Tangent Hole Machined by Micro Electrical Discharge Machining

扫码查看
Based on a self-developed pulse power supply, effects of working fluid to machining efficiency and relative wear of electrode are studied, tangent-hole machining experiments are designed and carried out. Tangent holes with 0.75mm and 0.56mm diameters on some nozzles are obtained.
