Abstract

Abstract

Slotted screen is an important equipment for mechanical sand, a new method via electrical discharge machining (EDM) combined electrochemical machining (ECM) is used to manufacture the screen. Aiming at the shortcomings of traditional water based working fluids, such as low processing efficiency, low kerosene flash point and poor safety, a new water-soluble working fluid for EDM combined machining was developed. The best basic working fluid was determined by orthogonal test, and sucrose, electrolyte and so on were added in the compound processing, and the difference between the compound processing and the oil processing was compared. The results showed that at a temperature of 30℃ the ratio of pure water, polyethylene glycol 400 and triethanolamine was of 11:11:3, and the performance of the basic working fluid with a mass fraction of 10% was the best. The best processing effect can be obtained by adding 35 g sucrose on the basis of 1g NaNO₃ and 0.25gNaCl. Compared with the working fluid of oil processing, the surface roughness was reduced, the processing efficiency was reduced and the width of the seam was increased, and the cleanness and safety were improved.
