Problems solved by technology

The disadvantages of kerosene are obvious, mainly because of the low flash point (about 46°C), which may cause fire due to accidental negligence during use, and its high aromatic content is volatile, and many harmful gases are produced by processing and decomposition.
Moreover, when the processing area is large, it is not easy to perform stable finishing in kerosene working fluid, and a good processing surface cannot be obtained.
In addition, the processing efficiency and electrode wear in kerosene are not very satisfactory

Abstract

The invention discloses a low-speed wire cut electrical discharge machining solution. The low-speed wire cut electrical discharge machining solution comprises 15 to 25wt% of white oil, 10 to 20wt% of higher fatty alcohol, 2 to 8wt% of tetraacetylethylenediamine, 0.5 to 1.0wt% of sodium molybdate, 0.05wt% of nano-alumina powder, and the balance 100# machine oil. The low-speed wire cut electrical discharge machining solution has a high flash point, good processability and a long service life, and does not influence a human body and a machine.

Description

technical field [0001] The invention relates to the field of electrical discharge machining, in particular to a slow-moving wire electrical discharge machining working fluid. Background technique [0002] Discharge machining is a processing method that uses the electric corrosion phenomenon during pulse discharge between the tool electrode and the workpiece electrode to process the material in a certain medium to achieve a certain shape, size and surface roughness. When a single pulse discharge is performed in a small gap of a liquid medium, the electrocorrosion process of the material can be roughly divided into three continuous processes: dielectric breakdown, channel formation, energy conversion and transfer, and electrocorrosion product ejection. When molding a conductive workpiece, the space between the two electrodes must be filled with a liquid medium, which is the aforementioned EDM working fluid. [0003] EDM working fluid must have high dielectric strength to faci...
