Due to the high conductivity of the pure water-based working fluid, it has a strong electrolysis in the cutting process. Although the surface of the cut workpiece is very uniform, the surface of the workpiece due to electrolysis will lead to a darker color. Sub-cutting is more pronounced;
Since the pure water-based working fluid does not have an oily component, when it volatilizes, the cut-off etching product adheres to the worktable and around the guide wheel, and the cleaning is difficult. In severe cases, the guide wheel will be locked even after the wire is transported. The friction between the electrode wire and the guide wheel will cause the guide wheel to lose accuracy and be scrapped;
· Wire-cutting water-based working fluid because of its strong alkaline, long-term use will make the machine paint surface blistering and fading;
· Wire cutting water-based working fluid must strictly control the dilution ratio, otherwise it is easy to rust machine tools and workpieces;
· Wire-cutting water-based working fluids are highly volatile, and at the same time due to the compositional problems, some odors are generally emitted during the cutting process.
Common defects in wire-cut pure water-based working fluids
Currently, the market for wire-cut pure water-based working fluids generally has the following defects:
