wide, and the surface roughness is smaller than 0.1 μm, the machining precision is less than 0.5 μm, the white layer is no more than 2 μm with main cut. All kinds of complex micro parts, such as micro gear, micro bearing bracket and micro shaped holes, can also be machined by using this platform.
