Working Fluid
Wire EDM working fluid is the functional medium through which the entire cutting process operates, serving four simultaneous roles: cooling the electrode wire and workpiece, flushing eroded particles from the cutting gap, providing the dielectric insulation that enables controlled spark discharge, and protecting machined surfaces from oxidation. The quality of the working fluid directly influences cutting speed, surface roughness, wire service life, and guide component wear.
Baoshijie working fluid is refined from high-quality base oils combined with high-efficiency additive packages, formulated specifically for the dielectric and flushing demands of high-speed and medium-speed wire EDM. There are also water-based working fluids.It delivers consistent cooling performance across extended cutting sessions, effective chip flushing to keep the cutting gap clean, and reliable anti-rust protection on freshly machined surfaces. Its lubricity reduces friction on guide wheels and conductive blocks, extending the service life of these precision wear components.
Fully compatible with Baoshijie DK77, E-type, M-type, and H-type series machines and the majority of comparable third-party machines. Suitable for die steel, hardened steel, carbide, copper, aluminum, and other conductive materials.
