摘要:

从研究水分散剂的分散机理入手,分析研究了水分散剂对电火花小孔加工的排屑、加工速度和加工质量的影响。通过电火花小孔加工中采用自来水工作液和分散剂工作液的加工效果对比,发现在电火花小孔加工的水基工作液中加入一定比例的分散剂后,不仅使电火花小孔加工的加工速度提高、电极相对损耗降低,而且有效脉冲数增加,二次放电数明显减少,工具电极作用端和被加工孔的锥度变小,加工质量提高。

Abstract:

The effects of water disperser on chip removal, material removal rate(MRR) and machining quality during small hole EDM were analyzed from setting about researching scatter mechanism of water disperser. Research results show that adding certain proportion disperser in water-based dielectric liquid during small hole EDM may increase MRR, decrease the tool wear rate(TWR), improve the effective impulse numbers, reduce the second discharge number obviously. The taper of tool electrode and processed hole become small and the hole machining quality enhances by contrasting the machining effects on using tap water with disperser dielectric liquid during electric spark small hole machining. 
