电火花加工机床工作液循环系统研发与应用
Development and Application of Dielectric Fluid Circulation System for EDM Machine Tools
摘要
Abstract
To address the demands of precision electrical discharge machining(EDM),a working fluid circulation system featuring high-precision filtration,stable performance and high-degree automation was developed in this paper.The system primarily comprises five modules:A power source,a multi-stage filtration unit,a temperature regulation module,a control unit,and a monitoring module.The operational parameters of key components were calculated,and the corresponding equipment was selected.A three-dimensional model of the system was established,leading to the development of a physical prototype.This prototype was integrated into an EDM machine tool for performance validation and machining trials.The performance tests confirmed that all major system parameters met the design specifications.The practical machining trials demonstrated that,compared to the original EDM system,the new system reduced the average surface roughness of inclined holes by approximately 34％,lowered that of straight holes by about 14.7％,and decreased the electrode wear rate by approximately 25.00％-26.36％.The developed working fluid circulation system exhibits significant advantages in filtration precision,system stability,and automatic control,demonstrating considerable potential for application in the field of high-efficiency precision EDM.关键词
